Shoretel phones are MGCP rather than SIP.
Asterisk does have a configuration file for MGCP.
It is advised to learn the core concepts prior to trying that though.
It is also best to start with SIP.
Also if you don't have the budget for a course and the timescale does not matter.
You could get to grips with the book "Asterisk, The definitive guide" by Russell Bryant, Leif Madsen, Jim Van Meggelen.
That would introduce you to much of the terminology.
