## Questions & Answers

**Q: Does the bm12 come with any power supply and or power cable?**
A: No it uses power from the phone... just plug it into the phone and wala

**Q: Will this work with Avaya 9508? and not sure on the answers about the power supply so does it or not need a power supply?**
A: Will work with Avaya 9508.  Does not require an external /additional power supply - it draws power from the 9508 via PoE.  It DOES require a special cable that is fairly difficult to track down & did not come with the package.  I had to get one from my Avaya rep.  It's the "mod cable" that connects the 9508 to the BM12.

**Q: Does this come with the connecting cable? (we already have the power supply)**
A: Yes. It comes with the connecting cable.

**Q: Is this compatible with the Avaya 9508 digital phone?**
A: yes, the Avaya 9508 digital phone will support up to 3 BM12 Modules
