\n\tIn our labs we have two IMS domains installed, one is OpenIMScore based, another is using Kamailio IMS components. We are trying to make interdomain sessions to test basic reachability. We provide call flows captured for interdomain call session establishment and the call flow established during sending of a file .<\/p>\n
