asterisk users - May 2005 - no music on hold

Hello,

I am having problems with music on hold on grandstream phones.
When I press Hold button on grandstream phone this is the debug of sip.
But nothing happens, no music.
Is it problem of asterisk or grandstream budget phone?

Do you have mpg123 installed?
Do you have any mp3's (CBR preferably) in your moh directory?
Have you defined any moh classes in musiconhold.conf?
