So internally the vmail ports are dialing the Hunt Group number for the att group ....
Boy thats a good one . Something in the NBX is telling it to dial a number . There are 2 places to turn off osn but I think if there is a msg it will continue to try .
You can enable cfg logging for the vmail ports , but not sure if it will tell you .
I would be on at least 6.0.63 code but that should not make a difference ....
V3K on 6.0.49 code .
OSN was enabled but is now off .
Any Main Att Mboxes that may have a msg or someone able to leave msg's in that is using OSN ?
