Hi,

Did you try disabling adaptive jitter buffer ("audio_adaptive_jitt_comp_enabled=0" in the [rtp] section)?

Cheers,
Ghislain

Hi,

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.

This whas already done.

If you want to disable rtcp, set "rtcp_enabled=0" in the [rtp] section
of your .linphonerc file.

Thank you very much for this tip-off. :-) (Not found in

Now, my Linphone doesn't send useless rtcp packets any more. But this doesn't have any effect on the unorthodox metronome of transmitted rtp packets.

As an example, this is a little list of consecutive delta times in transmitted and received rtp packets at the beginning of my last call with Iptel echo. (Linux Mageia 3 on PC):

Packet    Delta(ms)(Tr)    Delta(ms)(Rec)
