The Redirect 3PCC to H.323 station from SIP desktop station feature redirects the third-party Call Control (3PCC) actions from a SIP desktop station to one of the following :

• Remote H.323 soft phone

• Virtual private network H.323 telephone

You can enable the feature by activating the Prefer H.323 over SIP for Dual-Reg station 3PCC Make Call field or a FAC.

The two FACs that can be used to activate and deactivate the Redirect 3PCC to H.323 station from SIP desktop station feature are:

• 3PCC H323 Override SIP Station Activation

• 3PCC H323 Override SIP Station Deactivation

You can start the 3PCC action by using an ASAI 3PCC make call request. If the ASAI link stops working or the station is no longer under domain control, the feature is deactivated.

The computer telephony integration (CTI) application can use any domain-controlled extension to originate the FAC call.
