Phone Calls won't work

Once again my phone is broken - this time its a strange problem. I have been out of the US and i just reactivated my verizon account yesterday.

Everything else on the phone works - but when i go to make a phone call, i hear nothing.

I can receive phone calls and apparently people can hear me but i also hear nothing on my end. Any ideas whats going on? Are there any settings in the phone i need to change?

Verizon tech support couldnt help me and told me i should just upgrade to another device... dont want to do that

Get verizon to fix it. definitely a verizon problem.

actually. go to media and play a song through your handset.
if it works then it is verizons fault.
