Audio call with Jitsi over xmpp?

[Hong Xu]

Hi,

I tried to make an audio call with Jitsi over an xmpp account on the 
same host. The two clients are both within my home network. However, as 
long as the call was picked, Jitsi prompted "Error: Could not establish 
conection (ICE failed and no relay found)" and the call ended. On the 
pidgin side, there is no prompt: just the audio chat dialog disappeared. 
There is no command line output if I launch pidgin from command line. 
The results are the same no matter which way I do (either call from 
Jitsi to pidgin or pidgin to Jitsi). Do you have any suggestions?
