I don't have found anything related to my problem.

Let me explain more the app usage.

This appliaction is a 'caller', it's job was to call a
alphanumeric pager companie to place a call.

It scan a table at regular interval to check for a
new entry (timer), if it was an entry the program
disable the timer,place the call and re-enable the
timer.I use this method to avoid a call to the
function when a call(!) was in process.

It run continuously as service on an NT server.
It can do a lots of calls before stoping
with no apparent reason by itself.

I use MSCOMM32.OCX to make the calls.

I hope somebody can point me on the right direction,
it is very difficult to troubleshout this one!
