Hey there,

I have a Fusion install with some speakers that auto answer a SIP Call for paging. This is excellent, however, I do not want just any phone to be able to call the extension and page over the speakers. I'm sure there is a way to use the dialplan to only allow calls to an extension (5700) from certain extensions (5100, 5200, etc), but I'm not what that entry should look like. Any help would be appreciated!

build a dial plan to check the caller id number

condition "caller_id_number" expression="^5100|5200|etc$"

Assuming that's extension to extension, I would copy the `local_extension` dialplan and add a check that:
"destination_number = ^5700$"
and as mentioned, do a condition that:
"${sip_from_user}=^(5100|5200|etc)$"
