VG200 PRI NI2 Problem

Have a VG200 running 12.2.11T with MGCP talking to Call Manager 3.2.2c.

Problem that I am seeing is that looking at debug isdn q931 I see that we are "sending" a 10digit calling number, but the Telco NOC is saying that they are only seeing the last 7 digits. On Call Manager, for the gateway we have all the defaults for the gateway line definition dial plan and type of "Call Manager". in the debig it is showing the type and number are Unknown. Is this what is causing the problem? What options would change this?

Thanks. The following is a snippet from the debug:

5w2d: ISDN Se1/0:23 Q931: TX -> SETUP pd = 8 callref = 0x01DA

Bearer Capability i = 0x8090A2

Standard = CCITT

Transer Capability = Speech

Transfer Mode = Circuit

Transfer Rate = 64 kbit/s

Channel ID i = 0xA98397

Exclusive, Channel 23

Progress Ind i = 0x8083 - Origination address is non-ISDN

Display i = 'Ralph Scorza'

Calling Party Number i = 0x0080, '5188624766'

Plan:Unknown, Type:Unknown

Called Party Number i = 0xA1, '13153868561'

Plan:ISDN, Type:National

5w2d: ISDN Se1/0:23 Q931: RX <- CALL_PROC pd = 8 callref = 0x81DA

Channel ID i = 0xA98397

Exclusive, Channel 23

5w2d: ISDN Se1/0:23 Q931: RX <- ALERTING pd = 8 callref = 0x81DA

Progress Ind i = 0x8088 - In-band info or appropriate now available

5w2d: ISDN Se1/0:23 Q931: RX <- CONNECT pd = 8 callref = 0x81DA

5w2d: ISDN Se1/0:23 Q931: TX -> CONNECT_ACK pd = 8 callref = 0x01DA

Re: VG200 PRI NI2 Problem

NO, the UNknown type and PLAN are appearig for the CALLING number. That would have no effect on the telco digit screening tables. THey would look at the CALLED number, and that one is set for Plan: ISDN type: NAtional

I would strip the "1" off the front of the 315 number though, as it may be throwing off their digit screening tables and they may be sending it to a local switch that only screens the last 7 digits of the call.

The call above has CONNECTED though, so the call was routed , but perhaps to the wrong destination ?

Re: VG200 PRI NI2 Problem

The Calling number is what I am concerned with. What I think I am doing is sending a 10 digit number as the Calling number but the Telco is telling me that they are only seeing 7 digits for Calling. Is there anything that is in that display that would indicate that I am sending 10 digits? And does the Unknown Plan and Type for the Calling number be causing any problems.

Thanks.
