  • 02/10/17--13:17: T.38
  • T.38 is an ITU standard for sending FAX across IP networks in a real-time mode.
    FAX messages are sent as UDP or TCP/IP packets.

    • The IETFRFCRFC 3362 implements a media type called image/t38 for T.38 faxes.

    From RFC 3362:

    ITU-T Recommendation T.38 T.38 describes the technical features necessary to transfer facsimile documents in real-time between two standard Group 3 facsimile terminals over the Internet or other networks using IP protocols. The Recommendation allows the use of either TCP or UDP depending on the service environment.

    ITU-T Recommendation T.38 T.38 Annex D describes system level requirements and procedures for internet aware facsimile implementations and internet aware facsimile gateways conforming to ITU-T T.38 to establish calls with other ITU-T T.38 implementations using the procedures defined in IETF RFC 2543 SIP-99 and IETF RFC 2327 SDP.

    Note that ITU-T T.38 Recommendation T.38 (04/02) T.38 is an aggregation of the original ITU-T Recommendation T.38 (06/98)T.38-98 and all of the subsequent Amendments and Corrigendum including T.38D-00. While T.38 and T.38D-00 describe SIP procedures per SIP-99, the procedures can also be applied to the revised Session Initiation Protocol specification SIP.

    The Importance of T.30 ECM Error Correction Mode (ECM) in T.38 Deployments

    One of the most important features of the traditional facsimile standard (T.30) is ECM error correction. The inventors of fax recognized that the audio quality of PSTN phone lines could not be trusted to be 100% error free - it was not uncommon to hear static, or the occasional pop or crackle on some fax calls. ECM error correction allows the sending and receiving terminals to compare notes at the end of each page, and selectively retransmit any data that was not received the first time around. This retransmission process is continued until the received page is certified error free, and the transmission of the next page begins.

    Remarkably, many T.38 implementations, including those of top tier carriers such as Level3, XO, Verizon etc have explicitly disabled ECM error correction. This problem is discussed in detail here. Don't make this mistake! Be sure to enable ECM and insist your provider or PBX vendor do the same!

    Want to check to make sure you have ECM enabled? This handy ECM self-test tool can tell you in minutes.

  • 02/13/17--13:16: ICD
  • Asterisk ICD

    Asterisk ICD (Intelligent Call Distribution) is an advanced mechanism for handling queues, conferences and agents and provides a unified API for interfacing to external dialer systems.

    The goal of this application is to provide a flexible, thread-safe infrastructure to the Asterisk PBX for distributing calls. that is robust and customizable for larger scale deployments.
    ICD maintains a Finite State Machine for each call. Each state is managed by a pointer to a function so each state can execute a custom function, this architecture is really designed for call center developers that want to build customized call routing strategies that fit into a standard frame work.

    There are two major components to this system, the application itself and the infrastructure pieces that support the functionality of the application.

    ICD handles queueing differently than the normal asterisk queuing system. Queues are defined in configuration files, the dialplan defines customers and agents access to the queues and in which way they are being bridged to the queue.
    Agents can for example be dynamically connected to queues on login so you could for example have a queue without members, a defined agent without a queue and connect him to a queue on login.
    Customers can also maintain their place in line and request a callbacks with out waiting inline.

    ICD is now integrated into CallWeaver as the standard agent and queue system as of Jan 1, 2008

    Installation instructions can be found in the file "README"
    Architecture info is found in "modules.txt".

    This is a work in progress

  • 02/13/17--13:17: H.263-Sorenson
  • Sorenson Spark is an implementation of H.263 for use in Flash Video and Adobe Flash files. FFmpeg uses FLV1 FourCC and Adobe frame identifiers of 0x21, 0x22 and 0x23.

    As Apple began to embrace MPEG-4 and move away from other proprietary codecs, Sorenson Media licensed Sorenson Spark (Sorenson H.263) to Macromedia, which was included with Macromedia Flash MX v6 on March 4, 2002. Sorenson Spark is the required video compression format for Flash Player 6 and 7.

    Macromedia later tried to find a better video codec. Starting with Flash Player 8 (released in September 2005), the preferred video codec became VP6. Sorenson Spark can be still used in the Adobe Flash CS4 Professional (2008) for Flash Video files (alongside H.264 and VP6).[17] According to Adobe engineer Tinic Uro, Sorenson Spark is an incomplete implementation of H.263. It differs mostly in header structure and ranges of the coefficients.

    FFmpeg in 2003 added encoding and decoding support for Sorenson H.263.
    Asterisk can support it with the chan_rtmp developped by ulex.

  • 02/13/17--20:58: Asterisk at large
  • Planning a large installation with SER or OpenSER

    Improving performance

    • Store the voice prompts in RAM instead of harddisk: Take a look at ramfs. All you need then is to create a link (ln -s) in /var/lib/asterisk/sound to then ramdrive you created using ramfs.
    • add "fs.file-max = 131072" to /etc/sysctl.conf - run "sysctl -p"
    • add "ulimit -n32768" to /etc/init.d/asterisk

    SIP proxy before Asterisk (e.g. SER)

    SER is a very capable SIP router, much more sophisticated than Asterisk as it can look inside packets and route based on what it finds or even re-write packets based on user specified logic.

