Hi.
I am working with linphone library in ubuntu x64. the problem is that when initiating a conference call, the local and remote parties can't hear any sound for a while. After a few seconds (~ 10-20 sec), conference call works properly. It is worth noting that everything is ok when the remote party accepts the call in auto answer mode. I have this problem when the remote accepts the conference with some delay.
I'm really sick of the situation, any response is appreciated.
