ISDN PRI E1 on incoming call says: isdnAsn1Inv: error: unknown operation 12
I have a new setup consisting of a Call Manager v4.1.3 and a 2811 voice router with an NM-HDV2-2T1/E1 two port PRI ISDN card. The outgoning calls initiated from any IP phone to all destinations are all right, but incoming calls terminate with an unknown ISDN error.

debug isdn asn1 is ON.
Translation debug detail is on
Translation debug min is on
The debug output gives this with debug q931 and asn1, and nothing else, when an incoming call is received:
I came across this post from a Google search (and I realise it's many years old) when looking for some information on messages I was seeing when the ISDN was in a known diverted state.
If anyone else finds these messages, it's likely due to the Telco having a diversion on the entire service. Inbound calls are hitting the exchange port (which is causing the strange signalling) and then being diverted elsewhere.
I'm not able to access my old voice mail messages all of a sudden. The recording says something like 'the message is currently not available'. This has never happened before in all the years I have been using this system. I have t...
