please show the system.conf file, cat IRQ. i think something is wrong with
MTP, possbile reasons are:card problem or card setting.

Subject: [asterisk-ss7] Sporadic SS7 Link Down
Hi people!I have DAHDI Version: 2.4.0 with Asterisk 1.6.2.13 and libss7 1.0.2.
Sometimes the link was down and up (that is sporadic). The system doesn't have
many calls even.
Any suggestion?Is a problem of PSTN or is a problem with my digium?
Thanks!
Here is a debug result with the error....
