  • 01/14/16--03:47: Sip Trunking Providers
  • This page is a list of SIP trunking providers around the world. Please keep this list in alphabetical order. SIP providers looking to add their services can do so in the list below.

    Country specific pages:

    What Is SIP Trunking?

    Traditional phone calls go over phone lines, but with the rise of the internet, Voice Over IP communication systems give you much more functionality to receive a high volume of calls. This is called SIP (session initiated protocol) trunking. These services are offered by the majority of VoIP providers and can be tailor made to suit the needs of a small business all the way up to a large corporation with a gigantic workforce and everything in between.

    One of the main advantages of going with SIP trunking is that it will integrate everything from data, the internet, your video, and your voice services all into a single line. The term "trunking" is a bit dated and goes back to a time when traditional telephone services were used and it described how a wide variety of telephone users could share a much smaller pool of communication paths, thus making it a much more efficient option for businesses than getting a separate phone line for each worker. That was in the past, though, as today's SIP trunking capabilities will even allow all calls to be considered local calls and won't even require the business to have a single phone line at all.

    The Benefits of Using SIP Trunking Services

    Choosing to use a good SIP trunking service will significantly level the playing field for smaller business to compete with large corporations and appear much more professional and bigger than they actually are. For larger business, one of the main advantages is being able to much more easily maintain that local presence. Regardless of the size of the business itself, SIP trunking's biggest benefit overall is simply the reduction in cost to the company's overall expenses. This is particularly true for SIP VoIP services that are specifically crafted for a business in particular.
    • It offers very low cost calling.
    • It's much easier to scale than other options, making it very future proof.
    • SIP trunking makes moving a breeze, as you can easily take your phone number with you while moving offices or even while traveling.
    • Network outages are much less impactful, as incoming calls can easily be routed to other locations.
    • It's ideal for any sized business with at least 25 physical phones.
    • It's a fantastic choice for any business that has an international location.
    • It offers the same sort of emergency usages and will even offer enhanced 911 dialing options.

    How SIP Trunking Can Take Your Business To The Next Level

    It used to be that you had to have a PRI (Primary Rate Interface) in order to have video, voice, and data all on a single line. This was a physical device that had to be purchased separately but along with your chosen phone provider's calling plans. This is no longer the case with SIP, as it allows your provider to set up a proxy server (commonly referred to as a SIP proxy), which will provide the outgoing, incoming, and PBX calls for you. Everything is located off site and handled by a professional IT team or contractor through your provider, meaning it saves you a ton of time and money on the technical support side of the equation.

    Being temporarily shut down means simply having the SIP reroute calls to a different office and also allows you to much more easily outsource to international locations, such as with customer service centers.

    All of these benefits are much better than what traditional PSTN (public switched telephone network) have been able to provide through their services and will give your business just what it needs to take it to the next level. ...

  • 01/14/16--18:59: Asterisk func cut
  • Synopsis:

    at least on asterisk 1.2.8 the parameters must be separated by "|" and not ","



    • varname: variable you want cut (and not a string - see Asterisk func passthru of Asterisk 1.8)
    • delimiter: defaults to -
    • fieldspec: number of the field you want (1-based offset), may also be specified as a range (with -) or group of ranges and fields (with &).


    • The delimiter must be a single character. When multiple characters are specified, only the first character is used.
    • To specify a comma or semicolon as a delimiter, escape it with a backslash: CUT(foo,\,,1)
    • When multiple fields are specified, they are joined back together using the delimiter specified.
    • Leaving off one end of the range will give you the full variable at the field and to the other end of the variable.
      • "CUT(somevar,,3-)" would give the 3rd field and everything past,
      • "CUT(somevar,,-2)" would give the 2nd field and everything before.
    • This command is most useful when dealing with fields that are variable width. For fixed width string processing, use the builtin variable substitution.
    • CUT is frequently used to trim the uniqueid section off a channel name. For instance, the channel name might be SIP/somehost-f387 and you might want to trim that to SIP/somehost.
    • This function replaces the application Cut, which is now deprecated.

