Determine Max Simultaneous Calls on 3825

[nagel]

Is there a way/command to determine (from the router)the maximum number of smultaneous calls that have run through a 3825 Voice Gateway? IOS is currently 12.4(19). Thanks in advance.

Do you have CM ? If so, it can produce many statistics of this type.

Else, you can monitor the ISDN MIB with any snmp tools and it will produce a graph of channel usage over time.

Hope this helps, please rate post if it does!

We have CM but I would rather determine from the router side as I am on Network Side of house and I don't want to interfere with phone guys. The ISDN MIB might work for me - do you have any additional info on it?

ISDN MIB:

Watch out that if you're using MGCP, I'm not sure if that would work.

Hope this helps, please rate post if it does!

It doesn't appear that ISDN MIB RFC 2127 is available for the 3825 platform. Do you know for a fact that it is. It all appears that it is only available for BRI connect. We currently utilize PRI.

Yes it is, you worry not. Now checking better I think the MIB is this one:
