Hi,
I have 5 E1 with libss7 1.0.2 and Asterisk 1.8.10.1.
The first one is with one telco and the others are with another telco.
I noticed that after some weeks running, four of my circuit stop working. I
can't make calls. But I can receive calls without problem.
When this happens, I can't see any IAM message on outgoing calls.
When I try to make calls, I receive:
-- Executing [1030851732342778@from-sip:1] Goto("SIP/Rede-00000e9a",

I receive this error: "cause 34 - Circuit/channel congestion", but Asterisk
didn't even send the IAM message.
My linkset is UP all the time:

To solve this issue, I need to make a "dahdi restart" command.
After this, all come back to normally.
But after several weeks (maybe five or six) I have the same problem again.
Anyone knows how can I make a more specific debug to diagnostic this?
