Detect main phone line busy

I would like to look for a software that would automatically dials our main business line number and send us an alert mail if the application detects a busy tone

This should be pretty easy to do. You need Voicent BroadcastByPhone for making outbound calls, and IVR Studio for design the call application.

When you use IVR Studio to design your IVR application, simply catch the “line.busy” exception, and then use the email action to send an alert email.

Select the newly designed IVR application from BroadcastByPhone, call your main number. That’s it.
