Viking 1600-IP Series Product Manual page 28

The Inbound Call Mode determines how the 1600-IP Series Phone handles incoming SIP calls. One option is to
generate a loud ring sound through the speaker. The 1600-IP Series Phone can also auto answer a SIP call to transmit
a page, control the relay or listen to transmit audio from the microphone. The last option is the silent monitor mode,
which allows callers to listen to the transmit audio from the microphone. The "secure" options for auto answer require
the callers to dial the access code in order to transmit a page, activate the relay or activate the optional RC-4A relays.
Factory Setting: Auto Answer
Disabled – Inbound SIP calls are not allowed.
Auto Answer – Inbound SIP calls are auto answered on the first ring. This can also be used for Silent Monitoring by
changing the Speaker Mode to 'OFF/Silent Monitor", See page 26. For more security use the Auto Answer Secure
Mode.
Auto Answer Secure – In the "Auto Answer - Secure" mode, the phone will automatically answer an incoming call on
the first ring. The unit will then output 2 beeps but will not go into two-way voice mode. After the 2 beeps are heard, you
will have 10 seconds to enter the pre-programmed 1 - 6 digit Access Code (see section 10 on page 24). When the
correct code in entered, 2 beeps will be heard and the unit will enable the Two-Way Mode (mic and speaker audio).
After the correct Access Code is entered, any of the "Remote Access Operation Commands" can be used (see
Operation, section B on page 31). Note: If the wrong Access Code is entered or more than 10 seconds have elapsed,
the phone will output 3 beeps and disconnect.
Ring: In the "Ring" mode the speaker phone will not automatically answer an incoming call but will output a loud ring
signal out of the speaker in a 2 seconds on, 4 seconds off ring pattern. There are four available ring cadences.
Ring with AGC: In the "Ring with AGC" mode the speaker phone will not automatically answer an incoming call but
will output a loud ring signal out of the speaker in a 2 seconds on, 4 seconds off ring pattern. The phone will automatically
increase or decrease the ring volume based on background ambient noise. The call can then be answered by
momentarily pressing the call button.
