Hi, my company has an old OfficeServ 7200 system that is currently using ISDN channels and I wanted to start using it with VoIP now that we have a leased line. Originally I thought this should be a simple matter after googling to see what the various modules in the system cabinet were for and finding that the MGI-16 card appeared to allow using SIP trunks
. Some months later I realise I should have just bought some new VoIP handsets and re-cabled the office, but I'm now committed to this course of action and determined to see it though
The first problem I found is that we would need licenses to use the SIP features of our MGI card, and apparently the licensing is discontinued now? Eventually I discovered that the final firmware (v5.0.3 I believe?) will unlock everything. However, our system had the older MCP controller, which it turns out can't run the later firmwares... long story short we ended up buying a used system off eBay with an MP20 and OAS card to use instead (which I think is currently running v4.75, based on what's written on the SD card).
My current problem is trying to reset the admin password (for OSDM) on the new MP20-based system that we bought, since the factory-reset button doesn't appear to do that!? I have found some instructions on how to do this via a handset and am just waiting for an RJ11 to RJ45 cable so that I can try it.
However, since we're happy to just reconfigure everything on a fresh v5.03 system, would that reset the admin password anyway? I mean is there a way we can just overwrite the SD card with a clean copy of the v5.03 software and it will all revert to default settings? Or do I still have to go through some sort of upgrade process from v4.75? I assume I can't upgrade all the way from v4.14 keeping our existing settings as I already tried the SD card from the MCP in the MP20 and it didn't boot up?
In any case, I can't seem to find the v5.03 firmware anywhere. Might somebody here be able to supply it?
Any help/guidance appreciated!