    Howto: Getting to know SER

    If you want a good explaination of SER and how to use it start here:
    Latest Guide
    Old Guide
    They have GREAT pre-written configs and walk you through every part of SER. I was about to scrap SER before I found these tutorials.

    And then there's the OpenSER documentation on how to integrate with Asterisk in realtime for VoiceMail and MWI. Find even more on the same topic here.

    Asterisk, OpenSER and mediaproxy in a WAN environment

    Asterisk, OpenSER and WAN
    This article discusses some of the problems encountered with OpenSER and Asterisk features when implementing a Enterprise VOIP system - and how to solve them.

    Benefits for Asterisk

    We are using both, SER and Asterisk, in heavy production environment. SER is the BEST SIP proxy that i found. But it is just sip proxy. It can serve a _LOT_ connections (10,000 users, 20 cals per second). Asterisk is more like telephone switch with lot of features, but far slower.

    One nice feature of SER is that users can set up their own SIP accounts using a web interface and not needing to edit *.conf files.

    Q: In a large installation (many users) - how do you off-load Asterisk by managing RTP traffic effectively?
    A: There's no single truth here, but here's my opinion:

    • If you are all on the same internal network, make sure the SIP phones support re-invites and use that.
    • If you have users all over the Internet, use a SIP proxy (like SER) as a front-end to Asterisk. You will still be forced to handle a lot of RTP streams (because of NAT), but can distribute that over a SIP-proxy network with SRV records, DNS round-robin techniques or forcing the users to register with different proxies.

    Example: FWD and SIPGATE both run SER coupled with Asterisk

    There's been a couple of suggestions that we should make Asterisk a good SIP proxy. If you spend some time learning to understand Asterisk's architecture, you'll also understand that this would not really work. I'm not saying the SIP channel can't be improved, I'm just saying that it has to work with the rest of Asterisk's architecture. Asterisk in combination with a separate SIP proxy is a very powerful solution. ...

    valid for kamailio (openser) 1.5.x and asterisk 1.4.x — work in progress

    • latest release in 1.5.1 series of Kamailio (OpenSER) is v1.5.1
    • latest release in 1.4 series of Asterisk is v1.4.24.1

    Kamailio is a pure VoIP signaling server using Session Initiation Protocol - SIP. It is flexible and highly configurable but cannot be used to provide media services as voicemail, announcements or conferencing. For such services, Asterisk is the most suitable open source product. In this document we present how to configure Asterisk to use Kamailio's subscribers database to provide voicemail service. A basic configuration file for Kamailio is posted down the page, allowing to have a functional system by following the steps in this tutorial.


    UnixODBC Installation

    Install unixodbc-dev package via your package manager. Alternative is to get the sources from, compile and install them on your system, but Asterisk will have hard time to detect them and enable ODBC option for Voicemail application.

    In Debian:

    apt-get install unixodbc-dev

    MySQL Installation

    You can install MySQL using the packaging system from you Linux distribution. The only requirements is to be MySQL 5.0+. Most of the distributions deliver v5.0+ by default now.

    After installation, you can set the MySQL root password with a command like:
    /usr/bin/mysqladmin -u root password 'your-new-password'

    Asterisk Installation

    Get Asterisk sources from At this moment Asterisk 1.4.22 is the latest stable version.

  • 02/14/17--10:46: GSM Codec
  • GSM (Global System for Mobile communications) is a cellular phone system standard popular outside the USA. You can find more info on GSM in general here

    GSM includes a codec, often just referred to as the GSM when discussing codecs.

    The original 'Full Rate' GSM speech codec is named RPE-LTP (Regular Pulse Excitation Long-Term Prediction). This codec uses the information from previous samples (this information does not change very quickly) in order to predict the current sample. The speech signal is divided into blocks of 20 ms. These blocks are then passed to the speech codec, which has a rate of 13 kbps, in order to obtain blocks of 260 bits. You can compare GSM cell phone plans using Wirefly.

    Newer GSM systems use a couple of newer codecs however these are heavily patent encumbered:

    • EFR (Enhanced Full Rate) uses ACELP (Algebraic Code Excited Linear Prediction)
    • HR (Half Rate) uses CELP-VSELP (Code Excited Linear Prediction - Vector Sum Excited Linear Prediction)

    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.

  • 02/15/17--08:17: Virtual PBX
  • Virtual PBX is a budget-friendly form of hosted VoIP (Voice over Internet Protocol) that usually only handles inbound calls. A virtual PBX is typically intended for small business VoIP customers with fewer than 10 employees and low-volume telephone traffic.

    What Is Virtual PBX?

    A virtual PBX is an economy-class version of hosted PBX. Hosted and virtual PBX systems are business VoIP PBX phone systems that transmit calls over the Internet as data.

