I have a BCM 4.0 with a straight T1. All has been well until last week when , if you called any number at the site, you would get dial tone back in your ear. You can not do anything with the dial tone you get back. They could make outgoing calls ok over the T1. I tried to disable/enablew the T1, do a warm reset on the BCM. The only way I got it fixed was a power re-cycle. This was last Thursday and now today it is doing the same thing again. Any one ran into this? Thanks.
