Hi, I'm looking at getting a Vonage phone line for my 1.5/768 ADSL circuit. I'm completely new to VOIP though and have some questions:
1) How is the voice quality? Is it closer to cell-phone quality than POTS?
2) Are there delays or echos when making VOIP calls?
3) How much bandwidth does a VOIP circuit consume when idle and when in use?
4) Can I have more than one line on my ADSL circuit?
5) Can I use my fax machine over a VOIP circuit? Will speeds be reduced?
6) What protocols and ports does the analog phone adapter use? I want to know how to safely and properly allow this traffic through my firewall.
TIA for answering these. I'm really interested in pursuing VOIP service; you can't beat the price!
thanks, Jonathan
