• 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":
