Curious if anyone has built or setup a solution that allowed you to bridge multiple FXS ports in one simultaneous call? We have a paging system with a unique campus setup where each of the units is a master for that building but does not connect to the other master devices in the other buildings on campus. In order to do a page across the entire campus using this solution, we need to open a channel on all of them at the same time or page each individually (not ideal). The inbound paging input for each system requires an FXS port. Thanks in advance for any feedback.
