Guys who set up the VoIP-GSM gateway OpenVox VS-GW1202-4G?

Question

Asterisk

Good day!
Today I bought this gateway, OpenVox VS-GW1202-4G, and I have to set it up so that I can use it in the office as a mini-PBX for the first time, before I buy a server. Faced with the fact that there is little information on the Internet about its configuration. You need to set up call forwarding, queues, voice menu, and so on.
Please tell me where to find good manuals, if any, and share your experience!

Answer 1

So this is asterisk, there is enough information on it.
