 There's a '''session-terminate''' from the recipient. At this point,
 Pidgin looks up the session and deletes it.

 Sending the '''session-accept''' after that seems to be a minor flaw of
 the remote client. Still, the remote side only offers an empty
 '''transport''' entry, which probably means it couldn't find a way to
 connect to you. Maybe its ICE (NAT traversal) isn't set up properly.

 Some questions:
 - Which client does your peer use (also Pidgin?), and what version?
 - is ICE support enabled on the remote client?
 - Is it properly configured to gather its (the router's) public IP address
 (using an STUN server, UPnP enabled in router or IP address entered
 manually?)
 - What happens if the remote side starts the conference? Does the
 '''session-initiate''' contain local and public IP addresses?
