Movi works in conjunction with other Cisco videoconferencing infrastructure products, primarily the Cisco TelePresence Video Communication Server (Cisco VCS), the Cisco TelePresence Management Suite (Cisco TMS) and provisioning. The References and related documents section contains a list of documents referred to in this guide. Cisco TelePresence Movi for Windows is a certified Windows 7 application. Cisco TelePresence Movi Administrator Guide (4. 1) Page 5 of 29 Prerequisites Prerequisites Infrastructure requirements Movi requires the Provisioning option on the Cisco VCS and in Cisco TMS to be enabled. Product Cisco TelePresence Management Suite (Cisco TMS) Cisco Video Communication Server (Cisco VCS) Version 12. 6 or later recommended X5. 2 or later recommended PC requirements Processor A processor supporting SSE3 (such as Pentium 4 Prescott) or better.

Cisco TelePresence Movi Administrator Guide (4. 1) Page 17 of 29 How communication works How communication works This section includes general information on Movi's main types of communication and is essential for the subsequent section, which describes specific messages. SIP communication Movi communicates with the Cisco VCS using the Session Initiation Protocol (SIP). Subscribing, registering, presence querying, call invites--all communication except video and audio, is done in SIP. SIP messages are sent using TCP, with or without TLS encryption depending on the Transport configuration in the Advanced settings. The default SIP listening ports used on the Cisco VCS are n n 5060 (unencrypted) 5061 (encrypted) These are both configurable. Go to VCS Configurations > Protocols > SIP > Configuration to change the listening ports. Note: If you change the SIP listening port number on the Cisco VCS, you must also configure the Movi clients to contact the Cisco VCS on this port. These ports are handed over to the Movi client by the TCP stack and are not configurable. To enable communication with endpoints and other devices that rely on H. 323 and do not support SIP, interworking on the Cisco VCS can be used. Media communication Media data is transferred through up to nine UDP links (ports). There are at most five media streams: n n n n n Audio Primary video Secondary video (presentation sharing) BFCP (management of presentation sharing/duo video, see below) Far end camera control (FECC) With the exception of BFCP, each of these streams requires two links: one link for RTP packets and one link for RTCP packets. The SRTP protocol is used if encryption is enabled. Port ranges The default port range for Movi to receive media is 21, 000-21, 900. Add (or select) the configuration's Media Port Range Start and Media Port Range End. Note: A minimum range of 10 ports must be configured, or Movi will revert to default. To configure: Cisco TelePresence Movi Administrator Guide (4. 1) Page 18 of 29 How communication works 1. Note that in both cases, the port numbers used will be consecutive, but chosen randomly within the specified range. Duo video­Binary Floor Control Protocol (BFCP) Movi supports BFCP for handling the control of duo video. Movi uses the same ports as for audio and video for this communication. On the Cisco VCS, a port will be chosen at random from the same range that has been assigned to the media links. Traversal calls Media links can be established directly between the two endpoints in non-traversal calls, or between Movi and the Cisco VCS in traversal calls. As a general rule, non-traversal calls are defined as calls between two participants that are on the same network and do not require interworking. Note that SIP to H. 323 calls require interworking and are therefore traversal calls irrespective of whether the endpoints are on the same network. For detailed information, see the latest Cisco VCS Administrator guide. Media routing Cisco TelePresence Movi supports Interactive Connectivity Establishment (ICE) for better media routing. ICE will be used if enabled both in Movi and the far end. Media routing without ICE When the ICE protocol is used in a call, media links are established directly between the two endpoints in non-traversal calls, or between Movi and the VCS in traversal calls. As a general rule, non-traversal calls are defined as calls between two participants that are on the same network and that don't require interworking. [. . . ] Jitter is a continuously calculated estimate of the mean deviation of the difference in transit time of adjacent packets. The transmit jitter information is based on RTCP reports from the far end. High jitter affects the call quality and is usually indicative of poor network conditions.
