[asterisk-users] Two Connected Servers Sound Quailty

[Thomas Deillon]

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

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.
