[VoIP] Cnet tandem stacking

[Lee Spenadel]

The switch caught fire and burned my house down.  The ensuing conflagration
ignited the pine trees surrounding my house and started a forest fire.  That
forest fire touched off a small munitions dump 2 miles away, which in turn
sent missiles hurling into several gas stations.  Having limited man-power,
the local Cape Cod fire departments have decided to let the fires burn out,
bringing the Cape back to its original Pilgrim landscape.

PS, the switch is fine.  Please check the number and try your call again -
message 349-4.

Hello,
This message is especially for Lee, but anybody who wants can chime in. I
was playing with your step switch, trying to get it to do DTMF to pulse
conversion on a stacked call as discussed earlier, and found that certain
digits, almost never the nine digit, would work. In one of these
experiments, the switch did something strange, then just locked up. Calls
into 8688 now get me a dead line on the switch, no dialtone. There's a
recording of what the switch did. Sorry for almost muted touchtones, I used
MixMonitor to record, and Asterisk is just getting IAX touchtones from my
IAXy. The file starts with my last successful call to the step, E.G. where I
get a dialtone, then dial out, then back in and get another dialtone. But
during the call, the step, or part of it, reset several times, it was like I
was going back to linefinder and getting a new dialtone, then it just died,
and I haven't gotten a dialtone since then. Interesting. Anyway, the
recording is at the following url.
