I would have some questions on Codecs…
I am using Asterisk 1.4…
If I understood correctly…
Let’s suppose that a provider using some codecs. I need to make sure that my config in SIP.conf will match all these codecs ?
-… and that My SIP phone will list the specific codec !?
Now, If I use a list of codecs, how can make sure that I will use in a specific order ?
Typically, I have a landline phone number associated to a VOIP provider.
I call my “Landline”… call another provider to make an international phone call… I could hear the person, but nobody could listen to me…
I suppose that this is codec problem ?
How could I force a specific codec with Asterisk? (and to declare it ?)
if I have :
=> Does it mean that I’ll force to use ulaw AND THEN if needed, g711 ?
Do you think that GSM codec could work with any provider ?
I’ve seen that there are some codec “translation” in Asterisk…
Could it be the possibility to translate a codec -> another one IF the codec is not supported ?
-> if so, how to configure this ?? Is that automatic ?
Thanks for your help
