Just wondering if anyone can answer this question. I have set up 3CX and it is working great except that, i want to include a mobile into one of the ring groups. So far i have created an extension (100) to ring an external mobile number, this works fine i.e. you call ext 100 from any other extension it rings my mobile. I can also set the incoming line to answer then ring ext 100 (the mobile) this also works great. So when i add ext 100 to a ring group it rings all ext's on the list but fails to ring the mobile. I am using the free version and was wondering if the restrictions are the problem or does the software not do this?
