DAHDI 2.4.0 produces HDLC errors with echo canceler

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:
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…

sip echo server

I’m trying to find a way to setup a SIP server that will mainly echo
back a request from one agent only,

my question is do i need to setup any of the other conf files besides
extensions.conf and sip.conf?

the book says “If you plan on a pure VoIP network, the only real
requirement is the asterisk package,” ,

but i’m doubtful about zaptel.

can anyone help me out?

How To Hangup All Channels

  1. sudo /etc/init.d/asterisk restart
  2. Write a script to do “asterisk -r -x ‘core show channels’”, parse the output and do “asterisk -r -x ‘channel request hangup ${CHANNEL_NAME}” for each channel.
  3. Write a script to do #2 using AMI.
