Calling Party 'Unknown Number' over T1 PRI

sergiodovinte

Level 1

I have a T1 PRI dms-100 over MGCP.

There is a Translation Pattern that routes the T1 numeration to a Hunt Pilot -2100-. This is a assigned to a Hunt List and a Line Group of extensions where the operators answer the calls.

My problem is that I'm not receiving the Calling Party number on the phones screens. I always receive 'Unknown number'.

I tried with different combinations on the T1 Gateway configuration (tried changing Calling party IE number type, Calling Numbering Plan, Display IE Delivery... etc). I have also checked into the Translation Patter that Use Calling Party's External Phone Number Mask is enabled, don't know if i have to enabled it on the Hunt Pilot too.

A debug q931:

Jan 11 18:12:33.466: ISDN Se0/1/0:23 Q931: TX -> RELEASE pd = 8  callref = 0x0065

Jan 11 18:12:33.490: ISDN Se0/1/0:23 Q931: RX <- RELEASE_COMP pd = 8  callref = 0x8065

Jan 11 18:12:38.474: ISDN Se0/1/0:23 Q931: RX <- SETUP pd = 8  callref = 0x0A0C

        Bearer Capability i = 0x8090A2

                Standard = CCITT

                Transfer Capability = Speech

                Transfer Mode = Circuit

                Transfer Rate = 64 kbit/s

        Channel ID i = 0xA98384

                Exclusive, Channel 4

        Progress Ind i = 0x8481 - Call not end-to-end ISDN, may have in-band info

        Called Party Number i = 0x80, '8XXXXXXXXX6'   <----------------- It Shows my T1 numeration OK

                Plan:Unknown, Type:Unknown

Jan 11 18:12:38.910: ISDN Se0/1/0:23 Q931: TX -> CALL_PROC pd = 8  callref = 0x8A0C

        Channel ID i = 0xA98384

                Exclusive, Channel 4

Jan 11 18:12:38.914: ISDN Se0/1/0:23 Q931: TX -> DISCONNECT pd = 8  callref = 0x8A0C

        Cause i = 0x80A2 - No circuit/channel available

Jan 11 18:12:38.942: ISDN Se0/1/0:23 Q931: RX <- RELEASE pd = 8  callref = 0x0A0C

Jan 11 18:12:39.126: ISDN Se0/1/0:23 Q931: TX -> NOTIFY pd = 8  callref = 0x860C

        Connected Address i = 0x80, '2100'  <----------------- It's the Hunt Pilot where the T1 is routed to in the Translation Pattern

        Notification Ind i = 0xF1

        Display i = 'XXXXXXXXXXXXX'

Jan 11 18:12:39.158: ISDN Se0/1/0:23 Q931: RX <- STATUS pd = 8  callref = 0x060C

        Cause i = 0x82E16E - Message type not implemented

        Call State i = 0x0A

Jan 11 18:12:39.362: ISDN Se0/1/0:23 Q931: TX -> RELEASE_COMP pd = 8  callref = 0x8A0C

Jan 11 18:12:46.186: ISDN Se0/1/0:23 Q931: TX -> DISCONNECT pd = 8  callref = 0x860C

        Cause i = 0x8090 - Normal call clearing

The Operator Company says that this service is active by default on T1 PRI.
Any ideas?

Telco is not sending calling number.

If they claim otherwise, have them come on premises with their test equipment, and challenge them to show it to your eyes.
