ISDN PRI E1 on incoming call says: isdnAsn1Inv: error: unknown operation 12

[lfarago1]

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. Anyone has an idea of what's going on on this ISDN and what could be done?

running config excerpt from 2811:

I use the following debug:

The following ISDN debugs are enabled on all DSLs:

debug isdn error is ON.

debug isdn q931 is ON. (filter is OFF)

debug isdn q931 detail is ON.

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:

Thank you!!

Hi Laszlo,

This is the piece of information causing the error messages:

Component = Invoke component, Unsupported operation

The ISDN switch is attempting to use some ISDN supplementary services in the facility message that IOS does not support and can not parse.

hth,

Hello,

Thank you for your input.

I tried two other IOSs but was no help.

Finally, the PTT (T-Com) changed their ISDN PRI signalling somehow and it solved the problem, now works fine with incoming calls also.

It was not easy to have them do it...

Regards,

Laszlo

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.

Had the same errors below and yes, phones were diverted from provider.
