[Asterisk-Users] Specify Codec In Outbount Calls?

Sure, just use something like this in iax.conf:

[diamondcard]
type=peer       ; outgoing calls only
host=1.2.3.4
username=myuserid
secret=mypassword
disallow=all
allow=gsm

Then in your Dial statement, simply refer to the context.

If you're not sure how to construct that dial statement, do a
 show application dial
from the CLI. It should look something like:
 exten => _72.,3,Dial(IAX2/myuserid at diamondcard/${EXTEN:2}) 

The above is just one way to do it.
