Call forward no answer to PBX over Qsig fails

CUCM v 8.0.3.20000-2

Voice GW 3925

Qsig link to PBX

Hi weird one here, got a qsig link to pbx can call back and forth no problem from the two units.

However we have set the call forward no answer to a pbx extension (can call it fine from all IP handsets) but when call forward no answer kicks in get the below error.

Call forward no answer timer is set to 20seconds.

Mar 20 04:21:03.845: ISDN Se0/1/1:15 Q931: TX -> SETUP pd = 8  callref = 0x0004

        Sending Complete

        Bearer Capability i = 0x8090A3

                Standard = CCITT

                Transfer Capability = Speech

                Transfer Mode = Circuit

                Transfer Rate = 64 kbit/s

        Channel ID i = 0xA98381

                Exclusive, Channel 1

        Facility i = 0x9FAA068001008201008B0100A132020101020115302A0201010A0103800103A109A30780053836333334A314801242616E6B7369612D423133622D3836333334

        Facility i = 0x9FAA06800100820100A119020100020100801142616E6B7369612D4238652D3836333433

        Calling Party Number i = 0x00A1, '86343'

                Plan:Unknown, Type:Unknown

        Called Party Number i = 0x80, '85500'

                Plan:Unknown, Type:Unknown

        Redirecting Number i = 0x000082, '86334'

                Plan:Unknown, Type:Unknown

Mar 20 04:21:03.957: ISDN Se0/1/1:15 Q931: RX <- RELEASE_COMP pd = 8  callref = 0x8004

        Cause i = 0x81E074 - Mandatory information element missing

Any help would be appreciated here

Think issue is with PBX but need to be sure

Liam,

Your facilities decode as

Facility Ie Data:
            Network Facility Extension: Len: 06
                sourceEntity: endPINX
                destinationEntity: endPINX

            Interpretation APDU: Len: 01
                discardAnyUnrecognizedInvokePdu

            RoseAPDU InvokePDU: Len: 32
                invokeId: 1

                divertingLegInformation2:
                    diversionCounter: 1

                    diversionReason: cfnr(3)
                    originalDiversionReason: cfnr(3)
                    divertingNr:
                        presentationRestrictedAddress:
                            unknownPartyNumber: 80, Len: 05
                                "86334"

                    redirectingName:
                        namePresentationAllowedSimple: 80, Len: 12
                            "Banksia-B13b-863"
                            "34"

It seems to me that you are sending a redircted call but not forwarding the redirecting number 86334 due to

presentationRestrictedAddress:
The far end want this information.

Can you check the settings on your gateway for OUTBOUND CALLS

Calling Party Selection

Calling Party Presentation

Also

Redirecting Number IE Delivery Outbound

Hey Alex,

Thanks for the response, been doing some digging and all settings were correct (calling party selection etc..)

Redirecting Number IE Delivery Outbound was enabed but I disabled it to test again.

The calls work with Redirecting Number IE Delivery Outbound disabled and call forward no answer.

Need to work with PBX vendor to sort out why their not seeing the number come across.
