[Freeswitch-users] Paging - AASTRA phones

Hi All, How to build a dial plan for paging for groups of AASTRA phones. Here is my environment setup. FreeSWITCH on a Public IP address. All the AASTRA phones behind the Linksys WRT 54GL(Tomato firmware) . I see the following sample dialplan come with FreeSWITCH default.xml <extension name="rtp_multicast_page"> <condition field="destination_number" expression="^*pagegroup* $|^7243$"> <action application="answer"/> <action application="esf_page_group"/> </condition> </extension> What is the *pagegroup *variable referring to? Thanks Lloyd
