I recently recieved 6 facetime calls from a random number. Upon further examination there were 5 of my friends in it as well as about 10 random numbers that have out of state area codes.

The other day I received a facetime call from what I assumed was my baseball GC. I believed this because one of my teammates names was on the banner and it said it was a group facetime. 5 minutes later I received 5 notifications saying Facetime ended almost as if someone was spamming new facetime and then ending it. I looked and there are about 20 different numbers every time except my 5 teammates, they were in every one. This spooked me due to the fact that I didn't think i was on the facetime and to see it say call ended made me feel as if I joined it. The text still is red for the facetime but i find it weird I received 6 calls from different numbers other than the contacts from baseball. I saw and old post on this however Apple claimed it was fixed. Is this normal and happening to others?
