Ok so If Freeswitch isn't in the media path and you still have robotic sounding audio then you need to look at what remains, the UAC, UAS and the network between them.

Hello All,

Whenever i am trying to make a call, Two way commnunication was established but I am having kind of choppy like robotic voice or very bad quality of voice with only G729 codec.For PCMU,PCMA both are working fine.I want to work with G729.
I have set below parameters in sip profile to try to resolve this issue. But it doesn't work for me.

aggressive-nat-detection : true
absolute_codec_string : G729
inbound-codec-prefs :G729,PCMU,PCMA
outbound-codec-prefs : G729,PCMU,PCMA
inbound-late-negotiation :true
inbound-codec-negotiation : generous

Any help and ideas will be appreciated.

FYI : For debug purpose you may get  SIP Log from http://pastebin.com/D2cPLJWe
