That is not how Asterisk works, and is well known in the community as something that users would like to see changed, but has not yet been done. Asterisk negotiates the codecs (formats) for each call leg pretty much independently of the others, so if a G.722 endpoint initiates the first call leg, and the destination call leg cannot accept G.722, and there is no transcoder available, then the call will fail. If the non-G.722 endpoint initiates the first call leg then the call will likely go through, which is somewhat unfortunate :-) -- Kevin P.
