[Freeswitch-users] FS as a Class 5 switch

hi everybody, i'm interested to know if anyone employed FS as a local exchange switch. i'm confident FS can handle several calls using RTP by-pass mode. however, i'm more concerned on handling the large dialplan with hundreds (or even a few thousand) exchange prefixes nationwide during call setup. i'd be glad to hear experiences and suggestions esp on the hardware dimensioning. we're talking a small exchange up to about 1,100 lines only, mostly linked to the main exchange via MFC-R2. tks, nandy
