In-Band Bytestreams Session: NOTHING SENT & RECEIVED (no <open>, <data> & <close> message)
Terminate: NOTHING SENT & RECEIVED
Remarks:
Chat works between client A & client B and other services work
File transfer works with firewall deactivated on both clients in order to use direct file transfer (in p2p)
File transfer works with 2 Spark clients with firewall activated on both clients (with “IBB only” option activated in Spark admin interface, maybe the XEP-0047 In-Band Bytestreams extension is used in place of the XEP-0261 Jingle In-Band Bytestreams Transport Method extension)
