[asterisk-bugs] [JIRA] (ASTERISK-27147) Either asterisk or pjproject isn't re-using tcp connections (again)

Richard Mudgett commented on ASTERISK-27147:
--------------------------------------------

[~rossbeer] Yes the subscription will persist because it is supposed to persist even across Asterisk restarts.  Yes any subsequent notify will fail until the endpoint re-registers because there is no valid contact address.  These are two separate things.  It would be bad to cancel any subscriptions because of a temporary unreachable condition.

> Last year we submitted patches to pjproject to fix not re-using tcp connections.  It looks like it's broke again.
> Asterisk A and B have a "trunk" between them.  A registers to B.
> After A registers, there is 1 open TCP connection between them.
> B sends a call to A.
> Instead of re-using the existing connection, B establishes a new cconnection back to A.
> Now there are 2 tcp connections open.
> If A were behind a firewall that didn't allow inbound new connections, there'd be an issue.
