GSC3516 APPLICATION SCENARIOS

GSC3516 SIP Two-Way/One-Way Intercom System

GSC3516 can be used as an Intercom System using built-in SIP accounts, once the SIP account registered the device can

receive paging/intercom calls and it will automatically answer calls coming from whitelisted numbers.

To register a SIP account on the GSC3516 the user needs to go under Account 󰒇Account X 󰒇General Settings, and enter

the account information as below, then save and apply the configuration.

Figure 9: SIP Account Configuration

Once the account registered correctly, the GSC3516 will show the account status under Status

Account Status.

Figure 10: SIP Account Status

By default, the GSC3516 Blocks non-whitelisted number under Calls →Blacklist/Whitelist/Greylist →Greylist, user needs to

either allow Non-White list calls or to set up a Whitelist that contains the number that will be allowed to call the GSC3516.

Figure 11: Greylist Calls

On the screenshot below, only number 1001 is allowed to call GSC3516:

󰒇

Figure 12: Whitelisted Devices

As soon as a SIP call is received by the GSC3516, first checks if the Caller ID number is allowed on the Whitelist and then

answers automatically.

Notes

GSC3516 is an intercom system and auto-answers all whitelisted numbers.

By default, GSC3516 plays a Warning tone when auto answering incoming calls, this warning tone can be disabled under

Account 󰒇Account X 󰒇Call Settings, “Play Warning Tone for Auto Answer Intercom”.

Multicast Paging Application

Multicast paging is an approach to let different SIP users to listen for paging calls from a common multicast IP address. In

multicast page call, an audio connection will be set up from sender to receiver, but the receiver will be only able to receive

audio, a one-way communication. The 2 entities, Sender/Receiver, must be located on same LAN (same broadcast domain).

To receive multicast page, GSC3516 must be well configured to listen to the right address and port. The configuration is

located under Phone Settings →Multicast/Group Paging. Up to 10 listening addresses are supported with priority levels

from 1 to 10.

Note: Multicast paging configuration requires a reboot to take effect.

Figure 13: Multicast Paging Listening Addresses

In above screenshot, Listening Address “237.11.10.11:6767” with label “Sales” has the highest priority.

Users can enable “Paging Priority Active” option (under Multicast Paging tab) to accept incoming paging calls during active

multicast paging. The paging call with higher priority than active one will be accepted.
