First thing you do on a new CM is save translations and reset system 4. Can't remember if R7 forces you to have a license to start with. Media Server won't work without a license for itself to run the software instance. Then CM needs a license for the media server to use whatever number of channels you purchase. Avaya licenses the channels via CM and charges about the same as 1/320 of a G450 so the DSPs cost the same, you just save the space and power footprint.

You won't regret it!
As far as your no dial tone problem, if your phone's regsiter and can call each other, CM thinks the medpros are up. Follow the packets.
If you go in dom0 of system platform and ifconfig you'll notice that there's a bunch of NICs. Like vSwitches, it'll have networks/vlans avpublic and avprivate. Then dom0 will have vif1.0 vif2.0, vif 2.1, etc. Those virtual interfaces are assigned to each VM Say vif2.0 and vif 2.1 would be the public and private interfaces for the second virtual machine.
System Platform uses avprivate - 172.20.10.1 for dom0, .2 for cdom, etc, to comfigure the virtual machines in the background.
Playing with tcmdump should help you follow the flow.
But, most importantly, what are you trying to learn and why? What's your background?
If you work at a company that happens to run old CM 5.2 and you want to move into the telecom department - then good work, you're on the right track. If you're trying to get a better job as an installer or designer and want some proficiency with the system, I'd strongly recommend you include SIP at every step of the way - so, System/Session Manager and Branch Session Manager/SBC and the UC applications. 10 years ago, SIP clients and phone firmware was clunky, a pain, didn't work as good and not many people were getting hands on with SIP phones because there was no practical reason. Today, a lot of people can still get by with H323, but the SIP stuff is a lot more mature in Avaya's stack and would be considered required learning each step of the way.
