anchorOverview

Webex Calling provides advanced telephony services for its users. The Webex Calling APIs provide an interface for third-party provisioning, which can be used to provision Webex Calling users. Call Controls provides information about active and past calls and can be used to perform call actions. Voice Messaging provides summary information regarding new and old voice messages, and can be used to perform voice message actions.

Usage Notes

When creating, updating, or retrieving Webex Calling users:

• The callingData query parameter must be set to "true" to retrieve Webex Calling details for the user when using the People API

When creating users:

• To create a Webex Calling user, include the phoneNumber or extension, a Webex Calling license, and (optionally) the user's locationId
• If a locationId is not specified when creating a user with a phoneNumber or extension, or both, then the organization's default location will be used
• If the phone number is invalid, neither the phone number nor the extension will be created and associated with the person

When updating users:

• You can only add a locationId when applying a new Calling license to an existing user
• If you do not specify a locationId when adding a new Calling license to an existing user, the default will be used
• You cannot update the locationId for an existing Webex Calling user

Working with Phone Numbers:

• Webex Calling APIs only support the primary phone number and not alternate phone numbers
• For US Phone Numbers use the format without country code ([area code][number]), e.g. 5715551212. The following are not supported: e.g. +15715551212, 15715551212, 571-555-1212.
• Non-US numbers must use E.164 format ([country code][area code][number]), e.g. +335715551212
