I would think this might be a common question / problem in here.
I had a customer call yesterday with a Siemens Hicom 150 System (OfficePoint).
The office manager had defaulted the system and it went back to scratch, including German Language.
I wouldn't normally maintain a Siemens System, but our compant was the only company she contacted that offered to help her out. (Past vendor out of business) Soooooo..... the typical questions:
How do I find manuals and any information/software on programming the system?
I did find some limited information on programming the sets:
https://wwwhephy.oeaw.ac.at/telefon1/en/h150/mem/30/ba/01/index.htm https://wwwhephy.oeaw.ac.at/telefon/index.htm They have about 10 Optiset E telephones and they have voice mail as well.
Any information would be a huge help to them and to me.
Thanks!
