I have a 9000 and attached is the packet capture (using ethereal) of a single page from a spa941.
The spa9000 is at 192.168.2.1 and the spa941 is at 192.168.2.100. The way the paging system works is you dial *96, then either the individual phone you want to intercom with or you select the corporate directory and the entry named "pagegroup" which will page all phones in the same group as you. So in the first few packets you can see the phone doing the corporate directory lookup and then sending out the page. I'm not very good at analyzing packets so if you can learn anything from this capture please let me know. I'm looking at trying to figure out a way to add this feature to Asterisk so if anyone has any ideas please let me know. John On Fri, 2006-05-05 at 13:31 -0400, Simon P.
