Unable to connect free vers to POTS lines

i have downloaded and installed the free vers of the switchvox software…the system recognizes my digium analog board with two of the four slots activated. the call group is configured and is using kewlstart signaling. when i plug in known working pots lines to the digium board i can not place any outbound calls thru those lines nor recieve any call inbound on those lines. any help would be appreciated.

what does your zapata config look like? What is the output of zap show channels from CLI?
