SIP
SIP, the session initiation protocol, is the IETF protocol for VOIP and other text and multimedia sessions, like instant messaging, video, online games and other services.
Abstract from the RFC 3261 (formatted_and_explained version) - SIP: Session Initiation Protocol
This document describes Session Initiation Protocol (SIP), an application-layer control (signaling) protocol for creating, modifying, and terminating sessions with one or more participants. These sessions include Internet telephone calls, multimedia distribution, and multimedia conferences.
SIP invitations used to create sessions carry session descriptions that allow participants to agree on a set of compatible media types. SIP makes use of elements called proxy servers to help route requests to the user's current location, authenticate and authorize users for services, implement provider call-routing policies, and provide features to users. SIP also provides a registration function that allows users to upload their current locations for use by proxy servers. SIP runs on top of several different transport protocols.
SIP is very much like HTTP, the Web protocol, or SMTP. Messages consist of headers and a message body. SIP message bodies for phone calls are defined in SDP -the session description protocol.
SIP offers all potentialities of the common Internet Telephony features like:
Since SIP is a flexible protocol, it is possible to add more features and keep downward interoperability.
SIP also does suffer from NAT or firewall restrictions. (Refer to NAT and VOIP)
SIP can be regarded as the enabler protocol for telephony and voice over IP (VoIP) services. The following features of SIP play a major role in the enablement of IP telephony and VoIP:

SIP is very much like HTTP, the Web protocol, or SMTP. Messages consist of headers and a message body. SIP message bodies for phone calls are defined in SDP -the session description protocol.
- SIP is a text-based protocol that uses UTF-8 encoding
- SIP uses port 5060 both for UDP and TCP. SIP may use other transports
SIP offers all potentialities of the common Internet Telephony features like:
- call or media transfer
- call conference
- call hold
Since SIP is a flexible protocol, it is possible to add more features and keep downward interoperability.
SIP also does suffer from NAT or firewall restrictions. (Refer to NAT and VOIP)
SIP can be regarded as the enabler protocol for telephony and voice over IP (VoIP) services. The following features of SIP play a major role in the enablement of IP telephony and VoIP:
- Name Translation and User Location: Ensuring that the call reaches the called party wherever they are located. Carrying out any mapping of descriptive information to location information. Ensuring that details of the nature of the call (Session) are supported.
- Feature Negotiation: This allows the group involved in a call (this may be a multi-party call) to agree on the features supported recognizing that not all the parties can support the same level of features. For example video may or may not be supported; as any form of MIME type is supported by SIP, there is plenty of scope for negotiation.
- Call Participant Management: During a call a participant can bring other users onto the call or cancel connections to other users. In addition, users could be transferred or placed on hold.
- Call feature changes: A user should be able to change the call characteristics during the course of the call. For example, a call may have been set up as 'voice-only', but in the course of the call, the users may need to enable a video function. A third party joining a call may require different features to be enabled in order to participate in the call
- Media negotiation: The inherent SIP mechanisms that enable negotiation of the media used in a call, enable selection of the appropriate codec for establishing a call between the various devices. This way, less advanced devices can participate in the call, provided the appropriate codec is selected.

