I am using my SIM in the Data Card, so I cannot receive calls from my Computer. Although the product has feature to receive calls via computer Mic, but it never works for me.Whenever the calls comes, the BSNL Software gives alerts and I can hear the ring on my Headphones. It also disconnects my Connection!! grrrrrI keep getting many missed calls from this number - +919448355447 I tried calling this number from my other Mobile, but the call doesn't connect.Is this BSNL Promotional Call service? or any other important BSNL Server which wants to reach me to tell me something important related to my BSNL SIM Card?
