It seems to only allocates a single media session when use_media_proxy() is called on a SIP message with multiple branches, so when one session is established and the other is torn down, the media session with media proxy is also torn down.

if invite forks and proxy can therefore receive several 1xx replies from the branches, use_media_proxy() should recognize replies that belong to the same session and update the state of this for each reply, especially for final 2xx reply.

this is a known issue, but as far as i know, it has not been fixed yet.
