[asterisk-users] DAHDI 2.4.0 produces HDLC errors with echo canceler
Hi, 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[2743] chan_dahdi.c: PRI got event: HDLC Bad FCS (8) on Primary D-channel of span 1 [Nov 27 01:15:09] NOTICE[2743] 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: https://issues.asterisk.org/view.php?id=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 /etc/dadhi/system.conf. The PRI card I'm using is a Digium TE122. I'd prefer not having to run with the echo canceler off of course...

If so, it's strange indeed that the error goes away when you disable mg2. What is the complete output of your /etc/dahdi/system.conf? -- Shaun Ruffell Digium, Inc. | Linux Kernel Developer 445 Jan Davis Drive NW - Huntsville, AL 35806 - USA Check us out at: www.digium.com & www.asterisk.org
