I have a 2600 router with ISDN PRI and 1 serial Interface. Approx. 150 Clients are connecting to the PRI. In case of a serial link failure there should be ISDN-Backup (2 B-Channels) over the same PRI the Clients are connecting to.
Is there a possibility to configure a rotary-group but give the 2 B-Channels (needed for backing up the serial line) priority over the others? Like if all 30 channels are in use by some clients to drop 2 channels and use them for the backup.
With dialer-profiles I could reserve 2 channels for the backup but I want to avoid configuring 150 dialer-interfaces.
