摘要
The method involves establishing call connection between first participant (MS1) in a telephone network (CS) and second participant (MS2) in an IP-based network (IMS) with reference to the signaling protocols (BICC,SIP) used in the telephone and IP-based networks. The call messages in the first signaling protocol (BICC) are converted into call message in the second signaling protocol (SIP) using specified codes. The specified codes are sent and used during the video telephone connection. The data link in the telephone network uses H.245 signaling protocol for data exchange. An independent claim is included for the data network.
