Bad Video Quality in Sorenson VP-200 to PolyCom ViewStationEx Calls and vice-versa


         I work at National Technical Institute of Deaf, RIT, NY. In our campus there are many Sorenson VP-200  and
PolyCom ViewStationEx installed. I face issues in making calls from Polycom to Sorenson or vice-versa. I am able to make a call using the IP, however the call quality is really bad. There are lots of video jitters and the video hangs very frequently.

     I have tested it on both, local LAN (both Polycom and Sorenson within same subnet) and remote calls. The call qualities are really bad in both cases.

If connected to a Cisco Switch, make sure the EX is not set to Auto for Speed or Duplex.

you cant answer numerous calls on this system - you will need to set up a dial in number on a phone bridge provider and have all participants call into that number and then all of you will be in same conference call. this is best quality and the most managable way to do this. i am sure your phone provider can help you set this up. R if i remember correctly is for redial

Connecting a polycom

No, i don't think si. The polycom needs an ethernet connection to a router. You might get this working by putting the 3g card into a PC and enabling connection sharing, however even if you got it work itsd a bad solution in terms of:
- Cost
- Reliability
- Security.
ADSL would be better.
