This feature can currently be used with ISDN PRI trunks or SIP trunks.
 It is recommended to use this feature with an ISDN PCB (PRI or BRI), however, analog trunks can be used as well.
 To provide a proper disconnect, Disconnect Supervision is required for the trunks used for this feature.
The Mobile extension internal extension number (Proxy Port) is linked to a speed dial bin to provide
integration.
 If all external trunks are busy when a call is made to the mobile extension, ringback tone is presented giving the
impression the phone is ringing.
A DID is directed to the Mobile Extension internal extension number (Proxy Port), and to provide internal
dial tone to the Mobile Extension, the incoming calling line identification of the Mobile Extension must
match the number in the Speed Dial bin. Once internal dial tone is presented, the operation is similar to
a single line telephone user lifting the handset.
In the absence of DIDs, the VRS can be used to transfer the Mobile Extension call to the Mobile
Extension extension number. This provides internal dial tone when the calling line identification is
presented and matches the number in the associated Speed Dial bin.
Alternatively, if calling line identification routing is enabled, the relevant Speed Dial bin could be
transferred to the Mobile Extension proxy port, which would then provide internal dial tone.
The number of Mobile Extensions per system is limited by the following CD-CP00-US rules:
64-Port Basic CD-CP00-US:

Number of Mobile Extension ports = 25% of physical ports (for example: If a system has eight
physical ports used, two Mobile Extensions are allowed).
256-Port CD-CP00-US:

Unlimited (limited only by available unequipped extension ports)
Max Port CD-CP00-US:

Unlimited (limited only by available unequipped extension ports)
When the limit is reached, the Mobile Extensions can be added in programming, but give the indication of an
invalid dial entry when called.
