At times we have staff that call department queues. We can't pick a queue from the telephone presence selections, so we need to create an extension that forwards to that queue as a work around. It would be nice to be able to just select a queue as a button option. It would also be nice to be able to use "Call Monitoring" and "Pickup" buttons in the same way. For now we need to program those on the individual phones, and then have a custom template applied to the phone using both presense and manually programmed buttons on the phones.
From Mitel/Shoretel on premise phones to Ring Central, the button features were really lacking in comparison, it would be a good way to boost the features of the product line in general.
