I have a few item that I think will enhance S series and are important:
1. A LOG IN/OUT button for queues and groups. A BLF indication of a phone's status in a group is a big missing feature on SPBX. My customers have asked for it. If there is a way to do it I would like to know. If not please implement!
2. A feature code similar to *70 the resets forwarding to previous settings not to defaults.
3. In call forwarding options of Extension include forwarding to group. I know this can be done with custom number, but I think it should be an option. Also if it is an option, have the ability to leave message not in forwarded group, but of original forwarded extension.
