Hi ,
I am getting the call connected and got 200 ok from the client . But the
INVITE packet goes multiple times between terminating pcscf and s-cscf and
gives too many hops error .Even After that call goes perfectly fine with
200 ok message.
What would be the reason . I am not getting any errors in my logs with
debug log level 6 .
Kindly tell me what could be the issue .

That usually happens when you don’t set a next
hop, or destination
where the packet should go, so the packet of forwarded to the same
destination, which is the proxy again.