    The varname parameter must be a variable name, not a string value. This is unusual syntax. So:

    exten => s,1,Set(foo=${CUT(bar,,2)}) ; This is correct syntax
    exten => s,1,Set(foo=${CUT(${bar},,2)}) ; This is invalid syntax (unless bar contains the name of another variable)

    Return value

    Returns the resulting string.


    exten => s,1,Set(foo=1-2-3-4-5)
    exten => s,2,Set(foo=${CUT(foo,,1-3&5)})

    foo is now set to 1-2-3-5

    Cut a comma separated list:

    exten => s,1,Set(myVar="one,two,three")
    exten => s,2,Set(cutVar=${CUT(myVar,\,,1)})

    cutVar is set to value 'one'

    See also

    • Asterisk func FIELDQTY
    • Asterisk func ARRAY
    • Asterisk func POP: Removes and returns the last item off of a variable containing delimited text
    • Asterisk func SHIFT: Removes and returns the first item off of a variable containing delimited text
    • Asterisk func LISTFILTER as introduced with Asterisk 1.6.2: Remove elements from a set list (by name)
    • Asterisk func REPLACE as introduced with Asterisk 1.8
    • Asterisk func passthru: Literally pass the same argument back as its return value. The intent is to be able to use a literal string argument to functions that currently require a variable name as an argument. (Asterisk 1.8)

  • 01/14/16--22:52: Asterisk Appliances
  • An Asterisk appliance is a computer with Asterisk installed or “embedded” along with an Asterisk GUI, and FXO and FXS ports. Generally, Asterisk appliances have smaller form factors than desktops or some server models, and are highly efficient at running an Asterisk PBX.

    Asterisk appliances are useful for small businesses wanting a complete PBX that is efficient in size, performance speed, and energy usage. Asterisk appliances are less expensive than typical PBXs, ranging from $200-$1000.

    Asterisk appliances can be custom-made or pre-built from proprietary sources, or a user can build their own. Because Asterisk can run on nearly any computer, there is a wide variety of choice when it comes to the individual components of an Asterisk appliance. For example, Asterisk can be configured, depending on the modules, for 32 or 64-bit architecture. Some Asterisk appliances can use netbook chipsets such as the Intel Atom for a smaller form factor.

    When building an Asterisk appliance, compiling modules can restrict chipset and operating system. For example, the Astlinux project must use the uClibc compiler rather than the more common GCC compiler, which makes Astlinux incompatible with Digium’sG.729a codec.

    Proprietary Asterisk appliances come in many forms and do not require the user to compile code. Rhino’s Ceros uses Intel Core i3, 160GB hard drive and 1GB RAM with whatever Asterisk distribution the user chooses. The Phonebochs Telephony Appliance from Rockbochs, on the other hand, uses Intel Core Duo Mobile and Trixbox.

    Asterisk Appliance from Digium

    Digium, Inc has its own product called Asterisk Appliance 50. The server is designed for small businesses (up to 20 users) and can function as a hybrid phone solution or complete VoIP PBX.

Selecting the ideal provider and service options will depend on your type and size of business, features needed and projected volume of usage. Even when working with top-tier providers, your basic monthly service charges per line may begin at rates as low as $20. Before choosing your VoIP provider, it is essential to first determine your company's precise telecommunications needs to enable timely and cost-efficient initiation of your service.

    • Evaluate Your Internet Connection. - Determine the strength and capacity of your Internet connection and bandwidth. You need to ensure that your system has adequate speed to best accommodate your new VoIP installation for top quality service.
    • Assess Your Company Budget and Needs. - With knowledge of your company's current budget and VoIP needs, you can more easily select the service provider and feature options that meet your requirements.
    • Determine Your Equipment Needs. - Evaluate your current and near future VoIP equipment needs. Phones can be purchased from around $50 to $500 or more. Once you decide which feature options are immediate requirements and which ones can be added later as needed, you are ready to choose your service provider.
    • Compare VoIP Providers. - By comparing VoIP company service options, advanced features and equipment along with user and industry reviews, you can best make a wise decision, selecting the ideal VoIP provider for your enterprise.

