asterisk users - Sep 2004 - Incomming ring on POTS line kills ongoing voip call?

Hi All,

A curious thing started to happen recently. My Asterisk server uses
IAX2 to several ITSPs for outgoing calls, but I still have two POTS
lines for incomming calls. One of those lines has the DSL circuit from
my ISP. When that analog line rings it forces * to drop any IP based
calls that happened to be ongoing. It happens regular like clockwork.

I have DSL line filters protecting the analog phones and FXO devices.
My POTS lines are from SBC and I use a Siemens Speedstream 5360 DSL
modem connected to a m0n0wall router running on a Soekris Engineering
embedded PC.

Any idea what I can do to overcome this problem?

Thanks,
Michael

Try starting an FTP file transfer of a very large file and then dial that
voice number and see if the ftp transfer drops or pauses.  It could be that
the ringing is causing the DSL signal to drop off.

If that is your problem, then replace the filters and then complain to SBC
that ringing is causing the DSL signal to get lost.
