Make sure the mute isn't on
First, and I'm pretty sure you've checked this but make sure the "mute" key is not inadvertently activated as it's right above the "call" button and if you keep your finger on the call button a little too long when activating a call, you may be hitting the "mute" button when you do not realize it.
I'm sorry that I can't give you the exact procedure for a factory reset for this particular phone. I know that ZTE has at least three procedures for a hard reset, I'll give you those three and I'm fairly certain one of them should work ...remember to back up anything you want to save as you are putting the phone back to its factory condition:
1. While the phone is turned off, press and hold the Volume Up and Volume Down buttons together. Then, while still holding them, press and release the Power button (keep holding the volume buttons). The phone should turn on and a menu will appear. Press the Volume down button to navigate to the Recovery option. Press the Volume Up to select (if that doesn't work, use the Power button to select). A yellow triangle and an Android logo will appear. Press the Volume Down and Volume Up button together and a recovery menu should appear. Use the Volume buttons to move to the Wipe data/Factory reset option and then press Power to select. Again, use the Volume Down key to choose "Yes" and press the Power button again to select.
2. While the phone is turned off, press and hold the Volume Down button. Then, while holding, press and release the Power button. A menu should appear. Use the Volume down key to go to Clear Storage. Use the Power button to select the option. Then when asked to confirm, press Volume Up for Yes.
3. While the phone is off, press and hold down Volume Up + Home + Power buttons at the same time. Then release the buttons when you see the Logo. Use the Volume Down button to scroll the menu and the Home or Power key to select. Choose the Wipe data/Factory reset option. Then Select "Yes" to delete all user data. Then reboot the phone.
And, finally, Walmart has a 15-day return period so you may just want to pack it up and exchange if for another one (if you purchased it at a store) ...or if you could do without a phone for awhile during the shipping back and forth if you bought it online.
