Bet other operators follow this :D

I for most part of the day spend my time glued to a computer monitor for work
and hence tether my phones to Home Wifi.

Don't use my phone for anything other than voice calls and the occasional sms.
Whatsapp et al work over Wifi only.
 
I am sure their application to detect ports is going to fail to detect non-VoIP traffic on other ports

Then people will complain about high deduction.

And then customer care will say - "sir you used VoIP and hence charges are correctly deducted!"
 
all traffic of a VPN goes thru a single vpn port encrypted end to end. hence they cant packet sniff to figure out what traffic it is. there is absolutely no way for them to knw what you are doing once encrypted.
 
what an idiotic move , they will know it's it's voip cause voip protocol transmits over sip like sip:ip of voip well the solution is to use openvpn and configure it to run over port 443, but i guess as posted above post paid customers won't have to suffer but will call 'em to confirm it.

edit : i use CSIPsimple on android and it has a inbuilt feature to mask voip as https traffic it is the most secure Voip client out there.
 
too bad... it would be a risky business to run as you would need to keep logs like for ever along with proper identification of all users.
 
encryption is also an issue over mobile networks which are already slow for the most of us. plus, governments around the world do not like it because it takes control out of their hands. things could get ugly if some fucker in the government decides that vpns are a threat to national security.
