I'm trying to get SNMP to tell me if a SIP-trunk on CUBE goes down, and get back up again.
Look aside from the physical interface i want to know if the next call leg is available.
CUCM -> SIP -> CUBE -> SIP -> PSTN
The CUBE does have ISDN as an alternative route if the SIP-trunk to the provider fails. The ISDN has been widely used without me being able to se why. This goes for both incoming and outgoing calls. Now i want to see if SIP is telling me something i don't see.
I'm not looking for the physical interface but what SIP (options and keep alives) are telling me.
The physical interface never goes down but still every now and then the calls are routed in and out AAR (the alternative route on ISDN).
I want to know, without debugging the CUBE to death, what happens.
Isn't there an SNMP trap to tell me that?
There must be a way to gather the same information that SIP uses to determene that the next call leg is dead and decides to use the alternative route.

the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
