I am considering a change from Trixbox/Asterisk to a 3CX system. One of the main features I don't want to lose is being able to change my outgoing caller id. Right now I can change the caller id by simply typing in a 2 digit code at the beginning of the call and then type the number I want displayed to the person I am calling + the number I want to call. I can also call into my system from my cell phone and make a call out from my system by doing the same thing but from my cell. Can a 3CX machine be set up to do the same? This is my fist post....I tried to find the answer on my own but had no luck. Thanks in advance.
