Extension Creation Overview
Yeastar Cloud PBX supports SIP forking, which enables an extension number to register on multiple SIP phones simultaneously.
SIP Forking
Yeastar Cloud PBX supports SIP forking, which enables an extension number to be registered by multiple SIP phones. When a call reaches the extension, all registered phones will ring simultaneously, and you can take the call from any device easily.
You can configure SIP Forking on the extension configuration page. The value of Concurrent Registrations limits how many SIP phones the extension can be registered on.
Note:
- The limit of concurrent registrations is 4.
- By default, if one SIP phone is busy, other SIP phones still can receive calls when calls reach the extension. To restrict other phones from receiving calls when the extension is busy, you can enable All Busy Mode for SIP Forking ( ).
