Call extension when user is available

Sorry, I don’t know the term for this otherwise I would try harder to look it up. I have a BLF set up on my Yealink T-32G that shows when the other user is on the line. Can I dial a Feature Code so the system will ring his line when he hangs up (user is available)? I have done this as a user on Cisco systems before (busy ringback?). Just wondering if it can be done on FreePBX.

System - Asterisk 11.16.0 / FreePBX 2.11. Yealink T32G phones.

It’s called Camp-On.
