Port forwarding does not need to be assigned at the Remote Terminal locations.
• IP7[ ]-8IPLD-C1 terminal Setting of "NAT Traversal Mode" needs "Dynamic". "Static" is unsupported.
• Port Forwarding setting to system side Router A is necessary.
• When PRG 15-05-45 is set to 1 the manual table setting for port forwarding is unnecessary at
remote side Router B, but it needs NAT function setting itself. If PRG 15-05-45 is set to 0 then port
forwarding at the Remote side router is required. This feature requires installation of a VoIPDB.
• Depend on the router it may close the port being used if packet exchange is not performed during a
certain time frame. In this case change PRG 84-23-01 and PRG 84-23-02 to a shorter interval.
• SIP ALG function of ALL routers in the network must be disabled.
• The SL2100 Desktop Application does not support Network Address Translation(NAPT). If a user
would like to connect the Desktop Application through an Internet Connection the use of a VPN will
be required.
• If there is excessive packet loss on the network, IP phones will play a warning tone during
conversations. To disable this tone set PRG 15-05-31 to "0".
• Multicast RTP is not supported.
• Peer to Peer is possible only between the IP Terminals under the same router.
• NAPT is supported for NEC IP Multiline Terminal and all other third party Standard SIP terminals by
this feature.
• After starting SIP negotiation for the call if any RTP packet can't be received from the terminal within
10 seconds, the call is dropped and IP Terminal indicates below notice on the LCD.
• Each NAPT terminal can have a separate Register and Subscribe expire timer.
