[Freeswitch-users] cisco spa50xG and music on hold

We have a problem with music on hold on the 504g phones, wonder if anyone has this working. When an inbound call to a 504g is placed on hold, the stream is played towards to cisco504g instead of the calling party who is now on hold. In the Cisco 504g we have the moh server set blank. Also, if we park the call to the 504g, retrieve it, then place it on hold, then the music on hold works. Any one have any thoughts or ideas on this. Darcy Primrose Voice2Net
