Default [Q] Calling problem after installing the official Miui v5 4.4.11 ROM

Hi guys I really need your help !!

I have a Samsung galaxy S3 (GT-I9300) and I installed the official Miui v5 4.4.11 rom on my device. Every thing is ok except I cannot receive or
make calls. My cellphone network is recognized by the device but I don't make or receive calls. I will appreciate any help. Thanks
