     I just had cable/internet installed and assumed most any Cable/DSL ISP would offer the ability to use telephone service via VoIP  
      According to my new cable ISP they are not/can't offer it 'right now'!!
      No one at the cable co can seem to explain why it is not offered right now but they say that they are 'working on it'
      Does VoIp telephone service "consume" more bandwith and possible make it a feature that the new cable/internet supplier may not be in a big hurry to "make available"???

Hi gmd024,

I don't think it's a bandwidth concern, more an issue of the amount of technical work required in order to implement a VoIP system for consumers.

If you want to use VoIP, then I suggest you sign up with one of the large number of VoIP SIP providers.  The most popular is FWD, available at http://www.pulver.com/fwd    Unfortunately FWD doesn't allow you to make PSTN calls (except to free numbers), but there are a number of others who offer VoIP-PSTN termination.

Does your cable ISP provide your phone service as well, or is that seperate?  If they did, they'd need to set up a VoIP PBX that is connected to their telco switch.  Any calls to your number would have to be routed by the switch to the PBX, and then passed on to your SIP hardphone/softphone.
Unless there's a real demand for this/financial benefit, I would guess they wouldn't leap into doing it.

If you could explain a little more about what you want to achieve, I'll do my best to advise further.

Glad I could help.  Sorry that it wasn't exactly the answer you expected :-)

Good luck with Vonage.  VoIP works well, unless you have bandwidth (more specifically packet loss and latency problems).

Take a look at http://www.testmyvoip.com/  - it'll tell you exactly where you're having troubles :-)
