[Linphone-users]connection with linphone only in one direction

[Dirk Gerdes]

Hello everybody ! 
We are students of the Hochschule Niederrhein, Krefeld in Germany 
We are working on a project considering Voice over IP. 
 
Trying to use Linphone we got the following problem: 
We only get a connection in one direction. That means: 
If you talk on one side you can be heard on the other side. but if you talk on 
theother 
side, on the first side you don't hear anything. 
It seems to be random, which side can be heard and which not. 
 
We are running Linphone under Debian  
using Kernel 2.4.17 
in a local Network. 
We tried several versions of linphone(0.9, 0.9.1, 0.10) regarding this problem 
with 
each of them. 
 
 
We would be very happy, if anyone had an idea.
