So this is an extension of a topic I started in a different place. I have replaced the system and sets at this office space three times now and I am kind of over it.

Details: low volume on lines from time to time (butt set too). The customer complains of "the batteries going dead". Translation, while on a call the volume all of the sudden drops off. Other times its bad from the start.

So I run some tests with my meter and the lines removed from the system. I then try a different meter just to see if I am getting the same readings and I do. Just to satisfy the possibility of my readings not being accurate . I call in a tech from the provider. I ask him to test the lines and I give him a little chart for documentation. His response to me "those tests are only good for dedicated lines".

OK so now I am thinking they are using either a multiplier or a channel bank in the closets for this building.

His test results follow.