The SIP protocol defines several methods. ...↧

Routing calls using a free international calling service
Recently a few services have popped up that allow "free" calls to various international points. There are all based in the U.S. state of Iowa, and the way they work is that you call a regular number in Iowa, wait for a prompt, then dial the number you want to call. As best anyone can determine, there must be some quirk in Iowa telecommunications law that allows them to charge higher than normal termination charges on connected calls, and they use VoIP to complete the calls, so they actually wind up making anywhere from a fraction of a cent to a few cents on each minute of use. If the Federal Communications Commission ever reforms the ridiculous compensation system we have here, these companies will probably be out of business overnight.
NOTE: on January 29, 2007 AT&T filed a lawsuit that "seeks to stop FuturePhone as well as the telcos who provide local infrastructure from continuing with their operations that use regulatory-fee arbitrage and VoIP to provide international calls for only the price of a long-distance call to Iowa." (quote from linked article). This has already resulted in some of these companies discontinuing or modifying their service.
For now, if you have "free" calling within the USA, and can place calls to the Iowa numbers that are still in operation, you can then get connected through to numbers in other countries, including Mexico (which is a fairly high cost call on many U.S. long distance plans) at no additional charge.
The challenge, then, is whether Asterisk/FreePBX can work in this manner. Assuming a user dials an international call to certain countries, select an outbound trunk (that allows completion of U.S. calls) and then do the following:
1) Connect to a particular U.S. number (NOT the number dialed by the user),
2) Wait for the other end to answer, then wait until it is ready to receive digits (a couple seconds timeout may work),
3) Send DTMF tones, possibly interspersed with waits, to the other end, representing the number the caller originally dialed, but the number MIGHT have to be massaged a bit. For example, if the caller is in a country where you dial 00+country code+number and the U.S. system expects 011+country code+number, you'd need to strip the "00" and add the "011." Also I believe one of the systems has an initial prompt that is something like "press 1 for English, press 2 for Spanish" so in some cases there may be a need to prepend additional digits and/or wait states.
Now, I have determined that it IS possible to have Asterisk send post-connect DTMF digits and waits. For example, if you were to add this to extensions_custom.conf in FreePBX or Trixbox:
exten => *20,1,Dial(Local/18005558355@outbound-allroutes,,D(wwwwww932))
exten => *20,2,Hangup
Assuming you had a route for U.S. 1-800 numbers, when the user dials *20 it would place a call to the "TellMe" service, then wait three seconds, then send DTMF for 932 ("WEA") which would take you directly to the WEAther forecast section (to further automate it for a particular location, you could add a few more waits - I've found that wwwwwwww is about right - after the 932, and then a five-digit U.S. zip code). The point is that the caller never hears the tones that are being sent because the audio path doesn't connect until after the digits have been sent (which would make this technique useful for sending account codes, etc.)
I will list a few of these "free" international call services below. Remember that the numbers you have to call are NOT toll free, so they are only "free" if you have unlimited U.S. calling, or are using a cell phone with "free" airtime, etc. Also, I have no connection to any of these companies, so I cannot say whether they might save the calling or called numbers for any reason - obviously if you are highly concerned about privacy of communications, you would want to investigate these services further before using them. Please note that the list of countries that can be called through each provider may change without notice. ...

STUN
STUN (Simple Traversal of UDP through NATs (Network Address Translation)) is a protocol for assisting devices behind a NAT firewall or router with their packet routing. RFC 5389 redefines the term STUN as 'Session Traversal Utilities for NAT'.
Note: The STUN RFC states: This protocol is not a cure-all for the problems associated with NAT.
Various types of NAT (still according to the RFC)
The problems with STUN are not design flaws in STUN. The problems in STUN have to do with the lack of standardized behaviors and controls in NATs. The result of this lack of standardization has been a proliferation of devices whose behavior is highly unpredictable, extremely variable, and uncontrollable. STUN does the best it can in such a hostile environment. Ultimately, the solution is to make the environment less hostile, and to introduce controls and standardized behaviors into NAT. However, until such time as that happens, STUN provides a good short term solution given the terrible conditions under which it is forced to operate.
STUN RFC RFC 5389 (Current as per October 2008)
Note: The STUN RFC states: This protocol is not a cure-all for the problems associated with NAT.
- STUN enables a device to find out its public IP address and the type of NAT service its sitting behind.
- STUN operates on TCP and UDP port 3478.
- STUN is not universally supported by VOIP devices yet. Support as of 2015 is fairly good, but legacy devices may lack it.
- STUN may use DNS SRV records to find STUN servers attached to a domain. The service name is _stun._udp or _stun._tcp
Definitions (from the RFC)
- STUN Client: A STUN client (also just referred to as a client) is an entity that generates STUN requests. A STUN client can execute on an end system, such as a user's PC, or can run in a network element, such as a conferencing server.
- STUN Server: A STUN Server (also just referred to as a server) is an entity that receives STUN requests, and sends STUN responses. STUN servers are generally attached to the public Internet.
Various types of NAT (still according to the RFC)
- Full Cone: A full cone NAT is one where all requests from the same internal IP address and port are mapped to the same external IP address and port. Furthermore, any external host can send a packet to the internal host, by sending a packet to the mapped external address.
- Restricted Cone: A restricted cone NAT is one where all requests from the same internal IP address and port are mapped to the same external IP address and port. Unlike a full cone NAT, an external host (with IP address X) can send a packet to the internal host only if the internal host had previously sent a packet to IP address X.
- Port Restricted Cone: A port restricted cone NAT is like a restricted cone NAT, but the restriction includes port numbers. Specifically, an external host can send a packet, with source IP address X and source port P, to the internal host only if the internal host had previously sent a packet to IP address X and port P.
- Symmetric: A symmetric NAT is one where all requests from the same internal IP address and port, to a specific destination IP address and port, are mapped to the same external IP address and port. If the same host sends a packet with the same source address and port, but to a different destination, a different mapping is used. Furthermore, only the external host that receives a packet can send a UDP packet back to the internal host.
Closing words (also from the obsolete RFC 3489)
14.6 In ClosingThe problems with STUN are not design flaws in STUN. The problems in STUN have to do with the lack of standardized behaviors and controls in NATs. The result of this lack of standardization has been a proliferation of devices whose behavior is highly unpredictable, extremely variable, and uncontrollable. STUN does the best it can in such a hostile environment. Ultimately, the solution is to make the environment less hostile, and to introduce controls and standardized behaviors into NAT. However, until such time as that happens, STUN provides a good short term solution given the terrible conditions under which it is forced to operate.

