[Freeswitch-users] Using FS with Asterisk as a PBX

I'm new to FS. I am trying to get started with implementing a phone system to manage 12+ small companies. I'd planned to use Asterisk, but I've come to understand the problems with it on a larger scale. My question is will I avoid potential problems by using FS to manage 12 Asterisk PBXs? OR is it advantageous to use FS's PBX abilities? Thanks for your opinions and expertise.
