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:
...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

Try the patch from https://issues.asterisk.org/view.php?id=15896. It should apply ok on

Nice, problem solved - thanks ebroad.

Might want to add this as a relationship to 15896 as it makes no reference to having anything to do with unreachable TCP peers...

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.

This issue can be closed once the child issue has been closed. Thanks!

Since the child has now been fixed I am closing this out.
