RE: [Iaxclient-devel] codecs.

[Richard P. <ric...@co...>]

It would seem that the problem I'm having at the moment is with our asterisk
box.

I apologize for the false alarm =)

Thanks for your help!

Cheers
	Richard

I wasn't sure about what the sample variable does. I found that I got more
distortion when I played around with it so I figured that it could also
reduce the distortion if it was set up differently. I was probably way off
base with that...

I get the distortion on both gsm and ulaw if I set them in IAX using
iaxc_set_encode_format

Cheers

So, I've done just a very limited amount of testing so far with this new
code:

1) Did a test from my mac to PSTN via nufone and uLaw:  worked fine.
2) Did a test from my linux PC to PSTN via local asterisk and GSM:
worked fine.

So, there certainly might be issues that I'm not seeing here.

"sample variable of the packet not being set correctly?"

Do you mean the samples item in IAX2?  I didn't know it was set wrong?
Did you see this in ethereal?
