callref Indicates the call reference number in hexadecimal. The field value indicates the number of
calls made from the router (outgoing calls) or the network (incoming calls). Note that the
originator of the SETUP message sets the high-order bit of the call reference number to 0.
The destination of the connection sets the high-order bit to 1 in subsequent call control

becomes callref = 0x84 in the response.
