[asterisk-users] Two Connected Servers Sound Quailty

[Matt Gardner]

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.
