I see you still call it when you have the to_tag. Even more you call it 
for every method, not just INVITE.

Make sure you have the mediaproxy dispatcher running on the same host as 
opensips, and at least one mediaproxy relay running (the relay doesn't 
necessarily have to run on the same machine).
/var/run/mediaproxy/dispatcher.sock should be visible for opensips.
