We recommend that you change the Cisco Webex SIP subdomain after hours or during a maintenance window, because the domain doesn't change immediately.

Before you begin

For Hybrid Call Service Connect deployments, when you're migrating an existing SIP address with the ciscospark.com address, use the Migrate Cisco Spark Hybrid Call Service Organization to the Cisco Webex Domain guide.

If you don't see an option to edit your subdomain you must first deactivate Hybrid Call Service Connect for your organization: go to Services, choose Edit settings on the Hybrid Call card, scroll to Call Service Connect, and then click Deactivate. This step temporarily converts you to a cloud calling organization.

From the customer view in https://admin.webex.com, go to Settings, and scroll to SIP Address for Cisco Webex Calling.

Click Edit Subdomain and choose from the following:

  • Add a new Webex subdomain—Enter a new subdomain value, and then click Check Availability. You're presented with a webex.com address.

  • Migrate an existing SIP address with the ciscospark.com address—Click Check Availability and you're presented with both your current ciscospark.com address and the webex.com address. This option preserves backward compatibility when migrating to the new Cisco Webex branded addresses.

  • Change an existing Webex subdomain—Enter a new subdomain value and click Check Availability. You're only presented with a webex.com address. Any previous ciscospark.com address is not retained.

Click Save.

  • If you have migrated your existing SIP address, click Ok and this triggers the migration process that adds Webex SIP addresses. You can click on View update history (tasks) to see the status of the SIP address changes. If there are any issues, you can review the errors and then click Rerun Task.


     

    After the migration completes, Webex-registered devices in a Place (Room, Desk, and Board) may show the ciscospark.comaddress as Primary. This can take up to 24 hours to fix, but calling is not affected during this time.

  • A Cisco Webex SIP address is automatically created for each user. If the address isn't created for your users or places, contact support using Support Assistant.

What to do next

If you have migrated your existing SIP address, you can verify that the SIP address changes were completed:

Expected Result

Users

Go to Users, click any user, click Calling, and then you'll see the primary and backup SIP address entries.

Go to Places, click any place to open the overview pane, click Calling, and then you'll see the primary and backup SIP address entries.

In a Hybrid Calling deployment, after the subdomain and Cisco Webex SIP addresses are updated, reactivate Hybrid Call Service Connect for your organization: go to Services, choose Edit settings on the Hybrid Call card, scroll to Call Service Connect, and then click Activate.
