[Spce-user] 483 Too Many Hops

[Lorenzo Mangani]

Hi Marc,

As you can see from your trace, the call is never completely established,
as the 200 OK's ACK never makes it back to the user-agent.
After a brief look this seems to be caused by the gateway always using the
contact header to respond instead of the from header, as for the BYE
message also being rejected for the same reason - just my 2 cents, might be
wrong - maybe someone else on the list will have different input,

Best,

Lorenzo Mangani
