I am losing access to the PBX that my small business has been utilizing, and I am considering setting up a simple, cheap VoIP system. I have some older hardware and a friend who is a linux whiz.
My question is: is there a cheap easy way to create a redundant, analogue terminal (phone/answering machine) that will automatically hook into the PSTN should my VoIP server crash? We can’t afford to lose any calls, since that is how our clients place their orders.
I apologize if this question is answered in the FAQ. I was unable to find any reference to it.
Thanks in advance for any help
