Overview
NYU IT Unified Communications SIP endpoints supported by Cisco Unified Communications. For more information, please visit Telephones and Mobile Devices.
Unified Communications SIP Endpoints
- Units must be registered with NYU-Net to leverage NYU IT services such as interoffice calling
- Units must be compatible with NYU IT supported models and protocols (see Supported Codecs and Endpoints section below)
- Network Engineering requires audio endpoints to be on NYU-Net Voice VLANs for security reasons
- Proprietary software such as Skype is not supported
Endpoint Features
- Point-to-point Calls
- Conference Calls
- Voice Mail Box

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
- 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.
