Telephone number - Can I replace SIM card telephone number with my own number?

Generally is the gateway able only request showing or hiding SIM card telephone number. The telephone number is stored on side of the operator and there is no telephone number (CLI) transmitted.

There is a way how to do it but it requires special infrastructure on operator´s side. 2N® VoiceBlue Next can send the number but only few operators in the world can work with this information.
