You can disable adaptive rate control by setting "adaptive_rate_control=0" in the [net] section of your .linphonerc file. You can also enable/disable it in the codecs tab of the preferences. If you want to disable rtcp, set "rtcp_enabled=0" in the [rtp] section of your .linphonerc file.

I previously complained about RTP paquets which intervals constantly change at the transmitting side. Yes, instead of constant 20 ms (± epsilon), wireshark shows discret values 0 ms, 10 ms, 20 ms, 30 ms, 40 ms, 50 ms (± epsilon) intervals, with a noticeable periodicity, no matter the remote side is Linphone, another softphone or my VoIP provider. This periodicity makes me thinking it looks like a relaxation phenomenon, something like a bad feedback loop effect. Is relaxation the right word in english ? Perhaps "pumping" is a better word ? In any way, not any softphones send RTCP packets and my VoIP provider doesn't, so I think the "Adaptive bitrate control" mediatreamer2's feature cannot work usefully when I have a call with a PSTN subscriber.

How could I disable this feature ? Only a developer, that unfortunatly I am not, could say what to change in what file(s) before re-compiling linphone 3.6.0 or 3.6.1. Many thanks in advance.
