SIP CME - authentication register
For SIP CME configuration, you will find local phones can register to CME without the need of "authentication register" command. The CME will authenticates the MAC address compare with the ARP request.
For remote phones that are NOT in the same subnet, SIP digest authentication is required. You need username and password stored in the phone config file, and compare it against the voice register pool.
Without "authentication register", when you do a "debug ccsip message", you will see 401 Unauthorized for the remote phones.
"authentication register" is a global settings and will affect all phones.
