Hello all,
I am a long time user of asterisk, first time poster to this board.
I have a mind boggling issue with libpri.
I used to have one of those cheap ISDN cards with the Cologne chipset, and I never had issues with dahdi.
I have since changed to a Digium B410P card, and it hangs at least once a day. For a while, I helped myself by a dahdi restart every 24h, now every 12h, but the problem seems to get worse.
I did a pri intense debug… The strange thing is - when this situation occurs, on incoming calls, the debug shows nothing.
On outgoing calls, debug shows this:
