COLP = Connected Line Identification Presentation?

[telepaul]

Hello

Is there someone hoe can tell my if the IPO supports the COLP or not on ISDN, and how to interact to it.
I have a customer hoe tells my when they pick up a call the person on the other site of the phone sees a different number on his display than originally dialled. Actually he sees the DDI number of the user. (COLP)
COLP = Connected Line Identification Presentation
Not the CLIP = Calling Line Identification Presentation

Thanks

Paul

COLP is not supported, following from Avaya docs:

The following supplementary services are supported:

Calling Line Identification Presentation (CLIP) Provides the telephone number of the incoming call to the IP Office.

Calling Line Identification Restriction (CLIR) Inhibits the telephone number of the IP Office being presented on an outbound call.

Connected Line Identification Restriction (COLR) Inhibits the COLP service.

Direct Dialing In (DDI) Where the exchange provides the last x digits of the dialed number on an incoming call. This allows IP Office to route the call to different users or services.

Sub-addressing Allows the transmission/reception of up to 20 digits, additional to any DDI/DID or CLIP information, for call routing and identification purposes.
