Vodafone 3G disconnects when Gtalk voice call initiates

Hi,

I just observed Vodafone 3G disconnects whenever a Gtalk voice call is initiated.

I use Firefox/Google Chrome browser to access Gtalk as application version is not yet available for MAC.

I connect to internet on my laptop via Nokia 5230 (tethering).

3G was activated yesterday and I soon observed this as it was working fine with 2G (GSM). One more thing observed was I get a 10.xx.xx.xx IP (private) on my laptop when connect to internet after switched to 3G. With 2G it was a public IP Address.

ip2location or similar website shows a public IP Address though I get a private IP on my laptop. This could be because Vodafone is proxying/nating the 3G traffic and purposefully blocking traffic by detecting Gtalk voice related traffic.

I am from Bangalore and did anyone experience similar issues with Vodafone or other providers?

Thanks,
Meharo

I just confirmed this behavior by testing the same on VPN. When I connect to office network via VPN, Gtalk voice calls goes through and never disconnects. This is because when I connect to office via VPN, everything is encrypted and a proxy at Vodafone can't see what traffic is going through their gateways.

I think Vodafone should not do this as I am anyway paying for my 3G data plans. Also its my freedom to choose Gtalk for voice calls.

may be you should consider leaving the big bad three. [airtel-vodaphone-idea].

I doubt Voda is doing this on purpose.
I have right now Airtel 3G only and we have to wait for some one with voda 3G to verify the fact.
Apart from big bad three we have equally bad sheeps viz ..
BSNL(all India) ,Reliance(only north & Bombay)& Docomo!

I have used BSNL 3g for both gtalk and skype, never faced and issues and it worked fine. Have not tried the same on my Airtel3g yet.

I extensively use skype (voice only) on android phone with MTNL 3G and never faced any issues, even when roaming on BSNL Network
