Paging Single Extension

Can anyone tell me how to page a single extension (in otherwords call an extension and have the speaker phone automatically come on)?

Are you using a polycom phone? If so, I successfully implemented it following these instructions: … wer+config

Yes, I am using Polycom phones. However, my customer is wanting to activate the speaker on only certain calls to extensions, not all calls to that extension. Is there a way to preface the call with a code to activate the receiving extension’s speaker at will?

The way I set it up in my extensions.conf is to have the user dial an “8” before the extension when they want to page that extension, or just dial the extension normally to simply call that extension. The “SIPAddHeader” function below is the key to activate paging on a call. Here’s an excerpt from my extension.conf:

exten => _83[8-9]XX,1,SIPAddHeader(Alert-Info: Ring Answer)
exten => _83[8-9]XX,2,Dial(SIP/${EXTEN:1},20,r)

Then there’s of course the below for normal calls:

exten => _3[8-9]XX,n,Dial(SIP/${EXTEN},20,r)
