[Asterisk-Users] Any 24 (or 30) way FXS PCI cards?

[Max W Blackmer Jr]

Voip supply has a few 24 port gateways that are FXS based. The biggest
one for FXO is 10 ports. They are not cheap the both cost about $2000
USD.  a Channel bank with a T1 card will cost you about the same at
least with a FXS ports.  

FXO costs more usually because that is typically the Office station side
that has much lager power requirements. Where FXS is the phone/customer
side of the Communications. .
