Messenger Call Failed

Hi,

I just wanna know if this happens to other as well or if there’s any work arounds that i can try.

Whenever i try making a phone call to someone using messenger, it always tells me that its “Contacting” Even though I’m connected to the internet.

Same goes if someone is trying to call me (voice/video) —i will receive a notification telling me that there was a missed call but I’m always online and connected to the internet

Hes the only person that I can’t call and he couldn’t call me although we can chat and send media files. It only started happening two days ago.
