[cisco-voip] bandwidth restrictions for MRA clients - necessary or not?

[Lelio Fulgenzi]

Thanks Eric. 

I had a similar discussion with a Cisco engineer. Basically, let Jabber figure things out. Which is all fine and dandy, until you read that Canada pays some of the highest fees for mobile data in the world. lol. 

There are not many unlimited data plans available, and a simple 10 minute video call at 10mbps (using 5mbps for calc) could probably use up 3gb of data traffic. 

But then, I don't want to impact quality for Jabber clients on wifi connections. 

I'm guessing that I might go with leaving device mobility out of the picture for now and ensuring video calling is disabled while on mobile networks.

Jabber apparently monitors packet loss and sets the video rate accordingly, which is why the quality starts out really low and them improves with the call. I don't think any of the phones do that, but I believe the 8845 maximum bandwidth is 2mpbs.

quick question... how are people restricting the video/audio bandwidth for Jabber MRA clients or physical phone MRA clients for that matter? 



we have not had to use locations or enabled mobility (i think that's the IP Address based feature) since we have high speed, low latency WAN links to our locations. 



is it even a problem that I need to consider? 



i'd like to make sure we have the best video quality while on-campus (including those connected via high speed WAN links), so i've set the default bw to 10mbps. 



i'm wondering how that will impact MRA clients.
