[Asterisk-Users] polycom soundpoint 300 sip phone and hold music

[Derrick Stensrud]

I have an extension setup in my extensions.conf for hold music.  ext. 600.

If I pick up a phone (polycom soundpoint 300 sip) and dial extension 600 
I hear the hold music playing.  If I call another extension and pick it 
up and put the call on hold with the hold button on the phone I hear 
nothing at all.  Does anyone have any experience with these phones and 
getting the hold button to work?
