A client wants an app that'll run through their Leads table, and allow their telemarkets to dial the phone number in the current record.

I've been looking at the MSCOMM32.OCX code example in Files here, and that might do it. However, I was wondering

1) Does the person doing the calling need to take the phone off-hook, then click to dial the number?
2) Are there any gotchas I neeed to be aware of?
3) Is there any way to do this in native VFP code?
4) Are there any add-ons that'll do this?

Any help appreciated!
