VP number change have nothing to do with quality of connection. Actually the VP number is NOT telephone number. It is VIDEOPHONE number. Big different, also, Videophone have nothing to do with telephone company. BUT it has to do with associating with Public IP address.
When you see poor video, usually it is caused by poor networking connections not the VP itself as most people assumed.
Check all network cable connections, loosen cable from Modem/router/VP/PC can cause slow down and video freezes. Sometimes Internet service company have network outrages, that is why it is good idea to contact them first to see whats going on with Internet connections. If they said they are experiencing technical difficulties in your area, then it is wise to be patience and wait for them to restore the outrage. Changing your VP setting will do no good and can make it worse, so don't bother with it.
Its very important to pay attention to speed on your VP. You should be able to send between 248 and 252KBPS, and recieving speed around 500KBPS with at least 25 FPS on both ways. If it is less than that, don't bother trying to change any setting on your VP except adjust VP speed to 256 as send speed, 512 as recieve speed. If your VP already set to 256 (top) and bottom at 512,
then next is run speed test using your computer. go to
Speakeasy - Speakeasy, Inc. - Broadband, Voice and Data Services and select the cities that is farthest froim you. Pay extra attention to upload speed which is the most common problem. If it is less than 350KBPS, call your Internet company to check the connection. You should be getting that speed at least for what you pay for.
Also, sometimes router or modem firewall becomes enabled meaning protection is on for the Internet traffic to your VP will slow down and cause freezes. If you need help disable the firewall for the VP, call Tech support and they will help you how to set up the router and modem. If you see Modem and VP and think it is ok, really you can not see the firewall setting until you go inside the modem and set up. FYI, sometimes Internet service company forced upgrade the software on your modem, then the firewall will automatically turned on, end up poor video, black screen, etc. That is something we all don't have control over.
Also, it is important to check other end VP to see if they might have bad connection. If they have poor connection, it will always affect your VP video quality. It takes ***BOTH*** end with excellent connections to make VP quality awesome. Make sure their VP-100 speed setting is set to 256/512, if they set to 256/256, or 512/512, it will cause poor video quality.
If everyting looks good, just call Sorenson Tech support and let them observe your VP. They will make decision on what solution to use.
I think I figured it out. we changed the phone number on our VP. that made it not work. I THINK.
