Hi all,

 

I have the same problem using SIP with G729 and it's just on one direction.

But ... there is bandwidth management on the FW equipment (sonicwall) and 
others clients (we are a IP centrex) works find using the same server.

 

A idea ?

 

Thomas

Objet : [asterisk-users] Two Connected Servers Sound Quailty

 

Ok this is my first post and I will try to keep it short.

 

I have searched everywhere and haven't found an answer to my question

 

I have two Trixbox servers that are connected over the Internet via an IAX2 
connection.  We are experiencing very poor sound quality.  I have tried many 
different codecs gsm, ilbc, g729, g711 and all seem to have the same problem. 
(All though g729 seems to work the best but still isn't reliable)  The problems 
are intermittent sometimes the sound will cut out for 3-4 seconds and other 
times the sound will just be loosing every other word, and other times it 
sounds just fine. 

 

Also, we have been using Skype over this same Internet connection and have very 
good sound quality with very few lost words.

 

So here are my questions.

 

First, is it a correct assumption to say that because Skype works well over 
this connection then I should be able to get asterisk to work over this 
connect.  I am hoping that Skype isn't "better" then asterisk in this area. 

 

If I should be able to get the same sound quality could you point me in the 
right direction on how to achieve this.  (I have tried messing with the 
jitterbuffer but haven't been able to find very good docs on how to utilize 
this functionality so about all I have done is set jitterbuffer=yes) 

 

Thanks in advance.
