We use CallButler's PBX system. All of our extensions and everything are setup on our CB server hosted locally on the LAN. Is there a way that we can use the hold function with CB instead of the hold function in Express Talk? This worked fine with CounterPath's eyeBeam and Bria software and it would be great if we can get it to work with ET without having to replace the default Hold music in the app folder.
