Question on application of tones on ephemeral terminations

Hi all,
 
I know that a scenario where the ring-back tone is applied from the
remote side emulating TDM is quite common. My question is about the
correct mode of the remote ephemeral termination.
 
According to H.248.1 (par 7.1.7) "Signals and Events are not affected by
mode", that is, the mode affects only the media. However, when a tone
(Signal) is applied on an ephemeral termination, the tone is converted
to media (RTP); therefore, if a Signal (ring-back tone) is applied to
the remote ephemeral termination which is in "inactive" mode, what
should be the behaviour of the MG? Should the RTP packets with the tone
be sent outside the Context or not?
 
Thanks,
 
MMAR
