I am not very familiar with a lot of the old Nortels but the ones I have taken over (MICS and CICS) all have a page port but do supply power. There has always be an external power supply. Either way you just need a power supply and should be good.

One pair for power and one for audio. So really if I can just feed it 24v, the snom should still work if I put in a line level adapter? Can't I just turn the output way down on the speaker output to achieve the same thing?

If the speakers where existing, there is most likely a 24 power supply there now. If not you can order one form valcom. They measure their power in VPUs, each speaker has a VPU rating. Make sure you get one large enough to handle all the speakers. [https://img.newoldstamp.com/f/000/012/u555.png?5852f657df370]<http://trueipsolutions.com/> Brian Hales Chief Tech.

I have a Snom PA1 but that won't work as we initially thought because speakers need 4 wires on a 24v power system. So 2 wires are for 24v power, and the other 2 are for audio. The snom only has a positive and negative output that feeds passive speakers, not active speakers like these. What is the best way to utilize these 3 speakers or should we just replace the speakers? We're trying to keep budget to a minimum for them so we would prefer to utilize the same speakers but what's the best way to power them and feed them audio using the existing 2-pair RJ11 cable they use?
