Button Separators In Cisco Unified Communications Manager Express (CME) and UC500

Cisco IOS button commands

I've seen a bit of confusion on the site regarding Button Separators used for assigning an Ephone-dn (or extension) to an ephone.

an example of the syntax to assign a extention with ephone-dn tag 17 with a normal ring, to button one on an ephone with a tag of one would be:

ephone 1
mac-address 1111.2222.abcd
button 1:17

There are different separators available to you from the command line:

Overlay dn button commands:

An overlay set allows you to map many ephone-dns to one physical button on the phone.

an example of the syntax to assign a extention with ephone-dn tag 17, and ephone-dn18 , to button two on an ephone with a tag of 3 would be:

ephone 2
mac-address 1111.2222.abcd
button 3o17,18
