UCMA Send File & File Transfer Sample

Question

There are no samples using for UCMA to send file from applicationendpoint to userendpoint or vice versa.

I've tried below sample but it didn't work. See code and error:

        if (e.State == MediaFlowState.Active)
        {
            byte[] fileBytes = null;
            using (FileStream fs = File.OpenRead(_fileToSend))
            {
                fileBytes = new byte[fs.Length];
                fs.Read(fileBytes, 0, fileBytes.Length);
            }

            ContentType ct = new ContentType("text/x-msmsgsinvite");
            ct.CharSet = "UTF-8";
            StringBuilder sb = new StringBuilder();
            sb.Append("Application-Name: File Transfer\r\n");
            sb.Append("Application-GUID: {5D3E02AB-6190-11d3-BBBB-00C04F795683}\r\n");
            sb.Append("Invitation-Command: INVITE\r\n");
            sb.Append("Invitation-Cookie: 33267\r\n");
            sb.Append("Application-File: Readme.txt\r\n");
            sb.Append("Application-FileSize: " + fileBytes.Length.ToString() + "\r\n");
            sb.Append("Connectivity: N\r\n\r\n");
            string s = sb.ToString();
            byte[] bytes1 = Encoding.UTF8.GetBytes(s);

            try
            {
                _instantMessagingFlow.BeginSendInstantMessage(ct, bytes1, result1 =>
                {
                    _instantMessagingFlow.EndSendInstantMessage(result1);
                }, null);

                WriteLog.AddLine("File sent to: " + _coachSipAddress + " from: " + _userSipAddress + " the file: " + _fileToSend);
            }
            catch (Exception ex)
            {
                WriteLog.AddLine("File couldn't sent " + ex.StackTrace);
            }
        }

Can anybody help or give any sample for sending file in UCMA for file transfer?

It looks like the invitation isn't being accepted, can you confirm that you are hitting the callback for Flow.BeginSendInstantMessage()? – Smitt

I accepted the invitation but receive this error. – Airbrush

@kdrlzmlr I'm also trying to send a file with UCMA. Did you manage to solve this? – Packard

@meir Yes I did. Follow the instructions at this site. ocsgcf.blogspot.co.uk – Airbrush
