Place a call to it and if the phone reports BUSY, asterisk will return  
BUSY.

Another way is to use the GROUPCOUNT set of functions, to keep a state  
in Asterisk or to use the embedded call counter in the SIP channel  
driver, that is reported in the SIPPEER function.

As often is the case, there are many ways to solve an issue in Asterisk.
