[Linphone-users] typical delay (latency) time ?

[Marc-Olivier BERNARD]

Hi there,    
    
I encounter important delay by using VoIP/liphone, about 1s and don't  
understand why.  
  
I'm using linphone between 2 computer (see below for system infos) both  
connected to internet with (A)DSL, with   
  
* ping average time is 120 ms.  
* sound traitement at both ends are quite quick (I did not try with an ALSA  
driver)  
* both machines are directly connected to internet  
* no delay due to firewall (i tried without firewall)  
* codecs G711  
* jitter compensation of 60 ms  
* no proxy  
  
and the delay is around 1s. I don't understand the origin of such a delay ? 
 
What kind of delay do you have ? and do you have any idea how to get it better 
(install ALSA driver for ex.) ? 
  
system infos :

linphone-0.8.0-1
