Using Multiway with Cisco TelePresence systems

Using Multiway™ with Cisco TelePresence systems

Multiway™ is a Cisco TelePresence feature that allows the user to transfer an established point to point call to an MCU, so that more participants can join the conference.

Multiway system requirements

Your deployment must have the following components:

  • Cisco TelePresence endpoints that support Multiway™
  • Cisco TelePresence Video Communication Server (VCS)
  • Cisco TelePresence MCU

Your deployment may also include a Cisco TelePresence Conductor.

Below are two sections summarizing the supported software versions and configuration required on the components: one section for a deployment with TelePresence Conductor and one section for a deployment without it.

For more detail on deploying Multiway across your solution, see Cisco TelePresence Multiway Deployment Guide and the supporting documentation for each of the components.

Multiway with TelePresence Conductor

The following table summarizes the configuration of the components if there is a TelePresence Conductor used in the setup.

System Supported products and software version(s) Configuration
Endpoints that can initiate a Multiway conference:
  • Cisco IP Video Phone E20 (TE1.0 or later)
  • Cisco TelePresence System EX Series:
    • EX60 and EX90 (TC4.2 or later)
    • Cisco TelePresence Touch for EX Series (TC4.2 or later)
  • Cisco TelePresence System Profiles using C Series codecs:
    • C20 (TC3.0 or later)
    • C40, C60 and C90 (TC4.0 or later)
    • Cisco TelePresence Touch for C Series (TC4.2 or later)
  • Cisco TelePresence System MXP Series:
    • MXP must be running F8.0 or later
    • F8.1 or later is recommended for mixed H.323 and SIP Multiway conferences
    • F8.2 or later is recommended if TLS is used to connect the MCU and Cisco VCS
To initiate a Multiway conference, the endpoint must be pre-configured to support Multiway.
Endpoints that can join a Multiway conference, after it is initiated:

H.323 endpoints

  • Cisco TelePresence System MXP (F8.0 or later)
  • Cisco TelePresence System EX Series (TC4.2 or later)
  • Cisco TelePresence System C Series (TC4.0 or later)
  • TANDBERG 150 MXP (L6.0 or later)
  • TANDBERG Classic endpoints (must have encryption disabled)
  • Sony PCS G50 and Sony PCS TL30
  • other H.323 devices that support the routeToMC Facility Message

SIP endpoints

  • Cisco IP Video Phone E20 (TE1.0 or later)
  • Cisco TelePresence System MXP (F8.0 or later)
  • Cisco TelePresence Movi (3.1 or later)
  • Cisco TelePresence System EX Series (TC4.2 or later)
  • Cisco TelePresence System C Series (TC4.0 or later)
  • other SIP endpoints that support the SIP REFER message
No Multiway-specific configuration is required for an endpoint to be invited into a Multiway conference. However, the endpoint that initiates the conference must be pre-configured to support Multiway.

  2. Configure a Multiway conference alias.

Multiway without TelePresence Conductor

The following table summarizes the configuration of the required components if there is no TelePresence Conductor used in the setup.

System Supported products and software version(s) Configuration
