Internet Protocol (H.450) 140
SBX IP 320 Features & Operation Guide
Conditions
• If both transferred Stations and transferred-to Stations are located in the same system, the
Networking CO line that is used for the transferring voice path is not needed. That is, the
transfer call will be setup as an intercom call.
• The net transfer will be canceled when the transferring Station User presses the flashing
[TRANS/PGM] button.
• After the transferring Station goes on-hook, the net transfer call will not recall to the
transferring Station though the transferred-to Station.
• If all CO lines are in use, an error tone will be heard when a net transfer is attempted.
• If the call is transferred to a busy station, the busy tone will be heard.

Security of Transit-Out Code with registered IP
When the system receives a setup packet for the Transit-Out feature from the VOI CO line, the
system can check the setup packet with the registered IP as to whether this packet is valid or not.
If [TRANSIT-OUT SECURITY] Admin is set, the received IP in all received setup packets for
the transit-out feature will be checked with the registered IP, and if this IP is verified, the
transit-out feature will be invoked.
Verification is comparison with received IP in setup packet and registered IP: the system
compares received IP number with all registered CPN Info IP at the NET Number table
(PGM324).
If [TRANSIT-OUT SECURITY] Admin is set, and if received IP in setup packet does not match
with chosen IP numbers, this call will be disconnected automatically.
