Need to know what Version IOS for AS5800 and What Version MICA

We are a wholesale dialup provider that interconnects directly to an ILEC using CAS MF (Multi Frequency) T1 Trunks utilizing AS5800 NAS's. Currently we're running version IOS (tm) 5800 Software (C5800-P4-M), Version 12.3(10), RELEASE SOFTWARE (fc3) and MICA Code mica-modem-pw. Mica Portware

My question is, What IOS should we be running and should we be upgrading to MICA code We've tried to upgrade to but I didnt notice any signifigant change in performance and in some cases, client CPE's seemed to have a harder time connecting to our modems after the upgrade.

Also, There used to be a Modem Interopabilty list for Cisco AS5800, I can't seem to find that Document, is it online or can someone send me a copy?

not sure if this is the document you are looking for:

Cisco AS5800 Series Universal Gateways

Compatibility Matrix for Cisco MICA 6-Port and 12-Port Module Portware for Cisco AS5x00, Cisco 36x0, and Cisco 37x0

As for the code problems, you might want to check the caveats in the release notes:

Re: Need to know what Version IOS for AS5800 and What Version MI

For a list of modems tested with Cisco MICA portware, refer to the Modem Interoperability List for V.34 and V.90 Modems document on

Basically, I'm looking for a known list of Client CPE modems that have been tested with Cisco AS5800's.
