Hello Ashinusa,I have the same airtel connection as you have, the same modem you are using, Linksys phone adapter from Vonage and D-Link's wireless router. In my phone adapter(Linksys) the PHONE LED doesn't become stable green, so I am not getting the dialtone from my phone and thus unable to place a call. I was getting the dialtone when I had not connected the wireless router (Dlink) and was able to place calls to U.S. and Canada.Can you help me with the settings of my coonections. Airtel people are not able to help. Say that their internet is working fine and they know nothing about vonage.Thank you in anticipation,Harman in Chandigarh
