I'm getting ready to migrate my phone system from an existing 3CXv8 (running on XP with a real computer) to a new v9 setup with Win2k8R2 in a Hyper-V VM. I'm using http://www.3cx.com/blog/docs/hyper-v-instance/ as a guide and have a few questions. The article says what is this for? The article says what us this for? I don't really have an issue with doing these things, I'm just curious what they are for. I will not be using the Sykpe feature. I plan on using Abyss. I have about 20 extensions and use a VOIP provider. Any other thoughts or suggestions would be appreciated.
