PSTN Incoming call on real line disrupts VoIPcall over DSL
circuit<BR></FONT><BR></DIV>
<DIV></DIV>I'll lean this way too. I had a DSL line from Bell Canada in
Kingston, Ontario, and an incoming call on that line to the POTS phones would
cause VoIP traffic to become completely unintelligble. The VoIP call would have
to be re-established to fix things. A quick call to Bell had a technican out to
check the lines, and put a fix in place for me. <BR><BR>Alex Robar<BR><BR>

imagine that it was anything other than a bad<BR>> filter, but other than
replacing the filter (which didn't help), <BR>> nothing else stops working.
He can continue to use the Internet<BR>> connection on his PC just fine,

problems either, so the<BR>> Internet connection has not been lost.
<BR>><BR>> I have to admit to being completely clueless as to what to
