Overview
Audio and Video Conferencing solutions supported by NYU IT Collaboration include in-room, desktop, and web-based video conferencing, as well as WebEx services.
For additional information on available video conferencing services, please visit Introduction to NYU Video Conferencing Services.
Video Teleconference Endpoints
- Units must be registered with NYU-Net to leverage NYU IT services such as conference bridging
- Units must be compatible with NYU IT supported codecs and protocols (see Supported Codecs section below)
- Proprietary software such as Skype is not supported
Point-to-Point and Multipoint Sessions
Point-to-point and multipoint calls are supported for Video Teleconference units. There is an additional cost for the license to host a multipoint call locally from the unit.
NYU IT offers free bridging services for internal rooms and external guests.
Conference Bridges
The NYU Conference Bridge support up to 100 participants simultaneously using anything from a desktop phone, local computer, or a conference room with a video codec. Individual Virtual Meeting Rooms (VMR) can be setup for either a one-time use or a recurring meeting. There is no cost associated to use the NYU Conference Bridge.

Supported Codecs
Audio Codecs
- G.711
- G.722
- G.722.1
- G.728
- G.729
Video Codecs
- H.261
- H.263
- H.263+
- H.264
- H.264-HP
- H.265
- H.239
Communication Protocols
- H.323
- SIP
The minimum codec requirement is H.261 and G.711. However, this minimum will not provide the High Definition (HD) audio and video quality that most users expect of modern video conferencing technologies.
Please note that a single codec does not support more than four additional endpoints without the use of the bridge.
Standard Ports
Typically, NYU uses the following ports to ensure that the Video codec is able to register with the infrastructure:
- 1719 — UDP
- 1720 — TCP
- 5060 — UDP/TCP
Additionally, each vendor has their own set of required ports for video. Please consult the Admin guide provided by the vendor for a full list of required ports.
Secure Real-time Transport Protocol (SRTP)
STRP is not supported at this time.
Transmission Speed
512k speed transmissions or better are required for higher quality video.
Quality of Service
Please contact Network Engineering at noc@nyu.edu for Quality of Service (QoS) availability and recommendations.
Glossary
- Codec – A device or program encoding or decoding a digital data stream or signal. Codecs are used in video conferencing, streaming media, and video editing applications
- Point-to-point – A communications connection between two nodes or endpoints
- Multipoint – Simultaneous communications among three or more endpoints
- Secure Real-time Transport Protocol (SRTP) – Intended to provide encryption, message authentication and integrity, and replay attack protection to data in both unicast and multicast applications
- Quality of Service (QoS) – The ability to provide different priority to different applications, users, or data flows, or to guarantee a certain level of performance to a data flow.
- Virtual Meeting Room (VMR) – Conference room on the NYU Bridges
