Cisco Unified Communication Trusted Firewall Control-Version II

Cisco Unified Communication Trusted Firewall Control-Version II

Last Updated: December 20, 2011

Cisco Unified Communications Trusted Firewall Control pushes intelligent services onto the network through a Trusted Relay Point (TRP) firewall. TRP is a Cisco IOS service feature, which is similar to the Resource Reservation Protocol (RSVP) agent. Firewall traversal is accomplished using Session Traversal Utilities for NAT (STUN) on a TRP colocated with a Cisco Unified Communications Manager Express (Cisco Unified CME), Cisco Unified Border Element, and Media Termination Points (MTP).

This release introduces the following features:

  • Noncolocated firewall for UC SIP trunks
  • Support Firewall traversal for Cisco Unified Border Element call flows in which the media flow through the Media Termination Points such as MTP, Transcoder, or Conference bridge with Trust Relay Point (TRP) enabled.
  • Firewall traversal for additional Cisco Unified Border Element call flows using STUN.
