Hi, My name is Francisco from México. Here, in my work we have a very very old panasonic PBX(12 years old). We are growing and we need to increase our external lines(from 3 to 4) and our internal lines(from 6 to 10). Besides we need voice mail and voice menu too. We asked for a quote to our panasonic dealer. The whole thing cost about 4,500 dollars. My boss just saw a thing called FreeSwitch this morning looking for options in Google. He asked my to investigate what this thing called FreeSwitch is and if we could save some money using it instead of the panasonic solution. So, here I am. I have some experience as linux sysadmin(we have 1 oracle linux server and 1 linux print server) nevertheless I don´t have any idea where and how to start this evaluation? Please Would you give us a clue where to see If FreeSwitch could work for us? Thanks for your kind help.
