Bridge: Features

The Cisco WebEx Telepresence bridge service enables WebEx Telepresence users to do the following:

  • Conference up to six (for 6-port) or 12 (for 12-port) video and/or audio parties together. For example, a 6-port conference could include a combination of four video participants and two audio participants. Once the bridge is full, new users trying to access the bridge hear an audio prompt indicating the bridge is full. New parties cannot join the bridge until a port becomes available.
  • Accept video calls from WebEx Telepresence users as well as compatible H.323/SIP-based video devices.
  • Accept audio-only calls from any PSTN landline or mobile phone.
  • Share data presentations with other WebEx Telepresence devices (including Cisco Jabber Video) as well as SIP/H.323 devices.

Data sharing among WebEx Telepresence devices uses the IETF standard known as the Binary Floor Control Protocol (BFCP) or RFC4582. Non-WebEx Telepresence, SIP-based devices use BFCP, while H.323 devices use the ITU standard H.239.

The WebEx Telepresence bridge service supports up to 720p30 resolution and up to 2Mbps bandwidth per participant.

The actual resolution and bandwidth are limited by your device capability, the type of WebEx Telepresence subscription, and your own bandwidth from the device to the WebEx Telepresence data centers.
