I recently tried to set up a Dial-Up server for my vintage computers and after reading some more about it, I decided to buy myself a cheap PBX from China. I managed to find two versions of the PBX in question. One that supports GSM, and the other one, which doesn't. My quesion is: If I plug in the Dial-Up server to one of the ports on the PBX, would I be able to access it from outside, via GSM?
Thanks in advance.
