ISDN error Code Inbound

getting the following error when calling a dn.

Cause i = 0x82E1 - Message type not implemented

Dialing phone to phone (4 digit) works fine. Any thoughts? Route Plan Report shows no overlapping

Re: ISDN error Code Inbound

Are you pulling this from your gateway or trace logs from your CUCM? Can you be a bit more specific about the DN you are calling? Is this an internal or external call?

Pulling it from debug q931 off the gw. Actual number is external coming in through PRI. It originates as an inbound 800#, terminating on the 9200 DID

Does dialing the DID number work? Can you post the full debug?

Re: ISDN error Code Inbound

Dialing the terminating DID number does not work. Here is the debug

Re: ISDN error Code Inbound

Message not compatible with call state:

The remote equipment received an unexpected message that does not correspond to the current state of the connection. This is usually due to a D-channel error.

Re: ISDN error Code Inbound

Are you sure you have the correct ISDN switch type configured? Since this sounds like a D channel error, perhaps the signaling is not compatible? Does the error occur just on this DID?

New Member

Re: ISDN error Code Inbound

yes, all other did's and 800 inbounds work fine

Re: ISDN error Code Inbound

do all the other numbers come in on thru the SAME PRI??

or do they use a different PRI??

Re: ISDN error Code Inbound

Did you port these numbers from another carrier? Perhaps they didn't port this DID correctly? Is it a part of another DID block or is a single number?

New Member

Re: ISDN error Code Inbound

I know this is an old Post, but I am having the same issue with the exact same setup mess

age you are getting, it is only happening on one DID, Telco is saying

Gateway is sending a Set_ACK instead of Call Proceding thus

they are sending back a "Message type not Implemented". Did you ever r

esolve this?

Cisco Employee

Re: ISDN error Code Inbound

Looks like you have an overlapping dialplan on that number somewhere.

The Setup_Ack is sent if overlap receiving is enabled.  For MGCP that is controlled with 'Overlap Receiving Flag for PRI' service parameter in CM, and is enabled by default.  For H323/SIP, issue 'no isdn overlap-receiving' which is disabled by default.  That will prevent the setup_ack from going out.

The error from the provider is a result of either your provider not supporting overlap sending, or perhaps you are configured for the wrong ISDN switch type.
