I am seeking a solution that could hide the Caller ID number where the mobile operator DOES NOT allow caller ID hide.
The purpose is using VoIP termination thru GSM VoIP gateway, I do not want the SIM card phone numbers to be appeared on the called party, I am ok with bypassing the originator caller ID but NOT my SIM card numbers.
The only challenge is that the mobile operator does not allow Caller ID hide, so even if you tried to use #31# the call will not even go out! please feel free to contact me if you have any further assistance. Thank you