    Important Information to Request from Any Potential VoIP Provider

    Before signing a service contract with any business VoIP provider, be sure to request basic service information and practices in writing. You need to be certain of such details as startup costs and monthly fees, any limitations and costs on portable phone numbers and exactly which features are included in the service package you select. You also need to know if international calling is included, charges for adding extra features and the extent of customer care and technical services provided. Also important are such issues as whether your provider offers a money back guarantee and if there are any cancellation fees. It is also helpful to determine prior to signing up for VoIP services if there are any hidden fees assessed by your chosen provider.

    Take Full Control and Advantage of Your VoIP System

    Once your new business VoIP system and service are in place, you and your staff members will have full-control capabilities for use of your business communications system. Your service provider will ensure connection with your online portal for customizing your telecomm options. These modern digital portals are user-friendly, enabling feature changes and additions to be made for immediate availability. You and your staff can make decisions and changes in real-time that work for you right in the moment.

    You can manage your call settings remotely, directing calls to voicemail or having them transferred to another number or extension. You can also make exceptions to any chosen setting in your phone system. For example, if you are expecting an important business call and want to take that call, but hold all other calls for a few hours, you can set your phone to direct only the designated call to ring on your extension. This system allows and encourages you to take complete control of your telecommunications systems and settings so that the service works for your best interests and immediate needs at all times.

  • 01/18/16--03:51: Session Border Controller
  • A Session Border Controller is a device used in select VoIP networks to exert control over the signaling and usually also the media streams involved in setting up, conducting, and tearing down calls. The SBC enforces security, quality of service and admission control mechanism over the VoIP sessions.

    The Session Border Controller is often installed in a point of demarcation between one part of a network and another. Most Session Border controllers will be installed between peering service provider networks, between the enterprise network and the service provider network, or between the service provider network and residential users.

    A Session Border Controller is like a Firewall for VOIP.
    They are often configured as a SIP Back-To-Back User Agent (See SIP RFC).

    In addition to firewall functions they also may provide services like NAT traversal.

    See: NAT and VOIP for more information and watch the video on The Anatomy of Session Border Controllers and To Couple or Decouple Routing Intelligence from SBC.

    Martyn Davies of Dialogic discusses Session Border Controllers as the often misunderstood "black magic" application for VoIP networks.

    Although carriers often use Session Border Controllers for signal translation and security, most do not include the hardware-based signal processing needed for media transcoding. For all-IP environments, new elements are required that can mediate signaling, transcode among different media formats, and handle basic security issues. The concept of Multimedia Border Element (MMBE) meets these needs.

  • 01/19/16--01:19: Asterisk config sip.conf

  • Configuration file for AsteriskSIP channels, for both inbound and outbound calls.

    Starting with Asterisk v1.2.0: The global option "port" in 1.0.X that is used to set which port to bind to has been changed to "bindport" to be more consistent with the other channel drivers and to avoid confusion with the "port" option for users/peers.

    Starting with Asterisk v1.6.0: The previously deprecated options "insecure=very" and "insecure=yes" have now been removed. "insecure=invite,port" is the equivalent of "insecure=very"

    callerid="Tuomas Tammisalo" <1000>

    Asterisk as a SIP client

    In sip.conf under [general] add a register definition:

    register => user[:secret[:authuser]]@host[:port][/extension]

    register => fromuser@fromdomain:secret@host

    register => fromuser@fromdomain:secret:authuser@host:port/extension

    See also: bug 14367 with a documentation fix for 1.6.

    If you have problems with your network connection going up and down (e.g. an unreliable cable connection) and you keep losing your sip registry, you may want to add registerattempts and registertimeout settings to the general section above the register definitions. Setting registerattempts=0 will force Asterisk to attempt to reregister until it can (the default is 10 tries). registertimeout sets the length of time in seconds between registration attempts (the default is 20 seconds).

