You can use this snippet to determine whether or not the device has the Telephony feature:

if (getPackageManager().hasSystemFeature(PackageManager.FEATURE_TELEPHONY)) {
    // You can make calls
} else {
    // You can't make calls
}

Beyond that, if you simply want to make sure that your app isn’t installed on any device without the ability to make calls, add the following to your manifest:

<uses-feature
    android:required="true"
    android:name="android.hardware.telephony" />

Please remember that android.hardware.telephony is an umbrella feature, and some tablets may implement sub parts of it, like android.hardware.telephony.cdma or android.hardware.telephony.gsm
