● If the source tag name "Type" equals "ITSP" (i.e., SIP message from the ITSP), then use
the value (port number) of the local port on which the incoming message from the proxy
server is received by the device, as the value of the destination tag name "Port". In other
words, the value could either be "6001", "6002", or "6003". This value is then used by the
IP-to-IP Routing table to determine to which IP PBX to send the message. For example, if
the destination tag value is "6001", the device identifies the destination as "PBX-1":
