Which is better for video conferencing, ISDN or IP?

Polycom is a company that provides ip phones and Video conferencing equipment

Can you use a polycom vsx aptz-2p camera with an hdx 8000

It's probably your phone-line that causes the problem. The fax-module in your machine needs a 100% analog phone line. HP garantees nothing when using IP/ISDN/PABX-lines. Try lowering the baud rate, turn off JBIG compression and error correction mode, but if the problem remains, you better replace your phoneline.

Sounds like you are missing AAA author for your PPP sessions. Without seeing your config, it is a bit hard to give you more help.

Go into wap settings in your phone and add new connection and use these settings.

Check out the following things:-

1. When dialing a ISDN number, be sure that the call preference has not been set to IP H.323 on the home screen just below the dialing field.

2. Check with your service provider that outwards dialling have been enabled on the lines provided to you.

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.

No most system are maxed on the phone ... but if you had a panasonic system they are know for multi conferencing.

hi artit,

I had the same problem with heavy packet lost after 10 minutes connection between Singapore and USA. We are using ADSL line and Sony PCS-G50 for video conferencing. After a much trouble-shooting, we identified that the nature of the problem lies with the Internet Service Provider's back-end server. The server has difficulties handling large and constant data packets. This could be due to the reasons that ISP using routers with more hops and small pipes. We immediately changed the ISP to a more reputated one (with better infrastructure) and now, we have a much better quality video.

recheck the spid on your ISDN lines and make sure the order is correct
