Answer 1

Although, Xcode 9 is announced officially, still there isn't VoIP on the capabilities.

I solved my problem by opening Info.plist as a source code and adding "voip" to UIBackgroundModes manually.

<key>UIBackgroundModes</key>
<array>
    <string>audio</string>
    <string>voip</string>
    <string>fetch</string>
    <string>remote-notification</string>
</array>
