Ok clarification. I want a hardware EPABX system and not a software solution
I can't keep a PC on 24x7 for saving on PABX system. That will cost me more in terms of electricity bills
Nor is there enough place for a PC in that area. I am replacing an existing 5 year PABX which is placed in a small cupboard.
Q: What is the most important thing to know about installing trixbox?
A: During the install process, ALL hard drives connected to your system will be formatted and all data will be lost. This will even apply to any external USB drives.
So it needs a near-dedicated machine! Machine will cost me more than PABX system
