I have an Inter tel system and recently got a music on hold system. I have connected it to my phone system but can barely hear the recording when on hold or as background music. Is there a place to boost the volume within the phone system?

No, use the volume control on the music source.

Make sure the 1/8" plug into the PBX is mono, not stereo.

It is mono and I did turn up the volume on the music on hold box. If i plug my phone in to the music on hold box, I can hear the music fine. If I take a Telco tester set and hook it up to the output cord, all I hear is the recording real low. I have asked them to send me another box but wanted to make sure there was not something I was missing in the Inter-tel set-up for Music on Hold. Thanks

Is there an impedance switch? If so, make sure it's set for 8 ohms and not 600.

You should hear the music clearly on the butt set.

Been told to find a Radio Shack Grey RCA to 1/8 mono cable. That it is just a fraction longer on the tip then their black one. Anyone heard of this?

If you're using a mono to mono cable, you may have phase cancellation, otherwise known as comb filtering. You need an adapter to go from stereo to mono. Such as this.

Thanks everyone for you help! This is what I did. I went to Radio Shack and picked up several RCA to Mono 1/8 adapters and put it one on the RCA to RCA cable that came with the music on hold and it has volume now!!!
