Extension Mobility and Calling Search Space

If a Extension Mobility user leaves Atlanta and goes to Houston and logs in, won't his Calling Search Space still have calls going out Atlanta? How does the search space change so local calls use whatever city he is in? Or is this not a feature?


Re: Extension Mobility and Calling Search Space

Calling Search Spaces can be set at the device and/or line levels. The line level CSS takes precedence. If you leave the line level CSS for the device profile set to None, the user will have the device level CSS of the phone where they log in.

Hope this helps. If so, please rate the post.

Re: Extension Mobility and Calling Search Space

You will need to create Local Partitions (Such as Atlanta_Par and Houston_Par, plus a "User" Partition such as User_Par)

Then create your Route Patterns, for simplicity make a 9.@ in the Atlanta_Par and point it to the Atlanta Gateway and then make a 9.@ in the Houston_Par and point it to the Houston gateway.

Then Create 3 Calling search Spaces. One for the Houston phones (Houston_CSS ) and put the Houston_Par and User_Par in that CSS. then Create one for the Atlanta phones (Atlanta_CSS) and put the Atlanta_Par and the User_Par in that CSS. Now I like to create Partitions and CSS for Dialing Restrictions for the Line but for simplicity just make a User_CSS and only put the User_Par in it.

Now once you have done that, any phone that is phyically in Atlanta, in the Device page of that phone select the Atlanta_CSS and for the phones in Houston select the Houston_CSS.

In the Device Profile of your extension mobility users under the line put them in the Users_Par Partition and the Users_CSS Calling Search Space.

What happens is when they make a call the two Calling search spaces (one on the Device and one on the Line) will combine, So if they log into the phone in Atlanta When they call out it will search through the Partitions in the User_CSS and also the Atlanta_CSS since we have the 9.@ in the Atlanta_Par Partition it will match and go out the Atlanta gateway.

Hope that helps

Re: Extension Mobility and Calling Search Space

Brandon and Ken nailed this.

But, I always put the 9.@ route pattern in the DN CSS so the users don't have to learn a new dialplan for every site they visit. I use the device css for local resources like E911, operator, paging, etc...
