I have a problem with bandwidth consumption between Unity Connection 7.1.5 and a remote 7942 phone. For whatever reason, there is a tremendous amount of data between transmitted between these devices, about 10mb every 15 minutes. Using Netflow, I see it's all UDP traffic between the unity server and the telephone. Traffic to the phone is coming in on port 22478 and 23866. Traffic from the phone to Unity is on UDP ports 17670 and 18902.
Any ideas on what is happening or how to stop the traffic?
