Figure 19: Whitelisted Devices
As soon as a SIP call is received by the GSC3510/GSC3505, it first checks if the Caller ID number is allowed on the Whitelist and then answers
automatically.
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).
Figure 20: Multicast paging Diagram
To receive multicast page, GSC3510/GSC3505 must be well configured to listen to the right address and port. The configuration is located under Phone
Settings 🡪 Multicast 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.
