Hello, I've been playing around with two generic X100P analog cards to create a proof-of-concept system before we go ahead and hook up a PRI. I'm running into a reproducible problem with sound quality of bridged calls, and am hoping someone will be able to point me in the right direction. I have in my dial plan a _9. extension so outgoing calls can be made... the first thing is Wait(1) and then the Dial... A call comes in to the system and the menu plays with perfect quality. The call is then forwarded out the other analog line, and when answered the call quality is clear. The callee then presses # to transfer, and dials 9 then the number to transfer the call to. Immediately the call is disconnected from the callee, and the caller hears hold music. A couple seconds later when the caller is transferred, call quality deteriorates. There is a pulsating noise that causes the caller and new callee to barely be able to hear each other. This happens every time and only on the 2nd call. The first call is always clear. Any suggestions are most welcome. Thanks in advance, Trevor Peirce

It is done regularly on our PRI. -- Steven Critchfield <critch@basesys.com>
