I was using comcast cable and was able to have vedio and voice conversation to India. I changed to DSL and since then I am not able to have any of them. Can some one guide me.
You're wrong about that. 3.0 Gbs means 3 *Gigabits* per second. The best
cable does is 3 *Megabits* per second (3Mbs). Also, that is *download* speed
only; upload speed is a "measly" 256Kbs (kilobytes per second). Upload speed
is just as important for video conferencing as download speed. DSL comes in
to "flavors" - ADSL or Asynchronous DSL - with download speeds up to 1.5Mbs
and upload speeds up to 384Kbs and SDSL or Synchronous DSL - meaning upload
and download speeds are the same and are up to 1.5Mbps. SDSL would work
*much* better than cable for video conferencing *if* both parties had it and
at the highest speed available.
It is much more likely that the original poster's problem is caused by a
firewall or other port blocking either by his ISP (DSL provider) or some
setting of his DSL modem.
