Description
Cisco Intercompany Media Engine (Cisco IME) provides a technique for establishing direct IP connectivity between enterprises by combining peer-to-peer technologies with the existing public switched telephone network (PSTN) infrastructure. Cisco IME allows companies that have deployed Cisco Unified Communications Manager to communicate securely over the Internet rather than the PSTN by creating dynamic Session Initiation Protocol (SIP) trunks between the enterprises. By enabling traffic outside of the enterprise to travel over the Internet, Cisco IME extends features and functionality to external calls that have previously worked exclusively within the enterprise, such as video enabled calls, wideband audio support, rich caller ID, presence, and others.
Cisco IME requires the following components: the Cisco IME server, the Cisco Unified Communications Manager server, the Cisco Intercompany Media Engine-enabled ASA, and certificates from the GoDaddy.com website. The Cisco IME server resides in the demilitarized zone (DMZ) at the customer premise and functions as an automated provisioning service. The Cisco Intercompany Media Engine Installation and Configuration Guide describes these components and how to configure them.
To use Cisco IME, you must deploy the Cisco IME solution, including configuring the direct inward dialing numbers (DIDs) in Cisco Unified Communications Manager that you want to participate in Cisco IME. Cisco Unified Communications Manager publishes these numbers to the Cisco IME server that, in turn, publishes the numbers to a server in the IME distributed cache ring. All Cisco IME (peer) servers participate in the IME distributed cache ring and store data in encrypted form. The Cisco bootstrap servers also reside on the ring and distribute configuration information to the Cisco IME peer servers.

Installation/Upgrade (Migration) Considerations
To use the Cisco Intercompany Media Engine, you must install and configure the Cisco Intercompany Media Engine server.
You can install Cisco Intercompany Media Engine 8.0(1) on one of the following servers:
•
•
•
•
•
For software installation procedures, refer to the Cisco Intercompany Media Engine Installation and Configuration Guide.
For server capacity information, refer to the Cisco Unified Communications SRND Based on Cisco Unified Communications Manager 8.x.
Serviceability Considerations
The Real Time Monitoring Tool runs on both the Cisco Intercompany Media Engine server and the Cisco Unified Communications Manager servers to provide information about system and feature health.
You can install RTMT onto a client machine from only one product type—Unified Communication Manager or Cisco Intercompany Media Engine. Installing RTMT client from different product types on the same client machine is not supported.
For information on installing RTMT on a Cisco Intercompany Media Engine server, refer to the Cisco Intercompany Media Engine Installation and Configuration Guide.
For information on installing RTMT on a Cisco Unified Communications Manager server, refer to the Cisco Unified Real Time Monitoring Tool Administration Guide.
This section contains information on new performance objects, alerts, and alarms for both the Cisco Unified Communications Manager server and the Cisco Intercompany Media Engine server.

BAT Considerations
The Bulk Administration Tool (BAT) gives the administrator a fast and efficient way to insert and delete the following Cisco Intercompany Media Engine (Cisco IME) components in batches, rather than performing individual updates through Cisco Unified Communications Manager Administration:
•
•
•
•
•
•
•
•
You can add and delete these elements using the new menu option Bulk Administration > Intercompany Media Services.
CAR/CDR Considerations
You can use the CDR Search for Different Call Types window (CDR > Search > Call Types) in Cisco Unified Communications Manager CDR Analysis and Reporting to get information about the following call types:
•
•
•
•
•
•
Security Considerations
For information on port usage on the Cisco Intercompany Media Engine server, refer to Cisco Intercompany Media Engine Release 8.0(2) TCP and UDP Port Usage.
AXL and CTI Considerations
No AXL or CTI considerations exist for this feature.
User Tips
Users dial numbers as usual. If the system has learned Cisco Intercompany Media Engine routes, calls automatically get routed over dynamic SIP trunks. If fallback is configured, calls may fallback to the PSTN if the quality of the call falls below configured levels. After fallback, the call remains active, but the user will lose rich media, such as video connections.
