Mediant 600 & Mediant 1000
Event: ua-profile
Content-Type: "application/simservs+xml"
Message body is the XML body containing the “dial-tone-pattern” set to "standard-
condition-tone" (<ss:dial-tone-pattern>standard-condition-tone</ss:dial-tone-pattern>),
which is the regular dial tone indication.
Therefore, the special dial tone is valid until another SIP NOTIFY is received that instructs
otherwise (as described above).
Note: if the MWI service is active, the MWI dial tone overrides this special Call
Forward dial tone
18.5.2.5.3 BRI Call Forwarding
The device supports call forwarding (CF) services initiated by ISDN Basic BRI phones
connected to it. 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 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: These codes must be defined 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. This code is defined using the
SuppServCodeCFU parameter.
