Setting Up Multiple Extensions with DP750


I am trying to setup three DP730 with a DP750 base using CallCentric.

I have setup three extensions with CallCentric.

I have been able to register one extension (the default one) that works for incoming and outbound calls. However I want to setup the other two phones. However when I go to add extension 101 and 102 I am unable to register them. I have checked the user name (for example: 1777#######102) and password.


need more details like the screenshots of your settings, or if you can get a network traffic trace by the Packet Capture tool will be help to locate the issue
