UNIStim Question 1

[cndr99]

So here's a question: what is in the UNISTim firmware? Is it possible to upload it into any other brand of IP at all?

I think it's proprietary to Nortel system/sets only.

Agree with curlycord. Not only is Unistim proprietary to Nortel IP sets, it seems every model IP phone has its own firmware. I'm certain another make of IP phone would be bricked if flashed with Nortel IP firmware.

Nop UNISTim is Nortel oriented protocol. Avaya adopted in Nortel rebranded sets but it is still a Nortel proprietary protocol.

I get that - but software is software...what I was wondering was how different could the the circuitry, memory or processors be on the average IP phone - are there any generics that might possibly take any kind of firmware?

I have used a I2004 and I2002 on my Asterisk Server as Unistim.

Depending on a processor used on the IP phone you select, you maybe able to execute the firmware - however that doesn't mean it will work. Every phone has different I/Cs and drivers it needs to talk to. The chance of any driver or I/C actually understanding what the Nortel firmware is telling it to do is pretty much nil to none. Nortel made everything themselves, so it's their I/Cs (or mostly their I/Cs), their boards, their drivers, their everything. The chance of other manufactures using the same commands to drive their I/Cs and "stuff" is very unlikely. I can't see how this would ever work.

Thanks TheMitelGuy... that makes sense - I guess if one had a reference for the hardware, one could write their own firmware - sadly my knowledge of assembler was last used in about 1982 to pass a computer programming course! HAHAHA.

Obviously, its not commercially feasible or even advisable to write new firmware for every piece of hardware that comes up - but as a hobbyist, it interests me how the guts of these things work. It would be interesting if there were a generic firmware "editor" that could be used to create custom firmware for obsolete or equipment that can't be replaced with anything currently available...

Thanks for the thoughts everyone!
