[Freeswitch-users] Suppressing music on hold in conferences

From the default dialplan:

<condition field="destination_number" expression="^9(888|1616|3232)$"> <action application="export" data="hold_music=silence"/> I have just written a similar entry for another conference that I frequently call. If I call the conference from FreeSWITCH via a SIP phone, then place the call on hold, the hold music is suppressed as intended. However, if I call the conference from PortAudio, the above dial-plan logic doesn't have the desired effect - I still get music on hold. The info application shows that the variable is being exported, however. This is under revision 13266. Is this a bug, or is there additional dialplan logic that I need to supply? If it's a bug, could someone add it to the bug list? Thanks.
