To install asterisk, including Dahdi-linux and Dahdi-tools on CentOS 6 and configure it for use with an Atcom AX2G4A card. The driver may also need to be installed.
I have installed CentOS and downloaded the zips from the Atcom website (apparently the Atcom version of Asterisk must be used).
It should also be configured for the SMS sending/receiving as detailed in the instructions.
