When configuring a customer through a CCW (Cisco Commerce Workspace) order, the partner should provide the Provisioning Contact email address. This email address is used for setting up and provisioning services for the customer, ensuring that all required information and communication is directed to the appropriate person responsible for managing the deployment.
Cisco Reference
Cisco's CCW guidelines detail the importance of providing accurate contact information, including the provisioning contact, for customer configuration.

Webex customer trials are created and managed through the Cisco Commerce Workspace (CCW). CCW allows partners and Cisco account managers to configure and provision trial services for customers, enabling them to test and evaluate Webex services before making a purchase decision.

For more details on creating and managing Webex trials, refer to the Cisco Commerce Workspace documentation.

To enable TDM (Time Division Multiplexing) connectivity in a Webex Calling environment, the IOS Gateway type is required. An IOS Gateway is a Cisco router that can handle traditional TDM connections and convert them into IP for integration with modern VoIP systems. It supports various interfaces, such as E1/T1, to connect legacy TDM-based PBXs or other telephony equipment to the IP network.

Cisco's documentation on Local Gateway (LGW) types and TDM connectivity requirements highlights the use of an IOS Gateway for such purposes.

Webex Teams applications support TLS version 1.2 only for secure communications. TLS (Transport Layer Security) version 1.2 is currently the most secure and widely accepted version for encrypting data transmitted over the internet. Cisco's adoption of TLS 1.2 ensures that Webex Teams provides strong encryption standards and meets modern security requirements, protecting data integrity and confidentiality during communication sessions.
