Configure SIP register server IP address.
Register Server Configure SIP register server signal port.

Netphonic Systems NG-48UserManual
15
Port
Register
Username
Configure SIP register account（usually it is the same
with the port number that configured, some special
SIP servers will have different port configurations,
then the port configuration needs to be configured to
be numbers, here the configuration account can be
arbitrary character string）.
Register
Password
Configure password of SIP register account.
Proxy Server
Addr
Configure proxy server IP address（usually SIP will
provide user with service of proxy server and register
server which have the same configuration, so the
configuration of proxy server is usually the same
with that of register server, but if the configurations
of them are different(such as different IP addresses),
then each server’s configuration should be modified
separately.
Proxy Server Port Configure SIP proxy server signal port.
Proxy Username Configure proxy server account.
Proxy Password Configure proxy server password.
Local SIP Port Configure local signal port, the default is 5060（this
port will go into effect immediately, the SIP call will
use the modified port for communication after
modification）.
Register Expire
Time
Configure expire time of SIP server register, the
default is 600 seconds. If the expire time that server
requires is more or less than that configured by the
gateway, the gateway can automatically modify it to
the recommended time limit and register.

Netphonic Systems NG-48UserManual
16
Detect Interval
Time
Configure detection interval time of the server, if the
gateway enables SIP detection server function, the
gateway will detect once for whether the server has
response every other detection interval time.
Domain Realm Configure SIP domain, which is provided by SIP
Server. It can be the server IP (e.g. 202.112.10.12 );
or the domain name of the server(e.g. sipconcet.net);
or other identifier provided by the server(e.g. sip).
If SIP domain is same with server address, it doesn’t
display.
DTMF Mode
DTMF sending mode configuration; three kinds: the
above are basic configurations of SIP.
RFC Protocol
Edition
Enable the gateway to use protocol edition. When the
gateway need to communicate with gateways which
is using SIP1.0 such as CISCO5300 and so on, then it
should be configured into RFC2543 to communicate
normally. the default is to enable RFC3261;
User Agent To be compatible with some special SIP Servers, the
gateway has made some changes:
Net2phone: server demands to use the MAC address
as user agent;
shengji: walkersun and ipgw use special encrypt;
japan050: use the default value “common”.
Enable Register Configure enable/disable register;
Enable Pub
Outbound Proxy
Configure to enable public outbound proxy. If proxy
server has been enabled, the gateway will consider
the user as using outbound proxy automatically. If the

Netphonic Systems NG-48UserManual
17
configuration has been disabled, the gateway can still
be registered to the server, but can’t make SIP call;
configuration of registered call by the gateway will
not have impacts on SIP point-to-point call;
SIP(Default
Protocol)
Configure SIP of the gateway as default protocol;
Auto Detect
Server
Configure automatic detection server of the gateway;
Server Auto Swap Configure main and backup auto-swap server; if the
gateway enables main and backup server function,
the automatic detection and auto-swap functions
should both be chosen.
Note: if you want to register and call through server, you must
configure corresponding numbers (which are usually SIP accounts)
to local port, otherwise the gateway will reject for sending out
register message when it considers that there is no number.
4.4.3 Phone number
After the aforesaid network and VoIP configuration, if the network can
communicate correctly, the user should be able to make VoIP calls
through the register and proxy.
After submitting the configuration, if the status is still incorrect, click
the menu in the left to renovate. Please do not click the “apply”
continuously, since some ISP may inhibit the gateway to register or
cancel continuously. If users click “apply” continuously, or register
and cancel frequently, the server may stop response, this will make the
gateway can not receive the certifications of register/cancel request
and show error register status!

4.5 Advance configuration
4.5.1 Net Service configuration
User can set up Telnet, HTTP, RTP port on this page and view DHCP
table.

Netphonic Systems NG-48UserManual
19
Configuration explanation:
HTTP Port Configure web browse port, the default is 80 port, if
you want to enhance system safety, you’d better
change it into non-80 standard port.
Telnet Port Configure telnet port, the default is 23 port.
RTP Initial Port Enable RTP initial port configuration. It is dynamic
allocation.
RTP Port Quality Configure the maximum quantity of RTP port. The
default is 200.
Leased IP
Address
Leased IP-MAC correspondence table of DHCP.
Note:
1) The configuration on this page needs to be saved after modified
and will go into effect after restarting.
2) If the Telnet, HTTP port will be modified, the port is better to be
set as greater than 1024, because the 1024 port system will save

Netphonic Systems NG-48UserManual
20
ports.
3) Set the HTTP port as 0, then the http service will be disabled.
4.4.2 SIP advanced configuration
Set SIP STUN, private and backup server, user password and so on.
SIP STUN is a kind of server that used to realize the SIP’s enablement of
NAT, when the STUN server IP of the gateway has been configured
(generally the default is 3478) and Enable SIP Stun has been selected,
conventional SIP server can be used to realize the gateway’s penetration
of NAT.
Public backup server can implement the proxy of the dialogue machine
through auto-swap function when no response to public server. When the
gateway detects response of public server, it will auto-swap to public
server. Public backup server is redundancy backup of public server, it
should have the same account with public server.
The gateway’s supports to two different kinds of SIP server concurrently
can be implemented on private server. In this way user can register and
use two different kinds of services concurrently.
