Description (partial)

Symptom:
CCM service will core.

Conditions:
1.)          Third party SIP Phones sharing a line should REGISTER with CUCM.
2.)          CUCM should use 'Digest Authorization' headers to find the deviceName and later it should update it. [i.e. Phone sending SIP Register message shouldn?t be present in the system, auto registration should happen using the actual deviceName it gets via authorization header of the SIP message.]
