[asterisk-bugs] [JIRA] (ASTERISK-28811) Crash occurs when fax session switches from T.38 to audio

[Alexei Gradinari (JIRA)]

     [ https://issues.asterisk.org/jira/browse/ASTERISK-28811?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Alexei Gradinari updated ASTERISK-28811:
----------------------------------------

    Attachment: fax_491.txt

[~jcolp],

I was able to catch the case "491 Another INVITE transaction in progress" with version 16.10.0-rc2 (file fax_491.txt)
The good news - the asterisk wasn't crashed.
The bad news - T.38 re-Invite failed.

Should I open a new issue?

> During sending fax from Cisco SPA112 device through several Asterisk servers, latest updated server is crashed (Asterisk 16.9.0). But we can't reproduce crash, as sometimes faxes send fine, from other Cisco SPA112 devices faxes just stopped sending (receiving works fine). After downgrade to 16.8.0 everything works fine again.
