You are requesting the hard coded channel (time slot) 1 - are you sure it
is free? What does "zap show channel 1" say?

Like someone else said - have you tried to define a group and call 
"Zap/g1/......"? The message above means that asterisk does not consider 
the channel Zap/1 to be available for one reason or another.
