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.
