Hi...quick question:
If i'm trying to setup a call between 2 3640's and one of them is running a codec with a-law on it and the other with u-law, will it work? (i;m almost expecting the answer to be NO) why not?
If the answer is NO: then why would the calls work one-way (from a-law to u-law) but not the other way around?

Hi Carlos,
you must have the same codec in the common dial-peers between the routers.

You can also setup a voice class for the codec. These come in handy when you have more than one codec being used in the network. Here is a link on how you configure it.

Okey just another qucik question. What if i want to create such voice class thing for POTS dial-peer. I mean to say if someone dials with any codec and i want to match it on my terminating Access Server ?. I have many different vendors using different codec, terminating calls on us. Any suggestions

voice class apply to VoIP dial-peer both inbound and out bound. When you create a voice class with a list of codec, if some vendors they want to terninate the calls to you, his codec much match with your list.