Ecessa
Ecessa Corporation manufactures network control hardware and software for data and telecommunications. Since 2000, the company has focused on Internet, cloud and wide area network technologies to give business networks greater reliability, redundancy and the ability to confidently use more affordable types of bandwidth.
Ecessa did this initially with PowerLink™, which bundles multiple WAN lines (T1, xDSL, Cable, ISDN, Wireless, Satellite, etc.) into a greater pool of available bandwidth while providing business continuity through ISP failover and redundancy.
Next they added ShieldLink™, which incorporates all the capabilities of PowerLink™ and brings network security to the next level with a built-in firewall and VPN gateway.
ClariLink™ incorporates all of the above features, plus provides real-time call failover for hosted VOIP. ClariLink optimizes call performance by managing traffic among multiple Internet links to avoid jitter, latency and congestion.
ClariLink monitors all VoIP calls (incoming and outgoing) in real time. In the event of a WAN failure or call degradation (i.e. high latency, excessive jitter, packet loss, etc) it automatically moves active VoIP calls to better performing WAN links, without the call dropping or the user even noticing.
This means that business VoIP users and providers never have to worry about another dropped or low-quality VoIP call. Ecessa is the only service/product offering this advanced feature.
Ecessa's most advanced products, WANworX™ software-defined wide area network (SD-WAN) solutions, are the most scalable and flexible technology for improving WAN performance and ensuring Never Down™ network availability. WANworX enables enterprises with multiple locations to seamlessly connect all their locations plus connect to the Internet and cloud-based networks.
By integrating multiple WAN links from different carriers, WANworX supports multiple paths for data to travel, and continuously monitors links and routes traffic over the best-performing links, ensuring not only seamless uptime but also predictable application performance, even when carrier service level fluctuate. This is particularly important for real-time applications, such as VoIP, videoconferencing and VDI, where even a slight delay can result in dropped calls, glitchy video and dropped sessions - plus wasted time while all those services must reconnect.
Ecessa products enable network engineers to strategically design wide area networks they way they want to, add links, add rules, and not shy away from complex multi-layered networks that will accomplish their performance goals. And it allows them to manage the whole thing confidently with cloud-based controls.
Within the Ecessa suite of products, you'll find solutions for:
- VoIP Failover and Monitoring
- Multi-ISP WAN Failover
- Intelligent Inbound and Outbound Load Balancing
- Proactive monitoring and reporting of WAN network traffic
- Network Traffic and Application Visibility, Traffic Shaping and Application Prioritization

