When deploying a B2B (business-to-business) collaboration solution, there are several items that need to be configured. The two items that need to be configured are:
A. SIP trunk between Cisco Unified Communications Manager and Cisco Expressway-C C. SIP trunk between Cisco Unified Communications Manager and Cisco Expressway-E
Explanation:
SIP trunk between Cisco Unified Communications Manager and Cisco Expressway-C: A SIP trunk is a communication path used for transmitting and receiving SIP messages between Cisco Unified Communications Manager (CUCM) and Cisco Expressway-C. This SIP trunk is essential for providing secure communication between the two platforms. It also enables the Cisco Unified Communications Manager to handle calls for users located outside the enterprise network.
SIP trunk between Cisco Unified Communications Manager and Cisco Expressway-E: A SIP trunk is also required between Cisco Unified Communications Manager and Cisco Expressway-E. This trunk is necessary for call routing and for communicating with external entities. The SIP trunk is used for establishing a secure connection between the two platforms, and it is configured to handle calls from users outside the enterprise network.
B. Search rules in Cisco Expressway-E: Search rules are used to determine how incoming calls are routed within the Cisco Expressway-E. They are used to match the dialed number to the appropriate destination, whether that is a specific user or a service. Search rules are critical in ensuring that calls are routed correctly and efficiently within the B2B collaboration solution.
D. Traversal client on a Cisco Expressway-E: The traversal client on a Cisco Expressway-E is responsible for handling incoming and outgoing calls to and from the external network. It is essential for providing secure communication between the internal network and external entities. The traversal client is responsible for handling NAT traversal, firewall traversal, and encryption.
E. DNS zone on a Cisco Expressway-C: A DNS zone is a domain name system (DNS) database that contains information about the domain names and IP addresses within an organization. In the case of a B2B collaboration solution, a DNS zone is used to resolve external domain names to internal IP addresses. A DNS zone on Cisco Expressway-C is optional but can be used to enhance the security and efficiency of the solution.
In summary, when deploying a B2B collaboration solution, two items that must be configured are SIP trunks between Cisco Unified Communications Manager and Cisco Expressway-C and between Cisco Unified Communications Manager and Cisco Expressway-E. Additional configuration items include search rules in Cisco Expressway-E, traversal clients on Cisco Expressway-E, and DNS zones on Cisco Expressway-C.
