[Asterisk-Users] Dial Command

[Andrew Elchuk]

I'm trying to use the dial command to initiate a call to number 9661443 
with an X100P card set up on channel 1 with the following in my 
extensions.conf:
    exten => 1,1,Dial(Zap/1/9661443,15)
Then when that command executes in the asterisk daemon I get the following:
    app_dial.c:688 dial_exec Unable to create channel of type 'Zap'
Can anyone tell me what might be wrong?  Thanks.
