meters away and configured in redundancy mode. 7941/7970s are in the same
location as secondary CME. They have difficulty registering to the primary CME
but ok to secondary CME. When checking CM list from phone's Setting
button, CM 1 is listed with a DNS name matching nowhere and CM2 with right IP
address of the secondary. </span></font></p>
