[SIPForum-discussion] Early media...Use.

[???]

early media is usually being used in case of "multimedia ring back tone".
When we place a call to somebody, we usually hear ring back tone.."ring.....ring.....".
But the ring back tone is customized. Such as music or recorded voice something like that before called party answers the call.
