Managed Service Providers and Enterprises are increasingly providing centralised services for telephony, including the resale of geographic numbers (DIDs) for multiple countries.
The voice wholesale market, particularly in Europe, has re-introduced tariff complexity based upon commercial rates linked importantly to both A (origination) as well as B (destination) number classification.
For example, different rates now apply for a French number to call a Swiss mobile than compared to a UK number. It can be that 500% to 1000% price variances may exist. As a result, surcharge qualifying calls may be being blocked by your carrier based upon the A (origination) number classification.
