G.723 is different from G.711,G729  it uses 30 msec. not standard 20 msec
audio slots you may need to change this config in set B

Subject: [SIPForum-discussion] audio problem with G.723, B party can hear
properly but A party cannot

 

Hi,

 

I am trying one interconnection where i tested calls with G.729 and G.711
and the calls were successful with good voice quality but if i use G.723 and
make a call, then the B Party is able to hear A properly but the B party
gets choppy voice.

 

If i try G.723 calls with other providers i am not facing this issue.

 

In this trace i can see in the RTP summary that from A to B there is a
packet loss of 99% whereas B to A is 0%, but there are other cases when this
loss on both sides was 0% then also I faced voice quality problem for audio
coming from B to A.

 

Can Someone throw a light here.

 

Thanks & Regards

Prakash Singh Chaudhary
