Paging means a one-way audio communication from one caller to a potentially large group of listeners. Typical applications include supermarkets, hospitals or trains. You may have several paging groups on one PBX that addresses different audiences. For example, you might have one paging account that calls a specific floor of the building, and you might have another group that pages the whole building.

Intercom is a potentially two-way communication between two participants. Intercom is controlled by the feature codes Intercom. In the previous version of the PBX, those two features were both in the paging group. In this version, they have been separated.

There are two ways to implement paging. The first way establishes regular calls to the paging recipients by using standard SIP calls (indicating that the call should be immediately connected by auto answer). This method works with most available SIP phones and there is also special equipment available that works as an overhead paging speaker. However, when the paging groups become bigger, it puts a lot of performance load on the PBX CPU.

Therefore the PBX offers a second paging mode, which just sends the RTP traffic to a predefined RTP IP address. Typically this is an IP multicast group. Phones and other overhead paging equipment will subscribe to that multicast group and go to paging mode as soon as they receive RTP traffic on this port. Using this method, you can build up very large paging groups with hundreds and thousands of speakers distributed in the organization.
