b) Please check the issue tacker to avoid duplication
c) Please provide network capture (wireshark) or Android log (DDMS output)
if you want quick response

What steps will reproduce the problem?
1. Install IMSDroid-2.548.870.apk on LG L5 and Orange Luno handsets.
2. Register into Kamailio+Asterisk server.
3. Make an audio call (to an outside line), using G.729 codec. Make an audio 
call (to an outside line), using G.711 codec.

What is the expected output? What do you see instead?
Listen audio correctly in both sides is expected, but it only happens in caller 
side. Sound on IMSDroid side is good, but on the outside is not acceptable at 
all, very choppy and with a lot of echo. We made our tests in both Wi-Fi and 3G 
networks.

What version of the product are you using? On what operating system?
We are using IMSDroid-2.548.870 in Android 4.x S.O. This IMSDroid version is 
the one we achieved the best results with on LG L5 and Orange Luno devices. If 
we install an IMSDroid version compiled with last version of doubango 
libraries, results are even worst.

Please provide any additional information below.
Our system lets users register in a Kamailio+Asterisk server and place SIP 
calls. Asterisk send these calls to an outside line, so only caller side is a 
soft phone. Most of devices we have tested worked fine with both 
IMSDroid-2.548.870 and IMSDroid compiled with last doubango libraries version, 
but not in LG L5 and Orange Luno. We tested Indoona app (based in doubango 
libraries), in these two devices and we obtained the same results. However, 
other soft phones like Libon or Rebtel worked fine on these handsets.

I attach network capture o several calls with IMSDroid-2.548.870.apk, using 
both G.729 and G.711 codecs.

Any advise?

Thanks
