Chris & Brian, Thanks. I finally manged the paging working for AASTRA phones. This is modified intercom dialplan with group_call <extension name="extension-paging"> <condition field="destination_number" expression="^8000$"> <action application="set" data="dialed_extension=$1"/> <action application="export" data="sip_auto_answer=true"/> <action application="bridge" data="${group_call(pagegroup@ ${domain_name})}"/> </condition> </extension> I will try the multicast with a Cisco Router support GRE Lloyd On Tue, Mar 23, 2010 at 3:46 PM, Brian West <brian@freeswitch.org> wrote:

Hi Lloyd, in the Aastra phone you may set up to receive the multicast paging by "Group Paging RTP Settings " under "preferences", just put multicast IP address and port, then you can do multicast paging, however if I am understanding correctly it only working in LAN environment, I don't think you can forward multicast traffic through internet unless you sign up the multicast services.
