[Asterisk-Users] More than 20 FXS

[Nahuel Alejandro Ramos]

Hi everyone,
  Could someone tell me if I could make a Asterisk PBX + Digium
hardware with more than 20 FXS? If I have a 5 PCI PC, I could only
plug 5 TDM40B (4-port FXS) maximun. Is there a solution, a hardware in
Digium or something that let me have a PBX with about 50 or 100 FXS
and internal phone using a Asterisk PC.
  Thank you very much...

         Nahuel Ramos.
