Do you know if there are any e.164 country codes (CC) that provide a gateway from PSTN reachable numbers to URI (SIP) for their whole range
The only example I know is iNum (+883 5100 country code) Each iNum number can be converted into an URI in the form of : sip:
Are they similar systems for other country codes? This would allow for free calls to a whole country range, even if the endusers did not register their number within enum.
Thanks & Best Regards. Julien
