David Brillert commented on ASTERISK-24822:
-------------------------------------------

This is happening several times a week on multiple sites.  Anywhere that has T.38 gateway mode enabled and decent call volumes.
I really need a fix.  We have to disable T.38 to bring stability with no deadlocks but at the sacrifice of unstable faxing.  This is really starting to hurt financially.
