Hi

Has anyone experienced a loud hissing noise during some calls on 3.1(65)?? Sometimes too loud to hear the other person. Apparently on incoming and outgoing calls.

BT Have been to site and confirmed no line fault (we'll see...)

Apparently only affecting some phones and they all appear to be on main 406 unit. Also have DS units but these dont appear to be affected. Customers word though.

Thanks
 
What line are being used on the system BRI, PRI. Also how many channels - can the noise be hear by your customer and the far end caller/called ?
 
I saw white noise on a 2.0 406v1 on DT phones, a very long time ago and it was an IP Office software issue.

Try swapping some users from 406 to a DS unit and visa versa and see if the fault moves.
