First part of configuring the UCM6100 series should be about planning for expansion. Here are some
questions to think about when setting up extension ranges:
• How many users are in the office?
• Will there be departments within the office?
• Is this office interconnecting with another office?
Once there’s a clear picture of how many users will be at each location, how departments are going to be
segmented and what’s the expected growth of the company, a user can then configure the extension
range. Navigate to PBX
 Internal Options  General.
Figure 4: Create User Extension – Extension Range
In the figure above, the user extension range is set with a starting extension of 100 and ending at 195.
This allows up to 196 extensions to assign to users. We have also created a conference extension range
from 196 to 199, which gives 4 conference bridges. Users can configure any extension range as they
desire. Here we’ve configured it to use three digit extensions with a leading 1.
Click “Save” at the bottom. Then remember to click on “Apply Changes” at the top so that our extension
range will be ready for the next steps.
