Hi We are looking at rolling out a music broadcast and PA system for a shopping mall. The music would play all the time and be interrupted by announcements on the PA system. We have Snom phones that we use with 3CX and I know that there is a Snom PA1 that connects to external speakers and amps and designed to be a PA system that integrates with a SIP system. I know that 3CX doesn't have a line-in 'music on hold' feature anymore. Perhaps I could have a separate non-3CX SIP system that provides music to the Snom PA1 and then have 3CX interrupt the music for announcements. Has anyone successfully integrated 3CX do this with a Snom PA1 or something similar? Thanks.
