Elastix: Incoming callers hear ringing and staff cant hear anything

New installation of an Elastix phone system and randomly, at least once a day - and on different extensions - incoming callers are hearing a ringing on their end. The ringing is loud and our staff cannot hear the user on the other the end. The incoming caller hangs up and calls back and the conversation is fine.

Phones are 10.250.20.X
Data is on 10.25.40.X

elastix 2.4.0 ( I was looking at Linux version - Unfortunately thats not the part I need help with) :smile:
