HI to everyone:),
I need a little help. I am new to opensips, right now I am
implementing load_balancar which is for now working:)
ok, problem is when calls go from opensips to fs (fs for media
handling), fs bridge back call to opensips, which sends call to phone
(both phones are registered to opensips). After second user pickups
call, call is being canceled by opensips.
If call is send to user, which is not registered to opensips call is ok.
Thanks!
Miha
