"Camping-out" on a phone line.

Greetings,

This is my first post to the community.  I did a search for "Camp" to see if anyone else had posted this request.  I found nothing related.  Perhaps there is another term with which I am not familiar.

We are a Zoom Phone user who migrated from an old PBX phone system.  We have been happily using Zoom Phone with few challenges we couldn't solve with documentation.  I would like to ask for a feature that allows a user to select an internal company contact to "camp-out" on their line.  This was the feature name on the PBX we used.  Here is the old scenario.  I pick up the phone to call Jane, but Jane is busy.  Rather than keep trying, I could press a feature key on the phone to tell the PBX to "camp-out on Jane's line and let me know when she hangs up."  When Jane hangs up, my phone would make a distinct sound to let me know Jane was free and it would offer to call Jane.

Since we can see if a contact is on another call right away, it would be nice to ask the app to "camp-out" on their line and let me know when they are done with their call/meeting.

I look forward to the comments/suggestions/ire this post may generate.

Have a nice day,

Marty
