You can calm down, Do you have any proof you've been hacked?  This appears to be an SQL Injection attempt, I started seeing this yesterday!

Here is what I had in my logs and what the packet has in it:

2017-02-27 18:40:20.451831 [WARNING] switch_core_state_machine.c:687 a7c86b62-4dbf-4609-8bc2-3b6a38e2686a sofia/internal/‘hi'or‘x’='x'@190.10
