? I'm sorry that I'm not capable of remembering stuff across threads, I tend 
to mix up.
However, not using t_relay  because you use mediaproxy doesn't make any 
sense to me. It's in route[1]?!

Yes, same effect... Just executed more often ;-)

Yes, that's true. The trying is auto-generated by ser.  A quick-fix would be 
to add:
sl_send_reply("100","trying...");
for all Cisco invites.  You would still get the 5060 auto-generated one, but 
at least the box will get its trying...
