Have any of you who are running BC12-SP08, run into trouble with the older digital telephone instruments, particualry the DBC 661 & DBC 662? We recently upgraded our system from SP07 to SP08 and notice some troubles.
The problem is that extensions equipped with DBC 661 & 662 have a large gain increase to the point of distortion. This is since the upgrade to SP08. Any ideas why, or how this may be adjusted? The attenuaion settings do not seem to affect this issue.
