Hi all,
in need some help, hope i can explain my problem correctly.
Our company uses a third party contact center solution and we have different call center extensions for each departement.
The SIP Trunk connection works fine between Callmanager and contactcenter server with XCAPI, all is full in service.
Now i need to route all departments contact center extensions into the CC-SIP Trunk.
For example i have the extension "7777" and "6666", in the Technotes from CC to connect with UCM is defined like these Route Pattern.

First i don´t understan completly what this pattern exactly doing?
I´m not sure if there is an easyer way to route all my 12 Contact Center Extensions into the CC Trunk.
If you have any ideas, I would be very happy to hear them.
Thanks
