Not sure I understand what you are saying here.
The MPD/memory module are a pair from a different system I acquired on ebay, they are a version 6.05 factory pair, also a few otehr cards I acquired in that system i swapped out of mine like the T1, 1-ELD, OCD w/modem & dtmf modules. All of these are from a working 6.05 system, so just the remaining cards in my system would need to be upgraded correct? Unforutunately there wasn't a mim in the newly acquired system and thus my problem, that is with the voice paths on the mim shutting down at random unexpected times and can only be restored by rebooting. Also I wouldn't want to upgrade the IVM as there are a few users that have messages archived and the upgrade would lose them I believe. I have an IVM version 3.?? running with sb6.08 at another site without any problems at all for over 10 months.
( we have previously discussed that site, that is 2 128's networked with a T1 (at remote sites) that I intend to upgrade the host end to a 400 version 7.23 and the remote as a 128 version 7.23 sometime real soon. Remember Billy Putnam?

You need to be running 4.00J software on the IVM to work correctly with the SB6 system. This per Telrad. The problem you discribe is one of the listed troubles if you dont upgrade the software. This upgrade will not delete mailboxes or messages it is a upgrade not a reinstall. And you can use the software to upgrade both of the IVM's. Do you have a DPLL clock on the MPD for the T1? Since your into eBay shopping go get the MIM listed on there now it's a 2.6. For correct operation of the system and voicemail you should use the same software (chip) level on like cards. I can supply the upgrade chips and IVM software.
