Create a FreeDigits.com account and forward your calls to the VoipDiscount URI
User@sip.voipdiscount.com. Then you can use the SipBroker.com PSTN access numbers with the SIP prefix *665 that corresponds to FreeDigits followed by your FreeDigits number.
This way your call will be forwarded from FreeDigits to VoipDiscount and effectively you will have a free DID number linked to the VoipDiscount account which will also be accessible from the SipBroker PSTN numbers.
It works with SipDiscount.com, NoNoh.net and presumably with all other Betamax sites (
betamax price comparison).
One point to note is that from within the VoipDiscount login page a call can be forwarded to any PSTN/mobile number on a permanent basis. This may be usefull to people who are on the move.
