Description
1. RTP Self Port 1024~65528
(Even numbers
only)
3462
Available
Not available
The number of the port receiving RTP
data.
At default this is assigned to port 5060.
The First IP phone on this local LAN can
use this port. The second IP phone
would need to be changed to port 5062.
2. SIP Self Port
1024~65535
5060
Available
Not available
The number of the port receiving SIP
data.
At default this is assigned to port 3462.
The first IP phone on this local LAN can
use this port. The second IP phone
would need to be changed to port 3464.

ECTION
2 CONDITIONS
• The NAPT feature supports CPU software V1.00 or higher.
• Terminals using NAPT must be at firmware V1.0.0.0 or higher.
• IP terminals can be connected via NAT router or WAN (direct connection).
• The NAT router on the SL2100 side must have a static WAN IP address.
• The software change Programs 15-05-47 and 15-05-48 to a shorter interval. These programs are
changed on a per station basis. Non NAPT phones will still use Programs 84-23-01 and 84-23-02
while only NAPT phones will use Programs 15-05-47 and 15-05-48.
• It is necessary to set Program 10-46-14 to
OFF
when the VoIPDB is assigned a global (public) IP
address.
• When Program 10-46-14 is set to
ON
, it references programs 10-58-01 and 10-58-02. These
programs are used to define any destination networks that do not get sent through the NAPT
translations.
• UDP ports in the remote routers may be required to be forwarded to the IP Terminals.
• NAPT can be used for SIP trunks and terminals on the same system.
S
ECTION
3 RESTRICTIONS
• With static NAT, the terminal needs a static IP Address assigned to it, or entries in the DHCP must
be made to provide the same IP Address to the terminal.
• The NAT router on the terminal side must have the function for setting up static NAT.
• A conversion table must be manually set up for the NAT router on the terminal side.
• If installing multiple terminals in the domain of the NAT router on the terminal side, the RTP Self port
and SIP Self port for each terminal must be specified so as to avoid overlapping.
• The SIP server cannot be switched. (Only one address can be registered as the SIP server.)
Dynamic NAT
• The NAT router on the terminal side must have the function for setting up dynamic NAT.
• It is assumed that port numbers are not changed by the NAT router on the terminal side. If a port
number is changed by NAT router, NEC does not guarantee proper operation.
• If installing multiple terminals in the domain of the NAT router on the terminal side, the RTP Self port
and SIP Self port for each terminal must be specified so as to avoid overlapping.
• The SIP server cannot be switched. (Only one address can be registered as the SIP server.).
