[Linphone-users] Linphone sends 2voice packets at the same time every 40 ms.

[LiXingCai]

Hi, Linphone authors,

I am a new comer. I am using the linphone as my Sip client to make a call. And 
it looks work well. With using wireshark to check the time stamp for the g.711 
ulaw data, I found that every 40 ms, linphone sends 2 voice packets. While 
other sip phone such as X-lite, always send one packet every 20ms.

I believe the 2 packets sending every 40ms should be a intended setting by the 
author. But this setting isnot my expecting result.

Could you please tell me how to change this setting , if it is, to make sure 
the linphone can send a voice packet every 20ms?

Best regards,

Bob Li
