The other QQ is not online voice calls can get through it
Finally, the voice prompts you to call the phone no one answered
You will show up after the ringtone, but no one will pick up, will always ring, no one then after a while to remind you that the other side is not online
Is not possible, because the other qq program is not open, so the other party will not receive your invitation, so he can see on the line.
