Cisco SPA504G Paging & Intercom

One of the reasons I wanted to get a Cisco 504G was to test the FreePBX/Asterisk Paging & Intercom module. With every new phone release its always important to test the feature set before deploying to clients.

The paging and intercom work the same way as the SPA942 models. Just need to enable "Auto Answer Page" and remove any vertical service codes that might conflict with FreePBX paging/intercom codes.

There is a new multicast feature that enables paging directly from the phone - need to look into this more.

FreePBX Feature Codes & Cisco/Linksys SPA942 - SPA962

FreePBX provides many features but out of the box some of these will not work without some changes to the default Cisco/Lisksys SPA phones.

1. Your Dial plan should allow you to dial * plus at least 2 digits.
a) Can dial things like *97 or *98 for voicemail access
b) *100 to transfer calls to voicemail or dial directly into someone's voicemail without calling them

eg. (*xx.|xx.)


2. Your dial plan should also allow ** plus atl east 2 digits - this is used for Directed call pickup. Dialing **100 from a different extension will answer a ringing phone at extension 100.

eg. (*xx.|**xx.|xx.)

3. For Paging and Intercom to work you need to set "Auto Answer Page" to yes

4. Delete any vertical service codes that conflict with your assigned FreePBX feature codes
