Webex calling Design

[Faisal Saoud]

If I have some sites, and every site has CME they are working fine together by dial-peer configuration. there is a new site, we will implement Webex calling there, let me explain the numbering plan at each CME site.

Site 1 numbering is: 1XXX

Site 2: 2XXX

Site 3: 3XXX

and we want to configure the new site 'Webex calling' numbering is 4XXX.

we will use LGW to route the new site to PSTN and other sites 'CMEs', my questions are

1. Can we configure the dial plan on Webex calling with 1XXX, 2XXX, and 3XXX to route the calls to Trunk and then to each CME without adding any prefix digits?
2. If we have a new branch 'Site 5' later and we will increase the Webex license, If we configure a new location on the Webex, does it require enabling this site to call the old branch 'Webex Calling site 4, 4XXX' without adding any prefix, or it's preferred to achieve that add the new site 5 to the same location of site 4.
3. on the CUCM there is something called CSS and Partition, what about the Webex calling, can we restrict any dial plan for some users?
4. Can we attach the trunk to LGW to more than one location to use it?

Hi there, 

1. Can we configure the dial plan on Webex calling with 1XXX, 2XXX, and 3XXX to route the calls to Trunk and then to each CME without adding any prefix digits?

SC: Yes, you can create a dial plan in Webex Calling for these patterns to route calls to your Local Gateway (LGW) (trunk).

1. If we have a new branch 'Site 5' later and we will increase the Webex license, If we configure a new location on the Webex, does it require enabling this site to call the old branch 'Webex Calling site 4, 4XXX' without adding any prefix, or it's preferred to achieve that add the new site 5 to the same location of site 4.

SC: If I understood your question correctly, you don’t necessarily need to create a site code (routing prefix) to call each other within Webex Calling. You can use any extension as long as the extension, user, phones, or any dial plan entity exists in the Webex Calling setup.

1. on the CUCM there is something called CSS and Partition, what about the Webex calling, can we restrict any dial plan for some users?

SC: You don’t have CSS and Partition in WxC, but you have similar functionality by using call handling features for outgoing call permissions.

1. Can we attach the trunk to LGW to more than one location to use it?

SC: Yes, you can also create a route group and assign multiple LGWs to the route group and assign the route group to respective locations for redundancy

@Shalid Kurunnan Chalil  Thank you so much for your response, another question what is the purpose of creating groups in CH, and can we integrate CH with Azure to sync specific users, not all users? 

[Shalid Kurunnan Chalil]

Yes, you can import users from a specific Azure group. The following may help you with the configuration or more details on it

Synchronize Azure Active Directory users into Control Hub (webex.com)

Sorry @Shalid Kurunnan Chalil for bothering you, but I have a new setup for the first time and the customer has some requests, and I haven't trained on a solution like this yet.

1. Webex user can have multiple devices with the same extension, can we enable each device to use specific dial plan based on the branch or all of them will use same dial plan.
2. Let's suppose that the Azure integration is working fine. If the administrator changes the extension of a user from Webex Calling, does Webex Calling update this extension on Azure as well?
3. As you know there are some branches with CMEs, how does the audio conference call work with phones registered on the cloud?
