What happens when VG200 Routers have an ISDN PRI carrying voice traffic?
A. When VG200 Routers have an ISDN PRI carrying voice traffic, by default, DFM generates a Warning alert whenever a phone call uses a B-channel. For every ISDNBCHANNEL, set the Managed State as False in Device Detailed View. They are then listed with the Backup Mode. However, removing the Backup Interface Support Settings is not a workaround since that will cause LMS to report an error whenever any B-channel is not in use.
