In 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 .
1) Make interdomain voice call

2) Send file between clients registered in different IMS domains
For chat and send file service Boghe client is using MSRP, so for file transfer SDP description with MSRP end points definition have to be exchanged
