URGENT: GOOGLE VOICE

[ModmyPPC]

How do I get to recieve calls with google voice.

I have google voice on my phone and its the same account on my google voice account.

It says whenever a person calls "the google voice subscriber is not avaiable please leave a message after the tone."

I can make calls fine send texts but It wont ring when I recieve a call I just get the voicemail.

please give me the steps to fix this.

It needs to be done ASAP!
