Hi listeners,
The draft says
The special duration value of 0 is reserved to indicate |
that the event lasts "forever", i.e., is a state and is |
considered to be effective until updated. For robustness, |
the sender SHOULD still retransmit the named event |
periodically.
1) From an implementation perspective, if we receive Event packet with '0'
duration, is this event supposed to be played out infinitely until either
the 'End-bit' or a new timestamp ? What are consequences if the 'End-bit'
packets (even if transmitted multiple times) get lost and the other side is
then in a mode of DTX (discontinuous transmission), will this mean the tone
gets elongated beyond actual length ?
2) Also what does RFC2833 say about the expected behaviour when duration is
0 for tone packet (the other kind of rfc2833 packet) ?
Thanks,
Raghavendra
