<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">This patch adds a peer configuration property 'override_codecs' (better name suggestions welcome of course) that allows the peer's configured 'allowed' codecs to be listed first on an outgoing call. If the codec for the initiating request is not already listed in the peer's configuration, it is listed after the peer's listed codecs. The consequence is that Asterisk's usual efforts to prefer avoiding transcoding can be overridden on a peer-by-peer basis where appropriate. Undoubtedly a "use-with-caution" feature.</pre>

Peer A -> Asterisk Host A -> Asterisk Host B (with patch applied) -> Peer B
Peer A is configured to use ulaw in Host A's sip.conf, Peer B is configured with:

allow=ulaw

Media from Peer A to Host A and Host A to Host B is in ulaw where the invite from Host B to Peer B specifies alaw. Media from Host B to Peer B proceeds with alaw.</pre>
