[Freeswitch-users] Play music to A leg.

Dear friends, In event socket, I'm originating a call to a number from A leg and till the person answers the call, I would want to play some music to the A leg, till I bridge these A leg and originated call. I don't want to use bridge, in which I could use ringback. So, what is the way to do this?? -- Regards, Nagalenoj H.
