Hi Guys, Unusual one here. Looking to setup SIP trunk in Qatar, have 3CX installed SIP trunk installed by Ooredoo however was handed a sheet of paper with some IP addresses on it which make no sense. The main issue here is that Doha uses 1 IP similar to China and you need an IP Key to allow NAT'd traffic. So I got that and can NAT away but still having issues that their support haven't got back to me on which I was hoping the 3CX community may have some experience with. This is what the little bit of paper stated; SIP-T VOICE WAN IP: 192.168.161.x /30 ESBC MGMT WAN: 192.168.215.x /30 CPE MGMT IP: 172.19.62.x /27 CPE MGMT IP: 172.19.62.x - Different IP CPE MGMT GW IP: 10 This is not my first setup however this seems rather strange. They have presented an Ethernet cable which is plugged up to a secondary NIC on server with the VM having both a local network and this SIP cable connected. I know it will be a static route but hoped someone could shed some light on this or hoping someone else has had dealings out there that could point me in the right direction.
