I am recent purchaser of the 3cx system and have come up against a couple of challenges with the paging system structure.
1. A page should not affect an active call on an extension. If I am talking with somone, the system puts that call on hold and plays the page. That is not acceptable and we have already had complaints from our customers that it is rude, not to mention very inconvienient.
2. Pages should not forward to an outside line when the extension is set to forward calls. Internal extension to extension and external calls should be sent, but not paging.
3. Having some type of support for multicasting support for devices like the Valcom VIP-201 paging server. We have a large manufacturing floor and require the use of a speaker based system. I cannot use the multicast approach to paging because the VIP-201 will not support it. Not sure how that might be done, but it sure would be nice.
