Seperate group or Instance for each branch office in Call Manager ?

Posted on 2009-04-29
Last Modified: 2013-11-16
Can I configure the call manager for the branch offices to have separate groups and each group have their own extensions e.g I have CM in Head office and I want to connect the branch offices,but I want each branch office should have their extensions. e.g Branch A (200,201,202,..up to 2010) and Branch B extensions are the same (200,201,202..upto 2010) and same up to 50 sites ?
And each branch should not call the other branch office, if they want then they should call by press 9 and outside PSTN numbers.

Any help will be appreciated.

    Yes you can, you may create whatever dial plan you desire. The number of phones/sites you can configure will be based on your hardware platfrom and your network, but in general all that you are asking can be accomplished via Call Manager.

    Thanks Harbour for your great reply! I have Headoffice and CM 6 is installed in HO and operating, but we want 50 branch offices in two different countries, to connect to this central CM, but like I said earlier, the branch office must be in the  separate groups and each group have their own extensions  e.g Branch A (200,201,202,..up to 2010) and Branch B extensions are the same (200,201,202..upto 2010) and same up to 50 sites, but these branch (10 internal extensions) should only be dailed internally, if Branch A wants to talk to Branch B, call should go via PSTN ?
    - Can you provide any guid notes ?
    -Also for each branch office, I am going to install 2811 with E1 lines and DSL line. which should be more then enough for each site.
    - what dail plan to install for 10 extensions ?
