A couple of our phone users who have both a desk phone and a SIP client on their iPhone have commented that when they are on a call on their desk phone, their SIP client on their iPhone can ring with another call, instead of the caller receiving a busy tone.
This is annoying for both parties - the caller, because they don't realise that the person they called isn't ignoring them, they simply cannot take 2 calls at once. And for the DEE user, because whilst they're trying to concentrate on the call they're on, their mobile phone is ringing in the background.
Is there a way of changing this behaviour so that the system gives a busy tone when they're on a call on either phone?
Thanks in advance,
