9.9 SIP Hotspot
SIP hotspot is a simple but practical function. With simple configurations, the SIP hotspot
function can implement group ringing. SIP accounts can be expanded.
Set a phone as a SIP hotspot and other phones (B and C) as SIP hotspot clients. When
somebody calls phone A, phones A, B, and C will all ring. When any phone answers the
call, other phones will stop ringing. The call can be answered by only one phone. When
B or C initiates a call, the SIP number registered by phone A is the calling number.
To set a SIP hotspot, register at least one SIP account.
