Can I dial via a command parameter?

I want to be able to dial a # from my app.

eg 'ExpressTalk.exe dial=035984562' or something like that.

ET would already be logged on to my SIP.

Only the dialling would be automated.

Thanks

"C:\Program Files\NCH Swift Sound\Express Talk\talk.exe" -dial "18005551234"

Stunning! Thank you! Exactly what I was looking for.
