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

[Simon Morlat]

Hi,

This is already implemented. See the "Echo limiter" description on
http://www.linphone.org/eng/documentation/dev/tuning-linphone.html

You may need to set the el_force parameter to a greater value (100000) 
to cut voice entirely.