    In case of DynDNS issues, for example with changing its IP, you might want to consider taking a look at ddclient to automate a "sip reload" in the CLI.

    P.S. Note for users: /extension must be your sipgate number (this is not true; I am using "99" --jrc) - define one to accept this in your extensions.conf. An alternate port does not seem to work with unless it is defined as the bindport in sip.conf without the [:port] syntax. ...

  • 01/19/16--16:49: Virtual PBX providers
  • Virtual BPX is a service offering functionality of a PBX without the need to install switching equipment at the customer location. Only VOIP phones need to be installed at the customer site. This makes supporting distributed workers very easy as each requires only and internet connection and a VOIP phone. A business virtual PBX phone system can reduce your monthly phone bill significantly compared to a traditional business phone system.

    What Is a Virtual PBX?

    A PBX, short for private branch exchange, is a telephone system with the capacity to switch calls between different users on local lines while still relying on the same number of external phone lines. With a virtual PBX system, the system is posted and software based without all of the traditional hardware of a physical PBX.

    Virtual PBX Primary Function

    A virtual PBX is used by businesses in a variety of ways. Primarily, companies utilize the system as an auto-attendant to establish preset call transfer options without needing an operator or receptionist. This type of system is capable of performing tasks that include auto-attendant settings, time of day or day of week functions, or even find or follow me sequences.

    One of the most important functions of a virtual PBX system for companies is the software’s ability to establish pre-determined sequences. For example, in some businesses it may be appropriate for the phone to ring to a receptionist or operator first. If the receptionist does not answer in a predetermined number of rings, however, the call is then transferred to a secretary. Again, if the call is unanswered, it can be set to forward to an assistant. Left unanswered by these two individuals, the call can be forward to a manager or even an owner. These call settings are completely customizable and can be based on any number of sequences.

    This type of software is also able to facilitate customized answering menus and sub-menus. The system can be modified to establish appropriate dial prompts leading to a number of different departments within the business, including different sequences on different days. PBXs are used by the vast majority of businesses to establish advanced call routing services.

    Virtual PBX Cost

    A virtual PBX is a complex service; however, that doesn’t mean that it is expensive. In fact, a virtual PBX is typically more cost effective than a physical PBX. The main reason that a virtual system saves on cost is that it does not require the same investment in capital to establish or set-up the call system. Because a virtual PBX is a software or hosted system, it is typically an operational cost, or a low monthly payment rather than a large upfront investment. This aspect alone generally makes a virtual or hosted PBX a less expensive, or at least more cost effective, option compared to the traditional PBX.

    Virtual PBX Benefits

    Aside from offering an effective call system, a virtual PBX presents a number of added benefits for users. As a whole, virtual PBXs lead the industry in business communication choices. This type of system seamlessly integrates the call management system with any existing phones to affordably and effectively deliver better call management. These systems also feature several innovative call features to meet the needs of any business. These systems offer various functions including call routing, follow and find me call forwarding, voicemail notifications, call recording, and more.

    The benefits aren’t limited to the features, though. Virtual PBXs offer virtually limitless application for one or hundreds and even thousands of employees. Likewise, there is not hardware to maintain or constantly upgrade. Considering that benefit, the system is also more cost effective and generally provides for a variety of flexible billing options. The limited maintenance, web-based management, and hassle-free setup alone are often enough to convince a company to switch over to this option.

    PBXs are an important tool in any business that makes and receives nearly any volume of calls. A virtual PBX can dramatically increase the efficiency of a business by effectively managing calls. This efficiency combined with the other numerous benefits of a virtual PBX can virtually transfer the communication capabilities of any company.

  • Asterisk and fax calls

    Fax over IP

    Across the Internet even a G.711 codec fax transmission is unpredictable. An excellent discussion of why faxing and modems don't work well over VoIP can be found here. However, people often get perfectly good results on lightly loaded LANs. It still isn't perfect, as a burst of data on the LAN can still upset things, but some people get results they can live with.
