How should we configure our Hyper Virtual Switch?
Since it's pure SIP we shouldn't have to worry about STUN over their router correct?
We usually purchase a our DID's trough a provider like Flowroute and send the SIP traffic to a separate public IP on our internet connection and route it to our 3cx server from there. We have a site where a decent internet connection wasn't available so the ISP is going to give us a SIP trunk that is delivered via a T1.
The provider will put in an adtran as their CPE and then is planning on giving us an internal 192 based IP to attach to our IP PBX. Our IP PBX is 3cx and will run as VM on HyperV 2012. We planed to do a external non shared NIC for the SIP connection and a External managed by the host NIC for the PBX. Will this work? Or is the fact they are giving us a non routable out of their CPE just causing my brain to lock up. It's seems foreign to get a 192 address for a service, I was expecting a routable public IP.
