[Asterisk-Users] Intercept HOLD of Snom phones

[Magnus Jungsbluth]

Hi,

I'm running the 1.0 release of Asterisk an it is working nicely with our 
snom 105 phones. Hold puts the caller on hold, attended / unattended 
Transfer works directly with the snom buttons ...
I have one question though: what does the snom exactly do to tell the * 
to put the call on hold (can I intercept this somewhere)?
 
I would like to decide using the callerid which music on hold is tobe 
played: That is: play "free" music to calls from the outside but play 
copyrighted music if I put an internal call on hold (i.e. a co-worker). 
Is this possible ?

regards,
