[Freeswitch-dev] How is MOH implemented in Freeswitch

    Hi,         It seems Freeswitch implements MOH (music on hold) feature using sofia module.         Reference: http://wiki.freeswitch.org/wiki/Music_on_Hold       Can someone explain (or point me to some design/feature document etc of freeswitch) how it has been implemented?     Regards,     Sushil Kumar
