I try to call sum one in india who is using gtalk how is dat he can hear me and i cannot hear him??

Use proxy sever to use GTalk,search from google you type there proxy server and select your proxy sites.

i suggest you that if its logout go to the gtalk settings on that click account settings then give your username and password in to it and try sign in again. If still problem you can download the another gtalk applicaitions like fring, nimbuzz these are also can use to chat in the gtalk

Concerning to Gtalk (Voice-over-IP) :
1) The credits does not have expiry restrictions, which means as long as your account still own sums of credits, then it is still valid.
2) Rates when using VoIP & plug-in to get low rates, visit this link: http://www.google.com/chat/voice/
3) For more info & question, see FAQ via this link: http://www.gtalk2voip.com/faq.shtml

Unfortunatly gtalk is unavailable for your phone, however you can use gtalk features with a program such as GoTalkMobile: http://www.gotalkmobile.com/
or Talkonaut: http://www.talkonaut.com/home.shtml

In gtalk, i am able to hear the voice from other side and they are not able to hear my voice.. what could be the reason.. Can you suggest some solution.

since you are facing problem with all the IM's. check the connection speed. sometimes even EDGE is not enough for voice chat. try it with a better bandwidth connection.

Change the Ram

Can you hear all other sounds,i mean sounds from music player?

Disable your internet security software and then try calling.

jus try by using sim cards,sum times reliance sim works
