Asterisk 1.8.22 update

I am successfully running FeePBX 1.811.210.57-1 but my VoIP provider has made changes to their server that supposedly require an update to Asterisk 1.8.22.

Question: Does FreePBX 2.10 support Asterisk 1.8.22? And if so, how do I install the update?

I realize this is probably a novice question, but I have not been able to find an answer. Thanks.
