[Asterisk-Users] RE: Teliax - Codec Preference effective?

[Brent Torrenga]

Thanks for your input, everyone, but I still think it is on Teliax's end...
I will present our collective thoughts to their tech.

Kevin,
I am using IAX. When I turn on IAX debug, I get:

I don't see any codec negotiation stuff other than my end requesting g726...
The only "effective" codec I get is GSM, which is my old setting on the
Teliax site.

Marty,
Hehehe, yes, I did realize this "feature" on the web page - it is subtle
though.

Ross,
Yeah, good point. Once I do get this straightened out I will just enable
everything on their end and pick and choose with my * box at my end. So, I
guess the only reason I need to set it on their end is to cause me
trouble...?

g729.  I didn't set anything in the Teliax >control panel, I just set
everything on the Asterisk box; works great for me.
