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
Proxy Server
Addr
Configure password of SIP register account.
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.

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.
15
Page 16
Netphonic Systems NG-48 User Manual
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
Configure to enable public outbound proxy. If proxy
Outbound Proxy
server has been enabled, the gateway will consider
the user as using outbound proxy automatically. If the
16
Page 17
Netphonic Systems NG-48 User Manual
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
Configure SIP of the gateway as default protocol;
Protocol)
Auto Detect
Configure automatic detection server of the gateway;
Server
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.
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!

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
19
Page 20
Netphonic Systems NG-48 User Manual
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.

4.6 Number binding configuration
Number IP table configuration:
Function of number IP table is one way to implement the gateway’s
calling online, and the calling of the gateway will be more flexible by
configuring the number IP table. For example, user know the other
party’s number and IP and want to make direct call to the party by
point-to-point mode: the other party’s number is 1234, make a
configuration of 1234 directly , then the gateway will send the called
number1234 to the corresponding IP address; Or set numbers with prefix
matching pattern, for example, user want to make a call to a number in a
certain region(010), user can configure the corresponding number IP as
010T―― protocol―― IP, after that, whenever user dial numbers with
010 prefix( such as 010－62201234), the call will be made by this rule.
Bases on this configuration, we can also make the gateway use different
accounts and run speed calling without swap.
When making deletion or modification, select the number first, then click
Modify and complete the operation.
Configuration explanation:
1) The Table displays calling number IP image list.
2) Click “Add”, a figure will be shown at the lower part of the page, of
which:
27
Page 28
Netphonic Systems NG-48 User Manual
Phone Number It is to add outgoing call number, there are two kinds
of outgoing call number setup: One is exactitude
matching, after this configuration has been done,
when the number is totally the same with the user’s
calling number, the gateway will make the call with
this number’s IP address image or configuration;
Another is prefix matching （be equivalent to PSTN’s
district number prefix function）, if the previous N
bits of this number are the same with that of the
user’s calling number (the prefix number length),
then the gateway will use this number’s IP address
image or configuration to make the call. When
configuring the prefix matching, letter "T" should be
added behind the prefix number to be distinguished
from the exactitude matching; the longest length is 30
bits.
Call Mode Configure the calling mode: H323,SIP .
Destination Configure destination address, if it is point-to-point
call, input the opposite terminal’s IP address, it can
also be set as domain name and resolved the specific
IP address by DNS server of the gateway. If no
configuration has been made, then the IP will be
considered as 0.0.0.0. This is an optional
configuration item.
Port Configure the other party’s protocol signal port, this
is optional configuration item: when nothing is input,
then the default of h323 protocol is 1720, the default
of sip protocol is 5060.
Alias Configure alias, this is optional configuration item: it
is the number to be used when the other party’s
number has prefix; when no configuration has been
made, shown as no alias.
28
Page 29
Netphonic Systems NG-48 User Manual
alias can be divided into four types, it should be
combined with replacing length to make the setup:
Add: xxx, add xxx before number. in this way it can
help user save the dialing length;
All: xxx, the number is all replaced by xxx; speed
dialing can be implemented, for example, user
configure the dialing number as 1, with the
configuration "all" , the actual calling number will
be replaced;
Del, delete n bit in the front part of the number can
be decided by the replacing length; this configuration
can decide the protocol for appointed number;
Rep: xxx, n bit in the front part of the number will be
replaced. n is decided by the replacing length. For
example, user want to dial PSTN（010－62281493）
by VoIP’s voice over service, while actually the
called number should be 8610－62281493, then we
can configure called number as 010T,then rep: 8610,
and then set the replacing length as 3. So that when
user make a call with 010 prefix, the number will be
replaced as 8610 plus the number and then sent out.
It is a convenient thinking mode for user to make a
call.
Suffix Configure suffix, this is optional configuration item:
it is the additive dial-out number behind the number;
when no configuration has been made, shown as no
Delete Length
(optional)
suffix.
Configure the replacing length, replace the number
that user input according to this length; this is
29
Page 30
Netphonic Systems NG-48 User Manual
optional configuration item.
3) Click “Delete”: Delete selective number IP image;
4) Click “Modify”: Choose a corresponding phone number image in the
drop-down menu and then click “modify” to make modification. Then the
page changes to the following chart. After modification, click “Submit” to
go into effect.

The basic application of the number IP table has been introduced, now let
me introduce how to configure IP table of number to implement
configuration of using multi-accounts concurrently:
For example, now user has a H323 account and two SIP accounts, then
30
Page 31
Netphonic Systems NG-48 User Manual
under the default condition, user can only make calls by the default
protocol. Configure the number IP table to select the call protocol, then
user don’t need to select default protocol before making calls every time.
The configuration process will not be repeated, now I will mainly
introduce what kind of number IP image can implement this function.
By configuration, image table as follows will be gained:
Image of 9T means when user configure public SIP server and register,
then user just need to add a “9” before the calling number whenever
