The Polycom VVX300: Where did the ghost calls come from?
Q:
We are using Polycom’s VVX300 phones. We have gotten lots of ghost calls and I wonder where those calls came from?
A: The ghost calling is usually created by uPnP or SIP ALG that might be enabled on the router. Be sure to have a password listed on the PBX for your extension.
