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!
