electrical interference (noise) detected while fluke testing cat 5 wired data circuits?

Question by Zart: electrical interference (noise) detected while fluke testing cat 5 wired data circuits?
We have been testing our internal wiring in advance of the VOIP deployment with a Fluke tester.
Most of the wiring circuits are indicating pass results however, a few of them are indicating noise detected.
The noise is being caused by electrical interference somewhere in the path from the LAN jack to the termination block in our server room.
How significant could this problem be in affecting VOICE quality if any?
Are there tolerances in the technology that can absorb this interference?
I will add however, that data transmission thru these same circuits flows un-impeded in that the connections are maintaining 100 mb flow and POE capability.
Perhaps a reference to a subject mater expert can help me as well......if you know of one.
Thanks in advance.

VOIP is just data when it is in the CAT 5 world. If your data flows fine, then the noise isn't a problem (it doesn't matter what the data is).

Dual Action Automotive Electrical Test Connector No Bezel






This video shows the dual action electrical test connector with the bezel removed. This allows you to see the inner workings of the connector. As the video clearly shows, the product connector is simply placed into position and the dual action connector does all of the work. It draws the product down perfectly square. This eliminates any chance of product pin damage due to excessive force on 'side-loaded' pins. The dual action connector requires virtually zero insertion force and ensures you do not damage the product under test with your electrical test equipment.
