I have an Opt 81 and we have it interfaced with Cisco VOIP. The system has been working great, then all of a sudden we can't make calls from Nortel to Cisco, all calls go to the Operator.I have found that the only way to get around this problem is to change the TGAR to 8 on the Nortel ext. then the call will go through.Anybody have any ideas what has changed to make this happen.
