The Distinctive Ringing feature provides the ability for subscribers of a BG to hear different ringing indications for internal (within the same Business Group) and external calls (different Business Groups).
This feature permits the subscriber to distinguish internal and external calls based on the melody defined in the endpoint.
The administrator controls internal ringing for the entire business group.
The distinctive ringing feature is useable for subscribers of the following SIP endpoints:
optiPoint 410 S and optiPoint 420 S
optiClient 130 S
The actual alert indication strings (known as Bellcore-dr1 and Bellcore-dr2) must be defined in the telephone's alert indication section. If the strings are not defined in the telephone, the telephone rings with a default cadence for all calls, regardless of whether they are internal or external.
When the distinctive ringing feature is active for a business group, a different internal ringing pattern (Bellcore-dr1) is sent to the telephone for calls received from subscribers within the business group.
If this capability is not provisioned, the internal ringing pattern sent to the telephone is the same as the pattern defined for external calls (Bellcore-dr2).
