Multicast Paging Settings
You can configure some general settings for multicast paging, for example, specify a codec, configure the volume and
audio device for listening to a paging call.
By default, all the listening groups are considered with a certain priority from 1 (lower priority) to 31 (higher priority). If
you neither want to receive some paging calls nor miss urgent paging calls when there is a voice call or paging call, or
when DND is activated, you can use the priority to define how your phone handles different incoming paging calls.
