Installing Digium g.729 codec for Asterisk on an OpenVZ VPS. This is because the installation routine relies on there being an ‘eth0’ device on the server. This is not normally the case with OpenVZ where the network device is called venet0. An ‘eth0’ device can be created on the VPS by running the following command (this is done on the OpenVZ server). Enabling codecs in modules.conf.xml. Codecs are built from various modules and from the core FreeSWITCH source (no need to load modules for core codecs, they are in CORE_PCM_MODULE, e.g. They're built into the core of FreeSWITCH). For codecs not in core, you need to compile and load the corresponding module. The Asterisk box is negotiating payload 97 for ilbc codec.The problem with this is that this is a pre-configured payload type on cisco gateways as 'cisco-codec-fax-ack' You need to change the payload type for 97 on the router.

Internet Low Bitrate Codec (iLBC) is an open-sourceroyalty-freenarrowbandspeechaudio coding formatcodec and reference implementation, developed by Global IP Solutions (GIPS) formerly Global IP Sound (acquired by Google Inc in 2011^[2]). It was formerly freeware with limitations on commercial use,^[3][4] but since 2011 it is available under a free software/open source (3-clause BSD license) license as a part of the open source WebRTC project.^[5] It is suitable for VoIP applications, streaming audio, archival and messaging. The algorithm is a version of block-independent linear predictive coding, with the choice of data frame lengths of 20 and 30 milliseconds. The encoded blocks have to be encapsulated in a suitable protocol for transport, usually the Real-time Transport Protocol (RTP).

iLBC handles lost frames through graceful speech quality degradation. Lost frames often occur in connection with lost or delayed IP packets. Ordinary low-bitrate codecs exploit dependencies between speech frames, which cause errors to propagate when packets are lost or delayed. In contrast, iLBC-encoded speech frames are independent and so this problem will not occur.

iLBC is defined in RFC 3951. It is one of the codecs used by Gizmo5, WebRTC, Ekiga, Google Talk, Maemo Recorder (on the Nokia N800/N810), Polycom IP Phone, Cisco, QuteCom, Tuenti,^[6]Yahoo! Messenger, Ooma^[7] and many others.

iLBC was submitted to IETF in 2002^[8][9] and the final specification was published in 2004.

Parameters and features[edit]

• Sampling frequency 8 kHz/16 bit (160 samples for 20 ms frames, 240 samples for 30 ms frames)
• Controlled response to packet loss, delay and jitter
• Fixed bitrate (15.2 kbit/s for 20 ms frames, 13.33 kbit/s for 30 ms frames)
• Fixed frame size (304 bits per block for 20 ms frames, 400 bits per block for 30 ms frames)
• Robustness similar to pulse code modulation (PCM) with packet loss concealment, like the ITU-T G.711
• CPU load similar to G.729A, with higher basic quality and better response to packet loss
• Since 2011 it is available under an open source (3-clause BSD license) license as a part of the open source WebRTC project.^[5] (previously commercial use of the source code supplied by GIPS required a licence^[10])
• PSQM testing under ideal conditions yields mean opinion scores of 4.14 for iLBC (15.2 kbit/s), compared to 4.3 for G.711 (µ-law)

i am developing a SIP application for making and receiving a call and i want to add the G729 codec in my application.

currently i am doing analysis on open source project SipDroid. if i want to make that application to support G729 codec how to do that?

there is a different codecs configuration file in org.sipdroid.codecs package.how do create the this kind of .java file for G729 codec?

Any suggestion and response will be appreciated.

your asterisk logs looks pretty good to support the codec, but you need the g729 encoder on your client android application (seems to be a commercial license for now), please let me know if you have any luck on getting an opensource license of the codec.
