Cisco Expressway at the Collaboration Edge Design Session

Cisco Expressway at the Collaboration Edge Design Session

Cisco Expressway at the Collaboration Edge Design Session BRKUCC-2801 Kevin Roarty Technical Marketing Engineer Cisco Collaboration Abstract Cisco Expressway is an important part of the Collaboration Edge Architecture offering a mobile and remote access alternative to VPN. The solution allows Jabber clients to securely traverse the enterprise firewall and access collaboration services deployed on the enterprise network. Remote Jabber clients will have access to voice/video, instant messaging and presence, visual voicemail, and directory look-up services. This session will include a solution overview including how Jabber clients connect over the edge and register to Unified CM, the evolution of Expressway firewall traversal, options for IM & Presence services, and also how remote TelePresence endpoints can now register to Unified CM through Expressway. Participants will receive design guidance including deployment options, limitations, best practices, required software versions, and security considerations.

Internet Unified CM Expressway C Firewall Expressway E Firewall Signaling Media 1. Expressway E is the traversal server installed in DMZ. Expressway C is the traversal client installed inside the enterprise network. 2. Expressway C initiates traversal connections outbound through the firewall to specific ports on Expressway E with secure login credentials. 3.

Once the connection has been established, Expressway C sends keep-alive packets to Expressway E to maintain the connection 4. When Expressway E receives an incoming call, it issues an incoming call request to Expressway C. 5. Expressway C then routes the call to Unified CM to reach the called user or endpoint 6. The call is established and media traverses the firewall securely over an existing traversal connection BRKUCC-2801 2014 Cisco and/or its affiliates. All rights reserved.

However, if Unified CM includes a SIP trunk for other integrations, Unified CM will reject any SIP registration attempts from remote Jabber or TP endpoints, as the register method is not accepted on Unified CM SIP trunk interface Update Unified CM SIP trunk security profile to listen on ports other than TCP 5060 or 5061 (you could use 5560, 5561, etc.) Port change allows for SIP trunk integration AND mobile & remote access Cisco Public SIP Trunk can interfere with remote registrations

This is only required in deployments that include encrypted security profiles (requires Unified CM to be in mixed mode with CTL deployed) The Expressway C server certificate will be presented to Unified CM during the TLS handshake on behalf of remote endpoints with encrypted security profiles Unified CM needs to find a match between the Expressway certificates CN or SAN and the phone security profile name to authorize the TLS registration on TCP 5061 Unified CM phone security profile names cannot be shared across device types BRKUCC-2801 2014 Cisco and/or its affiliates.
