What OS version are you using on your Max? The customers may need to
upgrade their firmware code in their modems. We ran into this problem
several months ago with some Compaq modems. They wouldn't connect until
the firmware in them was upgraded (especially K56Flex modems with older
firmware versions). See http://support.talstar.com/56k.html for some info
and links to the manufacturer pages... (the info is useful even if the
modems are V.34)
Right now, the only modems that we know of that refuses to connect to us
are the IBM Aptiva MWave modems.
Yesterday, Ascend released OS version 6.1.0 which includes V.90 version
2.084. Though the V.90 part may not be relevant to the customers that are
having the problems, the OS upgrade in general may take care of some
problems.
I haven't upgraded from 6.0.4 to 6.1.0 yet, but will probably do so in a
couple days.
