RE: SIP-T20P: Register Failedand and no Call
IS the widows firewall on or off?
The firewall would be blocking 5060 Sip registration.
If possible, also put the laptop on a fixed ip...
3cx can provision the phones automatically if they can see each other.

And I think you mean you added 2 extensions - 500 and 501. The phones are Yealink T20's (Endpoints).
