CHAPTER28 Configuring Supplementary Services
Mediant 1000 Gateway & E-SBC | User's Manual
To enable the feature, configure the UseFacilityInRequest ini file parameter to 1.
➢ To configure the digit codes for call forwarding services by BRI phones:
1. Open the Supplementary Services Settings page (Setup menu > Signaling & Media tab >
Gateway folder > DTMF & Supplementary > Supplementary Services Settings).
2. Under the BRI To SIP Supplementary Codes group, configure the reason codes for call
forward:
● 'Call Forward Unconditional code' (SuppServCodeCFU)
● 'Call Forward Unconditional Deactivation' (SuppServCodeCFUDeact)
● 'Call Forward on Busy Code' (SuppServCodeCFB)
● 'Call Forward on Busy Deactivation' (SuppServCodeCFBDeact)
● 'Call Forward on No Reply Code' (SuppServCodeCFNR)
● 'Call Forward on No Reply Deactivation' (SuppServCodeCFNRDeact)
3. Click Apply.
The call forward codes must be configured according to the settings of the softswitch
(i.e., the softswitch must recognize them).
Below is an example of an INVITE message sent by the device indicating an unconditional call
forward (“*72”) to extension number 100. The code is configured by the SuppServCodeCFU
parameter.
