在php agi中获取DNID

Question

How to get DNID (the number that end user dialled to get to my asterisk server) to my php agi script? I tried

$agi->get_fullvariable("DNID"); 
$agi->get_fullvariable("${DNID}");
$agi->get_fullvariable("${CALLERID(dnid)}");
$agi->get_fullvariable("{CALLERID(dnid)}");

but i did not get a value. Also can anyone give the proper syntax/method to read an asterisk variable from php agi?

Answer 1

I figured out a method. Asterisk passes some data to the agi script, which can be seen by running

agi set debug on

in asterisk cli. If you are using the phpagi library, then

$agi->request['agi_dnid'] 

will hold the dialled number or the number which the caller dialled to get to our asterisk server.
