[Asterisk-Users] No zap/sip/etc options?

[Matt]

Does anyone know what would cause a 1.2.6 or 1.2.7 asterisk system to
do the following?

After inserting a zaptel card the system starts up and when I log into
the asterisk CLI I can't do a show sip, show zap, or show iax2 
commands.. they just don't exist.   Likewise, a help shows no such
commands.

Removing the card causes the system to go back to normal.
