But that's not a vaild comparison. Cisco's IOS is virtually the same no matter what router it runs on. A more valid comparison would be with the AS5200. I'm not aware of the status of that WRT V.92, however. Is Cisco supplying updates free, if at all? No, Cisco do not have plan to support V92 on as5200 (and on as5100 too)...

There are some good reasons (not sure that you'd call them "technical") why we won't support V.92/V.44 on the 5200.
For Microcom digital modems, that code has been end-of-engineering for quite a long time. The DSP code (CSMv1) belongs to Conexant who has stopped developing it. The CP code belongs to Microcom who got acquired by Compaq who did I'm not sure what with them. So there's no way they're going to get V.92/V.44.
For MICA on the 5200 ... we COULD theoretically support V.92/V.44 on them ... but in order to support these protocols, we need to enhance IOS. Part of this is quasi-cosmetic stuff like adding different speeds and modulation types in the MIBs and "show" output formats and suchlike. But part of this - notably for the Modem On Hold feature - will require changes to our modem state machines.
Now, our IOS support for V.92/V.44, as with all new features, is going into 12.2T train. The problem for the 5200 is that it won't run 12.2T, or even 12.2 mainline ... its end-of-the-line is 12.1/12.1AA. This is because IOS keeps getting bigger and bigger while the 5200 can hold only 16MB of RAM.
If you have MICA boards in your 5200, you could pull out the HMMs and put them into 5300 carrier cards and get V.92/V.44 that way (I don't know how worth-it this would be) ... and you would still have a pretty decent ISDN/frame relay router left over.
