[Freeswitch-users] Background music in conversation

Hi, The scnario required is as follows: A calls B using FS, and a music should be played in the background while they are talking. I have searched whole wiki and fs docs and mod_dptools but unable to find a pointer so far. Even in asterisk, this has no plain solutions, other than to bring both the parties in a meetme room and starting moh for a third party on local/ channel. Anyone help me out or any links ? Best Regards, ashutosh
