Media flow managed by 2 terminations

Is it possible to manage a same flow by 2 termination (one physical and 
another ephymeral)?


Specifically, I need to manage the packet flows (SAPI 16) in a D-channel 
ISDN. My proposal is to use:

+ A physical termination to manage the overall D-channel. When that 
termination detects a packet flow (SAPI 16/TEI x), it would send a 
notify to the MGC.

+ MGC would create an ephemeral termination to manage that packet flow 
(SAPI 16/TEI x) and the physical termination should continue to manage 
the rest of packet flows (with different TEI) in that D-channel.

Does H.248.1 allow this?
