Are you getting analog from a channel bank (using 4 port line cards) or is it a Digital Line Card? If it's the former, obvious, if it's the latter, you will not hear static from a digital signal until it's converted to analog (headset).
If it's jitter (like a digital cell phone (underwater)when it's on the fringe of it's range), than you have network issues which could be 1 of several things.
If it truly is static, try these troubleshooting steps
1.) Did the user shave today and is it rubbing on phone (this happens alot)
2.) Place a call from the outside and leave a voicemail. If it's clear, it's beyond your circuits.
3.) Get phone cord detanglers and check cords.
4.) Check your Power (try plugging your phone into the UPS your NBX is plugged into) and check for quality.
5.) Check packetloss and Jitter levels on phone (hold Mute, then the left and right button directly under LCD simultaneously). Your LCD will change. At this point, press bottom feature button (on business phone, it's the bottom oval button #6 left of Desi Strip). Press the down arrow on the right side of the LCD until you see JittEarly, JittLate. Verify the values are 00 for each, if not, press mute button 1 time, press the number 0, then press feature button number 6 and verify stat's are 0. Press the mute button several times to exit back to normal operation. Place some calls and periodically check these stats by repeating the steps above. Keep a log, and if the numbers you see in packetloss/drops, and jitters, appear to be at high levels, then it's time to look at your infrastructure.
