Im a newbie to Asterisk,. Im running voice termination business using chinese and European brand GSM gateways. Usually these gateway are pre installed with generic SIP-GSM software. The issue is that the Caller ID at receiving end is that of sim used in the gateway. I have been told that by integrating gsm gateway with Asterisk could hep alter the Caller ID. The mobile operator itself doesnt allow to change/alter the caller ID. So what I need to know is that is there any possibility to hide/change/alter the caller ID so that the receiving party could see a number I personally assign using Asterisk configuration?
