Set waiting tone for asterisk agi function processing

Question

I am using asterisk with normal PHP AGI following this link the problem is that my PHP AGI takes 5 seconds to execute .I just want to set some waiting tone for the user to wait until the AGI is been processing. On the same link I found something:

set music: Enable/Disable Music on hold generator, example "SET MUSIC ON default

but I don't know exactly how to use I mean what would be the exact syntax and where do I put it.

I have tried adding

same => n,Set(CHANNEL(musicclass)=default)

but it didn't work.

Answer 1

If you use phpagi, you have do something like this

$agi->set_music(true,"myholdclass")
...
$agi->set_music(false)

http://phpagi.sourceforge.net/phpagi2/docs/phpAGI/AGI.html#methodset_music

Sure you need first describe myholdclass in /etc/asterisk/musiconhold.conf
