With Voxalot the call is first established with RTP media streams through Voxalot, then if certain conditions are met INVITEs are sent to each end in an attempt to shorten the audio path. This is the first INVITE for the sender, but second INVITE for recipient.

In both samples you sent me, the recipient is not redirecting RTP to sender, the result is that the recipient's RTP stream continues to pass through Voxalot on it's way to the sender.

Both samples contain RTP pacekets in both directions, and yet no sound is heard in one direction when using X-Lite. Is there a codec issue? I see "Media Attribute (a): rtpmap:0 PCMU/8000" in Session Description from ekiga, but not from X-Lite.
