Calling number display over T2 SIP trunk

[DS_Eire]

Hi,

I have a T2 SIP trunk from my OXE going to a 3rd party PBX. For incoming calls to the OXE, the OXE iptouch phone will display the calling party display name but it does not display the calling partys number. Is it possible to display the calling partys name and number across a T2 trunk from a 3rd party PBX.

Is there a paramater to allow this or is this even possible? Calls between my local iptouch phones display name and number fine.

Some settings:
Network Routing Table has - Protocol Type + ABC_F

Trunk Type is:
Trunk Group Type + T2
T2 Specification + SIP
Q931 Signal variant + ISDN all countries

Thanks
