[Asterisk-Users] Voice Quality

[david at ccds.ca]

Hello,

I have setup two * servers and they are communicating using IAX. I'm
passing calls from SRV A (internet connection T1) to SRV B (internet
connection: 512).

For some reasons I have an issue with the quality. The voice is a bit
scratchy. I have tried iLBC and SPEEX, but it didn't make any difference.

Now, assuming that I have an issue with Bandwidth, what would be the best
way to configure my iax.conf. (A bit confused about jitterbuffer and tos)

Here is my iax.conf @ location A:

[general]
port=4569
bandwidth=low
disallow=all
allow=ilbc
;allow=ulaw
;allow=speex
jitterbuffer=200
jitterbuffer=yes
tos=lowdelay

and iax.conf @ location B:

[general]
port=4569
bandwidth=low
disallow=all
allow=ilbc
;allow=ulaw
;allow=speex
jitterbuffer=200
jitterbuffer=yes
tos=lowdelay

[guest]
type=user
context=default
callerid="Guest IAX User"
disallow=all
allow=ilbc


Thanks guys
