SIP Settings Page
The settings shown are typical for other types of SIP endpoints, such as a SIP Phone. An
exception is the
Send Radio COR/AUX Status
setting. If set to
Enable
, the status of the COR and
AUX Input pins on the ARA-1 rear panel will be sent across the IP link. This is useful if your
radio has a hardware squelch line (COR) and you are linking to other ARA-1 units. Sending COR
Status will tell the other units when the radio is unsquelched, and the other radios can assert their
PTT control output lines if they are part of the connection. This is a more sure and timely method
than the use of VOX or VMR as the network audio gating function at the other ARA-1 units. See
also Section 3.3.5.
