asterisk users - Oct 2003 - no dial out

I can not dial out

Error


1242952640]: File channel.c, Line 1642 (ast_request): No channel type re
gistered for ''
NOTICE[1242952640]: File app_dial.c, Line 516 (dial_exec): Unable to
create channel 



I believe this to be the device in phone.conf

Am I heading in the right dirrection ???
