[asterisk-ss7] ss7 link down

Sun Apr 18 22:50:46 CDT 2010

Asterisk 1.6.2.0

libss7 version: 1.0.2

DAHDI Version: 2.2.0.2 Echo Canceller: MG2

Also I have pri channels 

libpri version: SVN-branch-1.4-r1439

you need to use chan_dahdi.conf when using libss7, maybe in chan_ss7 it’s not  necessary.

Somebody can help me, is this log critical ?

I think chan_dahdi is not necesary when using chan_ss7, are you using chan_ss7 or libss7 or what?
My apologies if the answer becomes obvious, however my little knowledge narrows down to chan_ss7 only.

Below are portions of my chan_daddi and ss7.conf
