[Libav-user] Marker Bit In RTP for Voice Samples for codec like AMR and G729

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??
