All there, Just to let you know that this service is available at
www.easypabx.com ..(sorry administrator to spoil)
What exactly here is this:
You Dial your free DID number which points to a DISA.
The prerecorded message asks you for a pin.
You dial pin and get the dial tone.
You dial the desired number and the call goes through as per dial plan.
In fact if you combine this with callback then you have advantage of not paying for local call.
You ring the callback number and hang up.
The systems call you back via your VSP (which may be free), and connects you to DISA and then same as above.
Hope this help, and same Idea can be implemented in Voxalot.
(PS: EasyPABX will be closing their
FREE service by end of this year)
