Summary:                    SIP/TCP always shows registered peer as UNREACHABLE
Description: 
Any peers using protocol SIP/TCP are always marked as UNREACHABLE, no
matter what.

Replicatable 100% even with different CPE's.
Problem always goes away when using UDP.

Have tried:
transport=tcp
transport=tcp,udp
transport=udp,tcp
...all report the same, unreachable


This also affects dundi lookups ie asterisk will not return any result due
to thinking peer is not registered, but it is.

There are a few earlier bugs relating to this - I think some earlier
patches may have re-introduced the problem.

This applies to public release, latest version 1.6.1.6.

You welcome! The issue is actually a bigger issue in the fact that when
using TCP/TLS we return from handle_response() before doing anything, so a
response to a peer_poke() will never get handled.
