dear,
I'm working on a project and i'm using ser as a sip server.
 actually i have this problem: every time i send an instant message to
 a subscriber i get this error message:
483 too many hops
i tried to fix it but i couldn't and i don't know what to do !
(My computer connect many computers. Is it reason?!)
if any one can help me i'll be very grateful
i'm using ser 0.9.3
When I use sipsak,
I received following messages.
root]# sipsak -T -s sip:user@mydomain.com
