asterisk users - Jan 2005 - Multiple calls placed in outgoing spool interfer with each other

I am placing multiple calls in outgoing spool. (2 to be exact)
One calls my extension on a T100P.
The other calls my cell. This goes from Box A using IAX over to Box B
then connects SIP to my provider and calls my cell phone.

By now I have answered my extension - it begins speaking with automated
prompts. I answer my cell. Listen for a couple seconds then just hangup 
on the cell call.

This hangs up my extension also...

Anybody seen anything like this? I am using 1.0.4
