Hi,I have sent a magicjack device to family in Mumbai who have MTNL isp service (not sure of the plan they are on at this time) and after the MJ was connected to the computer and software installed, they get a dial-tone but when calling a number in USA it does not connect. When I call the MJ number I get to MJ voicemail. So initially I thought it may be a firewall issue but it was not as the firewall was turned off and still didn't work. Has anyone with MTNL service successfully got MJ working in Mumbai? if so, was there anything special that needs to be done?Thanks in advance.
