I know this is a stretch.
Does anyone know where to acquire software to program a system25? If not...does anyone have an old Integrated Solutions (IS3) Unix PC with the software in working order? For purchase.

Thanks.

Forget this thing and get something else.

They are as long gone as the HORIZON.

Even the expert techs I know would tell you to just go ahead and upgrade to something else.

Did this have Voice Mail and Call Accounting?

The greatest phone system ever produced. If you provide your email I can send you a zipped DOS version.

Except for the fans and dust filter that had to be checked on a regular basis..I agree with GKAR.
The Horizon in its day was alot better than the
old wire spring relay switches we had to deal with...trust me, I'm glad its log gone too....
however the 25 is a different issue...with Legend
parts so cheap now..I agree it time to move on...
but they were the best thing going for a long time.

I agree 100%. Let the Sys 25 go already, although I liked the system. They are a not for profit that is trying to get another 6 mos out of 2 sites w/ Sys 25s.
After this I will stop enabling them

I have 4 customers with 25's and I'm telling them
this is the year I stop the 25 tech support. I do have spare parts, but I prefer the Legend.
Ebay is loaded with used Legends w/ sets cheap.
You do know the merlin analog sets will migrate
to the legend...so its just the CPU you have to
replace.

Had many customers with sys 25's,still have various parts in boxes. Last customers that we upgraded,a trade in on phones but not carriers. 20 yrs from now,this system might be collected like old 1a2's are now. Just don't have space to find out.

My biggest customer had 5 system 25's, now down to 2 and by the end of next week it will be 1.
