[Linphone-developers] Adding half-duplex preemptive operation option to Linphone

[Pedro Sanchez]

Hello,

We'd like to use linphone in an application that requires a half-duplex 
preemptive operation mode to be available. By preemptive I mean that 
active *voice* audio originating from the remote end of the connection 
and detected as such locally will always enforce muting of the local 
linphone client. Local linphone audio can only be delivered to the 
remote end as long as no incoming *voice* audio is detected.

Would anyone be willing to provide me with some guidelines on how modify 
linphone to implement this feature? I'm only interested in the core 
changes, I guess in the media streaming side of things, so that linphone 
in console mode (linphonec) can use it. Supporting this operation from 
the GUI front end is out of scope for me.

Any help would be very much appreciated.

Thanks,
