I’m interested of building an Asterisk PBX for my office, but have a question regarding how to integrate it with GSM mobile phones.
Basically, what I need to be able to do is to transfer all calls coming to my office phone (extension) to my GSM mobile phone, when I’m outside the office. I would like to also have the telephone number of the caller (Caller ID) to show up on my mobile phone when it rings, instead of it showing my office number.
So what hardware and software requirements do I need to make this possible?
Thanks for your help.
