Unknown caller ID

Hello,

 

We have an issue with our SRX20 Telepresence. The IP of the TP is for example 202.14.13.XX

 

1. We always receive a call from an unknown caller ID, I think its a loopback call. The number would always be in 3 digits.

111@202.14.13.XX 

222@202.14.13.XX

333@202.14.13.XX

888@202.14.13.XX

How can we stop this?

Thanks.
