I need a little help on a 406 I am troubleshooting. It has a 30 digital station expansion module, 16 port analog trunk module and the system itself. There are 9 POTS lines also. I am able to conference two trunk lines together, but when I try to transfer one trunk to another, I get this digital static noise that is so bad that the callers cant hear each other at all. I figured that since conferencing takes place in the controller and transferring in the trunk module, replace the trunk module, but that didn't help. Prior to that, the telco was out to check their lines and determined them to be within spec's. Also, it may be related, the phones get fairly bad feed back when the are on speaker phone but only on an outside line. I set the echo cancellation delay to various different setting but it did not make a difference (I think that is what that is what that is suppose to fix). Thanks for your help.
