Hi Nick,
this is not little note, this has cleared many things for me. Thanks for
that.
it means, suppose i have not got any incoming dial peer which matches any
codec, then by default call will be matched by default dial peer 0 and it
will have all the codec capabilities and then i might not need any
transcoder/resource to convert that incoming codec.
Please correct me if i m wrong.
