3CX calling Cannot work without internet

[shahram jamal]

i was interested in 3CX and I tested on my raspberry pi , so its worked perfectly fine for video call ,voice calling,chat , voicemail , and so on , so i wanted to provide 3CX PBX for my customers as one of my services for a communication system for small and medium size of business but then i found one thing which is 3CX isn't working without internet , you cant make a call or anything without internet while i installed on my raspberry pi in my local network , its really a bad feature , i suggest to update it to work without internet except for annual Subscription

There are only two ways to make a phone call: (1) SIP trunks over the internet, or (2) use a gateway (analog, T1, etc.). Both options are possible with 3CX.