    A virtual PBX offers inexpensive business VoIP telephone service to small businesses. As with a hosted PBX phone systems, a virtual PBX is owned and maintained off-site by a VoIP service provider. A virtual PBX enables a small business telephone system to access enterprise-level features such as auto attendants and voicemail. With virtual PBX small business telephone systems, small start-ups, mom-and-pop shops, freelancers, and entrepreneurs can all present a professional image to vendors, investors, and customers.

    Depending on the service provider, a virtual PBX phone system may require a separate phone service for outbound calls.

    Virtual PBX Features

    Virtual PBX phone systems offer lower costs and fewer features than hosted PBX phone services. Compared to hosted PBX small business telephone systems, virtual PBX service is limited to the most basic fundamentals of business-oriented call controls. Virtual PBX is geared toward simple inbound call-routing for SoHo offices with few personnel, small budgets, and limited calling needs. As with many hosted PBX calling services, most virtual PBX phone systems do not require a contract or term commitment.

    Standard features offered with most virtual PBX plans are:

    • Voicemail
    • Auto attendant
    • Unlimited call handling (no busy signals)
    • Call forwarding


    Virtual PBX phone systems generally:

    • Handle only inbound calls
    • Offer a limited number of extensions
    • May not include Fax over IP (FoIP) services
    • Include a set amount of free minutes
    • May not offer voicemail-to-email
    • May not include international long-distance coverage
    • May not offer Internet fax service
    • May charge extra for conference calling

    The features offered vary by virtual PBX VoIP provider. As VoIP service becomes a more common solution for small business telephone systems, many virtual PBX plan features are incorporating the more advanced features of hosted PBX phone systems. Compare plans and prices to determine the best virtual PBX solution.


    Virtual PBX phone prices depend on a variety of factors, such as the features included. Virtual PBX phone service plans can start as low as $9.95 (Grasshopper) per month.

  • 02/22/17--09:26: VoIP Service for Schools
  • In schools, effective communication is essential for assisting administrators in managing the learning environment, helping teachers deliver quality education, and providing accurate information that can nurture the minds of students. Through a reliable phone solution like VoIP, administrators can provide students and teachers with the best communication tools they need to improve the learning process and to achieve success.

    Whether you're searching for a reputable VoIP provider in your area or are looking for authentic user-submitted reviews on VoIP services, Voip-Info can provide you with relevant and helpful information on various VoIP phone solutions for schools. You can search our site for tips, configurations, software, hardware, and guidelines while also visiting our VoIP forums to help make your transition to VoIP smooth and easy.

    How Can Schools Benefit from Using VoIP?

    A VoIP phone system is a dynamic communication platform that can help improve the learning process and enhance the safety of students, teachers, and faculty members.

    Schools need a reliable phone system with handy features to make communication accessible for teachers, staff members, parents, and students. Through an efficient communication solution like VoIP, schools can improve their mobility and productivity, build stronger teacher-student relationships, and enhance the overall learning experience.

    VoIP features such as voicemail, instant messaging, and video conferencing can make collaboration easier for teachers, outside field experts, and students. Through video conferencing, students can go on virtual tours to enhance their knowledge on certain subjects. Students can also work with other students (from different schools) or talk to field experts without leaving the school campus.

    Also, using a VoIP phone system can improve teacher-parent relationships. Through a VoIP phone solution, teachers can pick up e-mail messages or listen to voicemail over a mobile phone and then send a message or response to parents. Features such as hunt groups, call routing, and find me/follow me can also enable teachers to answer calls from parents even when they are off campus. This way, parents can easily keep track of their children's performance in the classroom and teachers can respond to inquiries in real-time.

    Additionally, a VoIP phone system enables teachers to communicate with students and outside field experts remotely. Because of this, teachers do not need to use a physical room or special network during a discussion or training because a virtual classroom can be established via mobile phones, desktops, tablets, laptops, and other devices.

    Plus, with the use of the call recording feature, students can listen to lectures in a virtual setting. They can easily record calls and store them in an audio format, and then use these files during study groups and mentoring programs. In this way, students can expand their knowledge and enhance their educational experiences.

    How Can VoIP Increase School Safety and Security?

    A robust VoIP system can help administrators to better manage their schools and to build safer learning environments for students, teachers, and other personnel.

    With the use of a VoIP phone system, school administrators can make the learning environment safer and more secure. One great way to enhance the safety and security of students, teachers, and other personnel inside the school campus is to integrate an emergency notification system. By making use of a VoIP-enabled emergency notification system, schools can increase their ability to manage any potential threats. With the help of this system, schools can immediately alert authorities to potentially dangerous situations.

    Aside from this, using instant messaging and group paging features of VoIP, administrators can also help notify students, teachers, and other school personnel during emergencies by sending messages to their desk phones or email. This way, school administrators can communicate with students, teachers, and staff members even when there is a power outage.

    Additionally, advanced VoIP features such as group paging can heighten school security because a single call can alert all offices and classrooms. Through this function, school administrators can page students, teachers, and other personnel by pre-programming a set of extension numbers and then dialing one extension number. In this way, administrators can relay messages or broadcast announcements throughout the entire campus to alert students, teachers, and staff members in case of an emergency. ...
