The problem is that your line provider may be switching this feature off when they suspect that you are
over using it. They may not even tell you and it may turn on and off until it drives you nuts!
You may want to check with your provider if they allow "Conference Calling". This is what it's called when you
initiate a call and then connect that number to a third party while exiting the call. It's different than three way calling
where you stay in the line. The phone companies frown upon the use of this feature because in actuality you are
calling more than one number at a time, therefore putting additional line traffic. If you do it while running
IVM's OGM outbound and making continuous calls, the line proiver, whether land or VoIP, will eventually turn off the feature.
I am trying to find a solution but so far have not found anything inexpensive.
