No not talking about a call director. There is a feature on the 3300 called "Call recognition" ( see help files ). You can setup PRI's with the feature and setup the system to recognize cell phone numbers from callers. The cell phone numbers usually are associated with a EDHU extension number and I believe when a user with a defined cell number calls the system recognizes this and starts threating them as an internal party. Did this a couple of years ago when it first came out and am pretty sure if I call the Nupoint DID it know who I was and asked for a passcode ( might have to define the EHDU ext number as a secondary extension in the mailbox ).
Call Recognition Service
Description
Call Recognition Service (CRS) checks the calling line ID of the incoming call to determine whether the caller is an external hot desk user (EHDU) and whether the trunk is "trusted" or "non-trusted." If the caller is an EHDU on a trusted trunk, he or she is automatically logged in. The digits dialed by the EHDU are then processed and the call routed to the intended station or other destination. If the digits terminate on the Hot Desking Access Number, then the user is provided dial tone and may continuing dialing.
A non-trusted EHDU must enter his or her PIN to log in. Without CRS, the EHDU would have to dial the Hot Desking Access number followed by their hot desk user directory number and User PIN to log in (unless they have "Permanent Login" enabled in their Class of Service).
CRS also provides integration with the Closed User Group (CUG) services (also known as Force-to-PBX or its abbreviation, FOPBX) offered by some mobile phone carriers. With CUG, all calls to, or from, a mobile subscriber are routed to a PBX over a dedicated trunk for processing. When used in conjunction with EHDU, the PBX can recognize calls made from mobile devices as originating from an EHDU by matching the PSTN number of the device to its EHDU directory number. To recognize that a call is being made to the mobile phone, the PBX matches the called party number (i.e., the PSTN number of the mobile phone) with the EHDU. Once recognized, the PBX substitutes the PSTN number with the EHDU directory number and routes the call to the EHDU. And since the PBX is always in the call path, it can maintain device state (busy, idle, call forwarding active, etc.) and offer mid-call features through DTMF detection.
