Help with zap


I have finally managed to install asterisk.

I installed zaptel and the little green light is on on my TDM01B.

When I do ztcfg -vv I get:

Channel map:
Channel 01: FXS Kewlstart (Default) (Slaves: 01)
1 channels configured.

Problem is, (and I think it is a problem), when I type ‘zap show channels’ I just get:

redhat*CLI> zap show channels
Chan Extension Context Language MusicOnHold
pseudo from-ntl

When I call the PSTN line I get nothing on the CLI Screen.

In extensions.conf I have

exten => s,1,answer()
exten => s,2,hangup()

But this isn’t working, the phone just rings and rings.

Where should I begin to look to resolve this?
