After upgrading to DAHDI 2.4.0 from Zaptel, I noticed a lot of HDLC
errors on my console:
[Nov 27 01:15:09] NOTICE chan_dahdi.c: PRI got event: HDLC Bad
FCS (8) on Primary D-channel of span 1
[Nov 27 01:15:09] NOTICE chan_dahdi.c: PRI got event: HDLC Abort
(6) on Primary D-channel of span 1
These errors prevented calls from being made and received on my PRI spans.
This seems similar to bug 15498:
Which says this was fixed in 2.2…so maybe it got back into 2.4?
I can get rid of the errors by disabling the mg2 echo canceler in
The PRI card I’m using is a Digium TE122.
I’d prefer not having to run with the echo canceler off of course…
