Hi, I have recently moved a Lifesize Team 200 from one room to another, and in the new room, I have it set up to take line in and line out audio, not using the Lifesize telephone unit. I have reconfigured the administrative setup as required. All seems to be working fine, and in and out levels are quite good, but I am hearing incoming audio from what must be a speaker internal to the Team 200 unit. I can't find any mention of it in the documentation. Is there a step I missed in the configuration that will disable the internal speaker? I would appreciate any hints.
