Bandwidth requirement for voice calls

[Rhuban Neer Pandi]

Hi All,

Need expertise advise on the following concern about voice call.

1. Bandwidth requirement for video call across all other endpoint(using Polycom / Lifesize end point at their end)

    a)Standard Video

    b)1K HD Video

    c)4K HD Video

2. Plus can we determine bandwidth required for all the following below:

a. 1 to 1 VC  end point ( Cisco TP – Cisco TP)

b. Bridge call  ( Cisco TP to Polycom / Lifesize)

c. 1 to 1 VC end point ( Cisco TP – Polycom / Lifesize)

There's a good table that shows the bandwidth requried for different resolutions on Page 121 of the TC7.2 Admin Guide for some of the Cisco endpoints (screenshot below).

A voice call is just 64k.

Thanks for the info Wayne. I missed out information about the endpoint.

Client using CTS 3010.  Acoording to datasheet it says 

11.9 Mbps (1080p, 30 fps best motion handling), 10.1 Mbps (1080p, 30 fps better motion handling), 8.8 Mbps (1080p, 30 fps good motion handling)

6.4 Mbps (720p, 30 fps best motion handling), 4.5 Mbps (720p, 30 fps better motion handling), 3.1 Mbps (720p, 30 fps good motion handling)²

My question is does the bandwidth required for both ways or only one way?

And I'm aware CTS 3010 doesn't support 4K video.
