Hi Maud

Here is the response from development:

We don't support this because when in BroadSoft and Sylantro environments, the servers act as 3pcc's so the phone doesn't need to do anything for the system to get MOH (i.e., we don't need 7155 in these environments.

Pat

Hello,

I've posted you so many mails about a feature of Hold key on Polycom soundpoint IP .

Will Polycom provide Hold key configuration to place on hold a caller with music when music is provided by a dedicated server

I do hope you'll answer me. if Polycom is not able to provide this feature i'll look for an other Ip phones proviver. 

Regards

Harry

   In this flow, Bob places Alice on hold with music. 
This is performed
   by Bob acting as a 3pcc (third party call
controller) [17] to INVITE
   a Music Server into the session, which sends RTP music to Alice.  Bob
   picks the call up from hold by sending a BYE to the music server and
   taking Alice off of hold.

   Note that if Alice responds to the INVITE with hold SDP with hold SDP
   in the 200 OK, this call flow will not work properly.

   Note also that Alice will receive RTP packets from two different IP
   addresses during this call flow.  Alice could refuse the music by
   sending a re-INVITE changing the session to a=inactive.
