And again, this is just this last month... It is not always like this.
So it begs the question, what has changed at the other provider? Line
conditions, modem code, busy signals? I don't know. However in the last 6
months we have been growing faster than we can add lines. Typically we
average abou 3 to 5 signups a day.

Their switch doesn't even support caller ID. Its just antiquated, so I
don't know weather messing with it does anything to help.

Like the USR-TC being twice as much way back when? That is the main
reason we went with the PM3, that and the PM2eR's worked flawlessly.

I couldn't agree with you more on this. The biggest problem we have seen
with the PM3 is that when initially setting up a CT-1 the telco gets no
response from the PM3. It basically looks dead. You can plug a T-Berd
into a PM3 and send all 0's or 1's all day long and get nothing back.
Its pretty much a crap shoot getting lines provisioned for a PM3...
