I want to know the significance of Marker Bit in RTP for Voice packets and is here any RFC which tell that.

I know that the for the Video packets marker bit means last packet for the same image and hence, its the last packet with PTS time-stamp corresponding to image but for the Voice Packets for a codec say AMR-NB or G711 alaw or G729, the Marker Bit is usually false in each of the RTP packet.

So, do the meaning of Marker bit changes in this case of RTP packets??
