I have an IP Office 500 with 8.44 and 9508 phones. All phones have Huntgroup button (200). Is there a way that if someone answer a call and place it on hold it will lights up the Huntgroup button on all the phones so someone else can press the Huntgroup button to answer the call that is on hold. I know the Park key will work, i am just trying to make it simple for the users. Thanks in advance.
