Cisco SPA IP Phone Field Reference Phone Tab A Multiple Paging Group Parameters You can configure a phone as part of a paging group by using a Group Paging Script. Users can then direct pages to specific groups of phones. A phone can be part of no more than two paging groups, and user can page a maximum of five paging groups. Syntax: pggrp=ip-address:port;[name=xxx;]num=xxx; [listen={yes|no}]]; Where: IP address: Multicast IP address of the phone that listens for and receives pages. port: Port on which to page; you must use different ports for each paging group. name (optional): The name of the paging group. In this name, do not use the pggrp string because it is reserved. Using it causes the script not to work, as in these examples: pggrp=224.168.168.168:3141;name=ITGPgGrp; num=800;listen=yes; pggrp=224.168.168.168:3141;name=PgGrp;num=800;listen=yes; num: The number users dial to access the paging group; must be unique to the group. listen: If the phone should listen on the page group. Only the first two groups with listen set to yes will listen to group pages. If the field is not defined, the default value is no, so you must set this field to listen to the group pages.
