setting up a shared front desk phone

[Timt]

We are moving from a SIP phone system with a local PBX to Zoom VOIP. We have a front desk operator and several back up employees for while they are out. 

I set up a call queue to ring sequentially for the front desk operator. with those three users. It was pointed out to me recently that if the front desk person is on vacation and sets her extension to out of office or Holiday, the phone at the front will not ring. The other two extensions will ring. At their desks but if one of them is sitting up front, that phone will not ring. 

Is this correct? Is there a solution other than making the front desk phone a community area and setting it to HotDesk? If I do that will the two people who may need to be up there have to log off their desk phones when they go to the front desk to fill in? 

thanks for any advice or help you can offer.
