Change outgoing caller ID number?

[fongo2u]

One great feature that Voxox offers is the ability to select whatever number you want when you make an outgoing call. You get a local, forwardable number and input that into your outgoing dialer. Then when people call you back there's only one number involved. It makes things very neat and tidy. I couldn't see any ability to do this but is there another way? I realize I can change the name for SIP to SIP calling but 99% of my calls are to POTS or cell phones. Many do not answer if its not a local number thinking that its some phone solicitor. And that name for the SIP to SIP wouldn't show up on calls to POTS phones, right? If so I could put in my other number at least in the place of the name. It would look weird of course but it would be better than a non-local number.

This would be a GREAT feature to implement.
Another question: Why don't they allow you to forward your number to your Skype account?
