This feature provides support for call forwarding (CF) services initiated by ISDN Basic BRI phones connected to the device. Upon receipt of an ISDN Facility message for call forward from the BRI phone, the device sends a SIP INVITE to the softswitch with a user-defined code in the SIP To header, representing the reason for the call forward.

The codes for the call forward can be defined using the following new parameters:

SuppServCodeCFU - Call Forward Unconditional

SuppServCodeCFUDeact - Call Forward Unconditional Deactivation

SuppServCodeCFB - Call Forward on Busy

SuppServCodeCFBDeact - Call Forward on Busy Deactivation

SuppServCodeCFNR - Call Forward on No Reply

SuppServCodeCFNRDeact - Call Forward on No Reply Deactivation

Note that these codes must be defined according to the softswitch (i.e., the softswitch must recognize them).

Below is an example of an INVITE message sent by the device indicating unconditional call forward (“*72”) to extension number 100. This code is defined using the SuppServCodeCFU parameter.
