This question already has an answer here:
Regarding below post from 2014, I have the exact same problem with every call I make to Lebanon. How do I stop this? Is it a bug? I have factory reset my phone and it's still happening.
My wife called a GSM/3G number abroad and the call was dropped. She called again and she could hear the whole conversation repeated with the other party but with blank period from her side of the conversation.
How can this explained?
The call originated from Saudi and terminated in Lebanon.
