This is expected behavior because sipXbridge will retransmit 180 for
every corresponding branch it receives due to the hunt group fork.
There is no SIP law broken here. Retransmitting 180 is perfectly legal.

In sipx 4.4, we have a customer (with their own SIP trunk) where a
user has set forwarding same time to a parallel hunt group with 4
members. I would expect to see one 180 from the called user and one
180 from the hunt group. Instead we are seeing a burst of a number of
180s, up to ten or more. This is causing the SIP trunk to cancel the
call. And the odd thing is that all the 180s are identical.
Any ideas? Is the hunt group supposed to give one single 180, or will
180 come from every single member of HG?
In the capture 10.100.10.106 is sipx and 193.246.242.135 is SBC with
CS2K behind.
