Please bear with me - I'm learning all this stuff as I go and by reading the manuals - I've had no training.
And, I mis-stated something in the original post - my apologies.
To clarify: All crisis team phones have to ring (notification to implement the conference). Current set up is all phones are part of a coverage answer group (not a hunt group - my apologies) so that they simultaneously ring when triggered. I have an x-port extension that covers to the CAG as path 1, then to the vector. I also looked at a hunt group, but realized that it wouldn't ring all lines.
We already have a COR 14 set up for the loop phones. If I set up the x-ported "master number" as the only number in the Hunt group, would that make it where only the COR 14 phones could dial that extension and trigger the CAG ring/conference? What would I need to change, and where (besides adding the x-port ext as the hunt group member and setting COR 14 on the hunt group)? Would I need the x-port number if I set the coverage path in the hunt group, without any 'member' numbers?