Call Accounting Software
A Call Accounting System is a telecommunications software or hardware application that captures, records, and costs telephone usage events. Internationally call accounting systems may be referred to as call logging systems. Call accounting systems detect outbound and inbound calls, call ring outs, call routings, abandoned calls, and other activities..
The Sarbanes-Oxley Act established new or enhanced standards for financial reporting by public companies and accounting firms, obliging them to examine and revise their internal governance, accounting and reporting controls. Examples of those "internal controls" include procedures for securing, protecting and ensuring the availability of critical infrastructure (like telecommunications systems), monitoring those systems for performance issues, and preventing or quickly detecting unauthorized attempts to acquire company records or assets.
Call accounting applications help facilitate regulatory compliance by providing tools to aggregate, monitor and analyze telecommunications data in order to correctly track and report expenses. They can be used to enhance corporate accounting practices by documenting fraud-related costs to substantiate telephony-related disputes with carriers. And they can automate the monitoring of internal communications to improve visibility into sales and financial processes.
Common Applications of Call Accounting
Service Billing and Provisioning
Call accounting systems may provide packaging, pricing, provisioning, billing, and posting or presentment of telephone services for purposes of revenue generation. Professional services firms utilize call accounting software for account code or client based billing of their phone usage. The hospitality industry uses call accounting to resell phone services to visiting guests and groups. These call accounting systems often provide accessible application-specific rating and provisioning capabilities found generally on carrier-level operational support systems (OSS) and business support systems (BSS).Departmental and Employee Chargeback
The original purpose of call accounting systems was within corporate entities for purposes of cost allocations within the enterprise. Enterprises use call accounting to allocate costs back to divisions, departments, and even individual employees. Such systems may also provide data directly to corporate accounting and human resource systems.Cost and Revenue Optimization
Call accounting software can reconcile multiple telecom carrier's billing reports by integrating telecom invoices, wireless billing, long distance charges and calling cards into a single platform, allowing your business to use the convergent expense software to provide management reports, analytic reports, alerts and robust presentationsStaff Productivity
Call accounting systems provide visibility into the calling patterns and activity of employees and can be used to minimize productivity losses through non-business calling activity. They can also be used to evaluate the effectiveness of revenue-generating staff and sales processes, and manage the responsiveness of customer service staff.Network Optimization
Companies also use call accounting systems to determine whether their voice and data networks are being utilized efficiently, in a cost effective manner, or to capacity. Call accounting applications are used to monitor network activity and bandwidth, identify over- and under-used trunks to optimize trunking configurations, pinpoint the root cause of circuit outages, monitor call routing effectiveness, queue times, abandoned calls and other information, and report usage trends and statistics. Call accounting can help companies more efficiently allocate telecom resources and make better planning decisions affecting a telecommunications network.Security and Compliance
Call accounting applications enable IT departments to shield companies from a variety of internal and external security threats by monitoring for network attacks, intrusion attempts and telecom activity that exceeds acceptable or established thresholds.The Sarbanes-Oxley Act established new or enhanced standards for financial reporting by public companies and accounting firms, obliging them to examine and revise their internal governance, accounting and reporting controls. Examples of those "internal controls" include procedures for securing, protecting and ensuring the availability of critical infrastructure (like telecommunications systems), monitoring those systems for performance issues, and preventing or quickly detecting unauthorized attempts to acquire company records or assets.

Autodialer
What Is An Autodialer?
The following definition for Autodialer appears on Wikipedia.- '"An autodialer is an electronic device that can automatically dial telephone numbers to communicate between any two points in the telephone, mobile phone and pager networks. Once the call has been established (through the telephone exchange) the autodialer will announce verbal messages or transmit digital data (like SMS messages) to the called party."'
Autodialing Techniques
Autodialing can take on many forms including connecting calls to agents versus simply playing a recorded message. The following Auto Dialer Types are available from companies such as 3CLogic and Database Systems Corp.:- Voice Broadcasting delivers a pre-recorded message to live answers and answering machines. If another call status is detected (busy, etc.), the phone systems can reschedule the call for a later time. Simple messages can be delivered or the call recipient can be presented with an IVR script that accepts touch phone responses.
- Preview Dialer allows a phone agents to view the call information prior to the call being placed. The agent can decide not to initiate the call.
- Progressive Dialer passes the call information to the agent at the same time the number is being dialed by the phone dialer. The agent usually has a few seconds to view the call information, but cannot stop the call process. Often referred to as Forced Preview Dialing.
- Predictive Dialer is more sophisticated because the phone dialer automatically calls several numbers and only passes a call to an agent when a person has been contacted. This eliminates busy signals, answering machines, etc.
- Smart Predictive Dialer places calls, plays recorded messages and prompts, and passes the calls to agents only when the called individual requests a contact. "
Autodialing Equipment
Autodialers are usually desktop computers equiped with either special telephony voice boards or off-the-shelf voice modems. Traditionally, voice modems lack many of the features telephony boards offer. For example, call progress detection, call transfer, etc. However, with the ever improvement in today's computer speed, many of the telephony board features are implemented in software, which drastically reduces the cost and improves flexibility. Examples of such equipment are 3CLogic's Autodialer and Voicent BroadcastByPhone Autodialers, which offer all features offered by telephony board based autodialer systems and many more.Another advantage of using a voice modem based system is that it can turn a laptop computer to an autodialing system. There are good quality USB based voice modems, such as those from Creative Lab and Zoom.
