First some background: The system is a conferencing system using a modified MeetMe. There are seven Asterisk boxes (we call them bridges) each with four T1 PRIs into a TE405P. No VoIP is involved. A conference is always local to a single bridge. The conference leader has a control screen and may dial into the bridge, or may instruct the bridge to dial him/her.

The problem: For the first three or four months of operation everything went very well, but from early February the customer started reporting problems with the volume of audio. Initially the reports seemed to be localized to a particular area of Texas, and to be small in number. Over time, they have increased in frequency and been reported from different areas.

I don't know where the older system is located, but I believe it is more local. This is obviously a worrying scenario. If anyone can suggest any ideas of ways to tackle the problem, and to determine whether it really is the Asterisk bridges or the phone systems, I would be very, very grateful, as it is turning into a nightmare!
