I have a customer that has 7940 phones and about 3 out of 7 users are having static issues all of a sudden.
First thing I checked was the line cord, swapped out with known working and seemed to resolve problem - get anew line cord. Customer says still happening, can't see anything on 3550 or 3640 VG that would point anywhere. CallManager is registering phones.
Any idea where to look in either VG or 3550 for potential source?
I had a static issues at one of my sites. A lot of users had their handset volume turned up all the way which caused you to hear the echo canceller which could be interpretted as static. I personally was able to reproduce the issue and it seemed to create static at the end of words/sentances, etc.
I fine tuned volume levels on the voice-ports using input gain which allowed people to lower volume on their phones and the problem went away.
Also, to edit the duplex settings on the phone you were in the right place. You need to press **# so the lock icon at the top of the screen changes to unlocked. Then you can press the edit button on SW Port Configuration and type in 100F.

the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
