I am using FreePBX 2.7.0 and a Valcom IP Page which is used to send voice announce to remote paging systems via IP Page Ports. I am looking for a dial plan which will automatically connect the Valcom IP Page to an conference when another extension dials a ring group. I am trying to connect everyone in the ring group and the IP Page device into a conference automatically. Member in the ring will automatically dial the conference when they answer the ring group call.
Please restate your call flow. Please be more detailed.
Also, be aware FreePBX 2.7 is EOL and unsupported. You need to upgrade to 2.9 or 2.10 the current supported versions.
What version of Asterisk are you running?
