I am trying to find documentation or something showing a Nortel IP 2007 phone is able to have a KEM using a BCM 50. Can anyone help me get something that shows this. I've looked at all the documents on the Nortel website, and either I'm overlooking it, or it just doesn't give me alot about KEM systems. I am mostly looking for a 24 button KEM for the 2007 phone.
