[asterisk-r2] suddenly system has become unstable

[Anton Krall]

No, no incoming or outgoing.. Zttool shows all channels as 1001 rx and 1001
tx but no calls come in or out.

Do you have incoming calls at all?

As I said before, seize time out is the same as if a SIP interface sends an
INVITE and never gets a reply, the only difference here is that the INVITE
is a CAS signal sent through the E1, we send the CAS signal but never get a
reply, either because is not getting into the card or because the card or
driver is not reporting the response (or not sending the CAS signal at all).

I suggest you to contact Sangoma technical support, they should be able to
help with the CAS signaling troublesooting. Particularly, what I think we
would need is a system that can no longer make calls, DONT restart wanpipe,
and then we can see if the cas signaling is not being sent or received.
