Is this the same thing that I might be getting on a TE405p? Most of the
time, everything works nicely, but sometimes, things go astray, and echo
comes into the conversation. Also seems to affect faxes with some lines
with errors during the fax. Finally, also sometimes get a red alarm on
the line, shortly followed by it going green again, of course, it drops
all calls in progress...

Adam
