We currently receive intermittent HDLC errors:
Aug 27 17:58:26] NOTICE chan_dahdi.c: PRI got event: HDLC Abort (6) on Primary D-channel of span 1 [Aug 27 17:58:27] NOTICE chan_dahdi.c: PRI got event: HDLC Bad FCS (8) on Primary D-channel of span 1
When these errors occur, the line quality is very bad and some calls get dropped.
We believe that it could be the DAHDI drivers, as a reboot of the server resolves the issue. We did try to downgrade from Dahdi 2.2 to 2.1 but that failed.
We currently use:
There are 2 cards installed:
Both have a Wcte12xp echo cancel card installed.
Any help on how to resolve this problem would be appreciated.
