Just need some info has anyone installed a IPO with nortel T7316E phones everything is working and has been for 1 month but recently customer is complaning about crackling noise on phone when talking. reset system and cleared issue but now same issue on diff phone . oh system does have a T1
 
Have multiple customers with IP Office 500 v2 on 7.0(5) and higher firmware with T7316e Digital phones on the main unit and expansion modules both with PRI-T! and Analog Trunks and no problems reported.

Suggest testing your trunks. Is the problem related to incoming, outgoing or bothway calls? Are multiple phones having problems or one phone with bad handset cord.

Do any of the telephones have a handset untangler installed on them? They are notorious for causing static on calls.
 
I had the same problem upgraded switch to 7.0 (23) problem disappeared.
 
There was an issue with Nortel phones producing static if the volume is turned up high. I think only in 7.0.23 and the patch is supposed to fix it.
