Voxalot FWD to Provider
 

Is there any way to call and have the number forward to the provider and then dial a number, this would be great on a mobile phone.

The feature is known as CallThru...it is not yet available on VoXalot officially...

You can however set it up with some tinkering... for a guide on how see Placing VoIP Calls from any Old Regular PSTN Phone

If you need any pointers or have questions about the setup (it is a bit involved ... but you only have to do it once) I'll be happy to help.
