Well, not really. I found out the hard way that an Ephone-DN in CME that isn’t configured from the start as a dual-line can’t be changed to a dual-line. So, no consult transfer or putting a call on hold and calling someone else. No big deal, just “no” the existing one and add it all back in as a dual-line. Just don’t do what I did. When you do a “no” on an ephone-dn it not only wipes out the DN, it also removes all references to that DN. Including any button assignments on ephones! And hunt groups! Yeah!
The reason this happened is because I decided to use the GUI for some phone configuration on a new system. I thought it worked great until I realized that it had added the DN’s as single line only. Maybe it’s an option in the GUI but I missed it and haven’t gone back to check it out yet. If it’s not in the GUI that’s a travesty!
I guess the lesson is, learn CME from the CLI and you can’t go wrong.
