[daveybc]

Running a BCM50 Ver. 3.0 with some 1120e and 1140e IP tel. sets at a remote location. The BCM is reporting the following errors:

Customer has VPN set up, Port 7000 is open. Sets work but customer is complaining about QOS.

There could be a number of errors such as bandwidth at the remote end, voice priorty and if QOS is properly enabled.

All the best

If it's working, then leave it alone!.

I definitely think the QOS is not properly enabled as other areas have been tested and excluded. Here are some questions I have relating to QOS:

Is it setup by default?
What priorities are enabled?
what are the implications of running this with qos over a network where it is not being used?

Any other info. about BCM50 QOS would be appreciated.
