In this figure, the CS 1000 has a HLOC of 354 and an LOC dialing plan entry of 344. The LOC dialing plan 344 is not dialable, however, calls to the DN: 6712 extend the call to the number 6-344-5000. By PCA extending the call to 6-344-5000, a SIP Invite is sent to the OCS Proxy server.

The OCS Proxy server runs MCM, which handles the Invite and reads the Original Called Number as 354-6712. The call is sent to the Mediation server and To and RequestURI are mapped to the Line URI. In this diagram the user is mccarthy@ocs2007a.corp.nortel.com

The purpose of configuring is to ensure that the Office Communicator has the same phone number for both incoming and outgoing calls.

Configuring the Personal Call Assistant

Personal Call Assistant (PCA) is used to "twin" incoming calls so users can answer the calls on either their desktop phone or Office Communicator 2007.

For incoming calls to be extended to the "twinned" Office Communicator client, a PCA Terminal Number (TN) must be defined for that DN. A new PCAM Class of Service prompt has been introduced so a distinction is made between PCA associated with the OCS 2007 client and PCA associated with other types of clients. Class is configured using BCC. For more information on BCC, see Basic Client Configuration. PCA associated with the OCS 2007 client, the class is set to PCAM. Other types of clients use the default class PCAG. During call processing, the class is checked to determine whether an incoming call should be extended to the PCA target DN or not. For more information about configuring PCA, see Features and Services (NN43001-106).

The PCA TN is configured to send the call to another number. In the case of "twinning" to Office Communicator, the call is sent to a number that is not dialable but routes the invite to the Office Communications Server. For more information, see Configuring the Dialing Plan to route to MCM.

ATTENTION

IMPORTANT!

If SIP CTI control is also enabled for that telephone, the PCA TN cannot be

MARP 0.
