disable load balancing on dual PRIs - 3640 with MICA modems for dial out
We have a custom application that connects through reverse telnet to a Cisco 3640 that has 2 NM-24DM modules and 2 PRIs connected to it. Currently all outgoing calls are getting load balanced over the two PRIs. I need to change that so that all calls go over the first PRI and when all channels are used up, it starts using the second PRI. Seems like a simple enough thing to do but I can't figure out how to.
Here is my config

If I understand the question I think that isdn bchan-number-order is the command you are interested in. I think it detaults to round-robin, sounds like you want ascending (that is isdn bchan-number-order ascending). It is an interface subcommand.
