Turning off handling multiple calls at once

[cx45]

I have just moved to BT Cloud Voice, and have setup the 2 digital handsets that BT provided. Currently working okay, but i've noticed that when I am answering one call on one of the handsets, the other handset will still ring if someone else calls in and can be picked up and answered normally. I.e we can answer two incoming phone calls at once.

However, we want to see if we can turn this feature off as we only have 1 person answering the phones and we don't want customers left on ringing for a long time unanswered. 

Is there a easy way to simply turn it back so if the line is engaged, customers won't be able to ring through. We might think about a call queuing system in the future, but for the time being, ideally,  we just want to handle one call at once?

Hi cx45

For this there is multiple ways this can be setup. 
The main one is "Call Capacity Management", this can be found on the CV Service under Site > Features > Call Capacity Management. In this feature you can set a group in which you can set the max active calls, you can additionally break this down further into how many incoming and outgoing calls at once.
There are more complex ways to set this up if you requires more adjustment to how calls are routed. If the main number is on a Hunt Group you can use "Forward calls when not reachable" then selecting "Make the whole hunt group busy when at least one user is busy and the other users are not reachable"
Similarly, if the main number is directly assigned to a user and has "Simultaneous ring" assigned there is a setting "Don't ring my simultaneous numbers when I'm already on a call".
My recommendation would be to use Call Capacity Management for this task.
