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

  • G.729 (8 Kbps)

Endpoints

  • Cisco 88XX
  • Cisco 78XX
  • Cisco 79XX
  • Cisco 69XX

Communication Protocols

Standard Ports

Typically, NYU uses the following ports to ensure that the SIP endpoints is able to register with the infrastructure:

  • 5060 — UDP/TCP
  • 69 — UDP
  • 6970 – 6972 — TCP
  • 80 — TCP
  • 8080 — TCP

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.
