Distinctive Ringing

Distinctive ringing uses a special ringing pattern to alert the called user of incoming calls from
preselected telephone numbers. This is a CLASS feature and is offered to both business and residential
users. There is no difference between provisioning the feature for SIP and provisioning it for MGCP.
You can edit the list of selected numbers though the Screening List Editing (SLE) feature, which requires
the configuring of an IVR with the BTS 10200. Distinctive ringing can be assigned to a station and to
the group, and it can be applied to users based on the call type/calling number. When assigned to a group,
distinctive ringing is applied to users in the group based on the call type. When assigned to the line,
distinctive ringing is applied to the user based on the calling number. The BTS 10200 sends an Alert-Info
header in the outgoing INVITE message, instructing the SIP phone to play a specific ring tone.
Distinctive ringing depends on the SIP phone’s capability to support processing of the information
received in an Alert-Info header.
