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

[Ross Beer (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-27147?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=238041#comment-238041 ] 

Ross Beer commented on ASTERISK-27147:
--------------------------------------

If the phone goes offline for some other reason and stays offline, won't the BLF/MWI persist?

When a voicemail is left or BLF state change happen, wouldn't Asterisk attempt to contact the endpoint in the same way as calling the endpoint would? This would fail as per the above description.

> 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.
