One modification to my previous dialplan:
[hotdesk_outbound]
includes (via cascade) internal-calls

exten => .X,1,NoOp()
…snip do stuff to determine who’s calling, set their extension number to WHO…
same => n,Set(GROUP(activecalls)=${WHO})
same => n,Set(DEVICE_STATE(Custom:${WHO})=INUSE)
…snip make the call…

Needs to be:
[hotdesk_outbound]
includes (via cascade) internal-calls

exten => .X,1,NoOp()
…snip do stuff to determine who’s calling, set their extension number to WHO…
same => n,Set(GROUP(activecallers)=${WHO})
same => n,Set(DEVICE_STATE(Custom:${WHO})=INUSE)
…snip make the call…

And similarly, all checks or use of GROUP_COUNT(${WHO}@activecalls) should be changed to GROUP_COUNT(${WHO}@activecallers). I missed the fact that setting GROUP(activecalls)=${E} later on in my dialplan was overwriting the GROUP(activecalls)=${WHO} for intra-office calls, and thus breaking my ability to see that the person placing the intra-office call was “on another line” if a second call rang their phone or what have you.
