[Rusty Newton (JIRA)]

     [ https://issues.asterisk.org/jira/browse/ASTERISK-21753?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Rusty Newton closed ASTERISK-21753.
-----------------------------------

    Resolution: Won't Fix

We are cleaning up the issue tracker.

Closing this out as there has been no movement on it for many years and it was filed against versions that are all no longer under bug fix support.

If an issue exists with a supported version of Asterisk please open a new issue and provide debug from a recent supported version. Thanks!

> Asterisk is performing pure SIP transit calls from/to an Avaya Communication Manager 5.2.1(ACM) from/to a SIP carrier (COLT).
> From an asterisk(192.168.69.9) point of view :
> - ACM(192.168.69.10) is SIP TCP PEER (as SIP UDP is not supported in this ACM release)
> - COLT(192.168.254.5 / 192.168.253.254) is a SIP UDP PEER
> directrtpsetup = yes
> This asterisk run around 300.000 calls per day
> Asterisk is crashing (seg fault) on similar SIP message (incoming SIP TCP ACK with session description, cseq = "2 ACK", from ACM).
> Crash frequency : between 0-2 per day.
> I can't reproduce the issue (i've generated with sipp the same scenario, it doesn't crash)
> I'm providing two exemples (11.3.0 bt, pcap file)
