Have you tried ulaw yet? With 512 and a t1, you have more than enough bandwidth for a few streams with that codec. One wouldn't be a problem. Also, check to make sure the entire path is a single codec, I have run into an issue before ( when I first started playing with * as a matter of fact ), where I was going from gsm, to ulaw to alaw ( long story ) back to gsm. Voice quality sucked, obviously, because I was doing all sorts of conversions. Keep yourself to a single codec, preferrably ulaw/alaw, and you should be fine.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
Also check for iax timing, that could cause issues as well.
TOS is a quality of service bit on the packets in the stream, they don't do anything by themselves. Instead, any switches/routers than understand it will push those packets to their appropriate position in the queue based on the TOS value.
I'm not entirely clear on what jitter is either, but it's never been important enough for me to go digging. Anybody have any insight here?
