Re: [GnomeMeeting-devel-list] selecting output device - bug?

[Damien Sandras <dsandras seconix com>]

Hello,


I have an USB headset, and I do not have your problem.

To make sure that the problem is not related to NAT (which I'm 99% sure
it is), can't you try calling another GM instance on another computer on
the LAN?
