customer called complaining about low volume when talking to customers.. On site i tested co volts 46.9 to 47.5.(comcast). Checked the hand set's and the volume setting on the phones. Did a system reset. Could not duplicate the trouble. I hinted this usually means the processor is getting weak. I installed this over 10 years ago, first service call.
Thanks again, Gary S.

Try putting either a buttset or an SLT on each line to try to duplicate the problem. I'd also check the loop current to see if it is on the low side.

No. If it doesn't happen all the time consider that the problem is with the service provider, I wouldn't blame the ACS! Crappy VoIP crappy cell phones. I've never seen a Partner system do that but I've certainly seen VoIP and cell phones do it.

I have to agree with Hal on this one. I have a bunch of lines on my ACS at home, one pots, the rest voip. Pots line always has perfect volume, the voip lines are all different. No two have the same volume, some are very loud, some pretty soft. I had a line from comcast and when we ditched cable, that went too. It was the worst line of the bunch. It always had static on it, the volume was generally ok, but it would vary day by day. Towards the end we never used it because it sounded so terrible. I replaced it with an Ooma and it's been fine since. Fwiw, I have two Ooma's and they're both different in terms of volume. One is louder than the other, but both are acceptable. Just my two ¢.
