Finnaly after ordering michael's book we are able to implement CUPS and MOC 2007. (including call control)
The problem is, to get the phone system integration active, I had to change my SIP userID (m.bastinck) to my cisco callmanager user id (numbers only). I prefer to keep my old SIP userID but it's impossible to use this sign-in name for extension mobility.
Is there a way i can keep my cisco user id (numbers only) and SIP userID (m.bastinck)
