fallback
The fallback function indicates how the PBX deals with calls which could not be transferred or rejected via call distribution.
Rejecting a call
The caller will hear the busy signal.
If an unassigned phone number in the PBX is required on an incoming external call, the caller will be transferred to the fallback function, the following SIP status codes available for the transfer to the exchange line:
SIP status on fallback | Transmitted message | Meaning |
|---|---|---|
Invalid number (404) | Not Found | The destination phone number has not been found or does not exist. |
Temporarily not available (480) | Temporarily Unavailable | The called subscriber is temporarily not available. |
busy | Busy Here | The called subscriber is busy |
Note: If a configured DDI (VoIP PTP connection) or an MSN (VoIP MPTP connection) is listet below, you can assign an individual SIP status code via SIP status on fallback .Fallback settings: The caller will be transferred according to the settings.
•Only Announcement before Answering: The caller hears the Announcement before Answering and then, the connection is interrupted.
•Fallback phone number and no Announcement before Answering: The call is immediately signaled at the internal number for the fallback.
•Fallback phone number and Announcement before Answering:
−immediately: The callIt is immediately signaled on the internal phone number for fallback and parallel to the announcement before answering.
−after Announcement before AnsweringThe call is signalled after the announcement before answering to the internal number for fallback and, thus, in parallel to the call phase.
Delayed fallback after
Requirements:
•Selected fallback number (see fallback)
All calls which have not been answered will be redirected after the configured time.
Note: The fallback time is the addition of the longest waiting time for the Call Forwarding on no reply and the seconds configured in after:. The longest waiting time will be determined by a comparison of the Delay time for CF on no reply in the PBX and the Delay time for CF on no reply.Linear call distribution (external = internal)
