Asterisk Call Files question

Can each call file contain multiple calls, or do I have to create a separate .call for every one? Can I put the two calls below in the same .call:

Channel: SIP/trunk1/16631126116
CallerID: Blahblahblah <2981002781>
MaxRetries: 0
RetryTime: 0
WaitTime: 30
Context: dialer
Extension: 400
Priority: 1

Channel: SIP/trunk1/17221152112
CallerID: Blahblahblah <2981002781>
MaxRetries: 0
RetryTime: 0
WaitTime: 30
Context: dialer
Extension: 400
Priority: 1

Call files u mean? How you are creating extension through GUI or terminal.If GUI may be macro calling happens.
