I have a call center using a 2 carrier G3 R8.3
One of their clients wants to have their vector play their own endless loop recording during queue. We assume we will interface the music source to an analog port via a voice coupler and assign that extension on the vector page. The G3 MOH is via a Lucent 909 universal coupler. Any tips on this setup and coupler options would be appreciated.

Thanks

Rich
