I am developing Softphone dialer applications for android, iOS etc with PJSIP. I need to know how to integrate G.729 Codec with the project. I've seen articles related to building G.729 Codec using Intel IPP in PJSIP Website itself. But when I contacted Intel Support Team, they told me that it was only supported in older versions of IPP. Now they are not supporting arm processors and G.729 Codec is also not coming along with the sample project. Is there any other way to integrate the codec with PJSIP project.
G 729 and G 711 are voice-over-internet-protocol (VoIP) phone codecs, which are programs that compress the sound of your voice for easier transmission during an internet phone call, decompressing it on the other end.

I had the same requirement for one of my VOIP app. But haven't found any solution or stack overflow answer for a long. So finally i come to know there is another open source 'linphone'(not pjsip stack) integrated with g729codec.
So i took the g729 codec library alone from linphone and created a patch for pjsip. Also I have tested with my iOS app it works well. You can download the patches from my git repo https://github.com/saravanandm/pjsip-g729codec

First you need to download g729 patch from pjsip-android-builder library https://github.com/VoiSmart/pjsip-android-builder/tree/master/g729_patch
Download pjsip , unzip it; put g729_patch folder and pjsip folder into one folder.In g729_patch open in editor install.sh and edit the line 5 (put the correct name of your folder with pjsip), for me it was:PJPROJECT_BASE_FOLDER='./pjproject-2.7.2'
In terminal cd to g729_patch directory and run ./install.sh (you need autoconf utility to be installed for that); patch can be applied manually as well, see instructions in readme.
Create file config_site.h with the following content:
for me it was for android but can be for other platform so 1st line can vary, also other options can be added.Put this file to /pjlib/include/pj.
cd to your pjsip directory and run:
![G 711 codec G 711 codec](https://www.zoiper.com/images/support/z_andr_audio_codecs.png)
./configure-android --enable-g729-codec
for me it was android so i ran ./configure-android but may be other.on this step any other configure flags can be applied, for example for me it wasNDK_TOOLCHAIN_VERSION=4.9 TARGET_ABI=armeabi-v7a ./configure-android --use-ndk-cflags --enable-g729-codec
then run:
![Codec Codec](https://avanzada7.com/en/imagen-producto/2-g729codec.jpg)
make dep && make clean && make
That's it - pjsip is compiled with g729 codec.

For me using IPP would be overkill. AFAIR it is also not free.
Use GSM codec module as a template, modify it and add open source G.729/a (asterisk, freeswitch) implementation as third party library.

You might have a look at CSipSimple project (https://code.google.com/p/csipsimple/), they use pjsua and G729 codec can be included into the application.
