a call or something like this, telling me that 15 of 30 channels are busy.
How can I do this?

/usr/sbin/asterisk -rx "core show channels"|grep Zap will show you how many
Zap channels are open at any moment.  You can grep for SIP, Zap or DAHDI (or
IAX) depending on your release/technology. 

To do this as you specified, you would record a message (say busy15.gsm) and
set up a call file to call yourself and play the busy15 message.  I used to
have my Asterisk call me whenever it restarted this way.

if I use the asterisk -rx cmd, this is the result:
>>Zap/63-1             (None)               Up      Bridged Call(SIP/xxx)

>>It won't show how many zap channels are busy ..... I need to count the
busy channels, and with the count results, dial to an exten and tell how
many channels are busy ;

/usr/sbin/asterisk -rx "core show channels"|grep Zap|wc

Will give you just the number of channels in use of type Zap.  It isn't too
hard to evaluate and act from that.  Just don't have my shell scripting hat
on today.
