[asterisk-bugs] [JIRA] (ASTERISK-26984) chan_pjsip TLS incorrectly tears down connection

[Ross Beer (JIRA)]

     [ https://issues.asterisk.org/jira/browse/ASTERISK-26984?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Ross Beer updated ASTERISK-26984:
---------------------------------

    Description: 
chan_pjsip attempts to create sessions to closed TLS connections on incorrect ports. This leads to the eventual teardown of the connected session by Asterisk.

The attaced image shows successful communication on port 35430 and then attempted SYN packets to other ports such as 37848, 57750 etc. These packets will never reach the endpoint as these have already been closed. This can be seen in the 'TCP Retransmission' entries.

Asterisk should either attempt to use the open connection to conact the endpoing or give up trying when timing out. However, at present, Asterisk closes the active connection making the endpoint go offline.
