Hey all liking the 3CX softphone for windows alot! Is there anyway to set a dial out prefix on this phone? I need it to dial "90" If I put "90" in front of the number I just get a busy signal. Just tried out xlite and I was able to specify a dial out prefex which allows me to make calls. As of now I can only call extensions in the office with 3CX. There must be a simple way to dial 90 before the numbers.
