A customer of mine is having issues with making conference calls. When making a conference call, once the third party is connected, no one can hear above a whisper on the speaker phone. If the call is just a normal 2 party call the conversation is heard clearly. They have tried different phones and different co lines to make the conference call with the same results. Any ideas of what to look at would be great. The the co volume boost has already been turned up to +3db. any higher than that and you get line squeal. The system is a STS ver 2.0 I believe and they are using the standard 3015 24btn phones. They are about 2hrs away from us so looking to get some ideas before I make the trip. Thanks for your input.

Judging by the slow response I am guessing I am screwed on this one?

Please be a little more patient. Judging by your time stamp, you have only waited 54 minutes! Many of us run businesses and aren't just sitting here waiting to answer forum questions.

What happens if you press Mute? Does the volume come up? Perhaps there is ambient room noise that is effecting the vox switching. One would think this would also apply to non-conference calls but it would still be helpful to know.

Another item to test would be to enable Group listening. Does this affect the speaker volume?

You might also consider setting the CO lines for "long loop" in programming. This may help.

Thanks for the tips. I will give these a try and let you know how it works out.
