[Linphone-users] video troubles: sip number to test video?

[Liviu Andronic]

Dear all
I'm currently playing with linphone 3.4.1 on my two Xubuntu 64-bit systems  
(10.04 and 10.10) using a SIP account from @iptel.org (and previously with  
@sip.linphone.org and even @ekiga.net). Audio seems quite robust; I've  
tested using address@hidden and address@hidden, and by calling the other  
Xubuntu system on the same internet connection.

However I get very bad video performance, and I cannot pin down the issue  
to linphone/codec, my internet connection or proxy performance. When I  
call myself on the other Xubuntu system, the video is very jerky and  
pixelized, and my network monitor shows an average download and upload  
speed of 10 kbytes/s. Using Skype to call my friends I get consistent  
down/up speeds of 70kbytes/s and very acceptable video quality. As far as  
the linphone prefs go, I use h264 on one box and mp4v-es on the other,  
with 256kbit/s down limit and 128kbit/s up limit (my internet connection  
can easily do down speeds of 400-500kbit/s when the server permits it).

Any ideas on what's wrong with the setup? Can somebody suggest a SIP  
number to test the video quality? I've tried address@hidden [1], but it  
looks broken. And an internet search didn't get me anywhere. Thank you
Liviu
