The GSM VOIP Gateway is a broadband relay gateway newly developed by
VinTelecom Technology. It is a new product for seamless connection between
the GSM network and VoIP network. When the mobile phone SIM card is
installed in the GSM VOIP Gateway, users can register the GSM phone to the
VoIP softswitch system. Through the GS M VOIP Gateway, users can realize the
uplink and downlink call s between the GSM network and the VoIP network. In
addition, the GSM VOIP Gateway supports the transparent tra nsmission of the
call er number from the PSTN to the VoIP. The
GSM VOIP Gateway features embedded SIP and H.323 protocols with flexible
setting. The bi-directional password authentication (call authorization) and trust
list authentication greatly minimize the risk of charge losses and the flexible
routing function can meet special requirements of various call forwarding. In
particular, the GSM VOIP Gateway supports multi device groups, with flexible
setting of large GSM gateway groups with different channel numbers. With its
low price, excell ent voice quali ty, and powerful features, the GSM VOIP
Gateway is the first choice for system in tegrators, traffic operators, and softswi t
ch manufacturers.
The GSM VOIP Gateway includes WT-2201, WT-2204 and WT-2208.

3.5.7.2 Dialing Rule with Specified Length Of Numbers
If you need to specify the length of telephone nu mbers matched, you can specify
the dialing rule as “AAXXXXXX:-aa+bb”. Where, “AAXXXXXX” indicates the
number to match and the length of the number. “AA” indicates the head and
other numbers are represented by X or x. The digit s after the colon indicates
detailed actions to be taken on the number.
The setting is as follows:
In the above example 3, the rule is “00:|0:-0+00 86|:+0086755”, which can be
changed to “00:|0:-0+0086|[1-8]xxxxxxx:+0086755”.
It means that when you dial a number whose first digit is 1 to 8 and total length
is 8, the gateway will automatically dial the number and add 0086755 before the
number.
Examples:
"0:|13:+0|:+0755"
This rule enables the GSM VOIP Gateway to add 0 before the mobile phone
number and 0755 before the telephone number.
The above rule can be change to:
“0:|13[0-9]xxxxxxxx:+0|[1-8]xxxxxxx:+0755”
Similarly, this rule enables the GSM VOIP Gateway to add 0 before the mobile
phone number and 0755 before the telephone number. However, the length of
the mobile phone number is limited to 11 digits.
As shown above, the length of telephone numbers is limited to eigh t digits. 13[09]xxxxxxxx and [1-8]xxxxxxx represent mobile phone numbers 130xxxxxxxx to
139xxxxxxxx, and telephone number 1xxxxxxx to 8xxxxxxx, respectively.
Note: When the length of the number is specified, the exceeded numb ers will be
discarded if the length of the number exceeds the specified length. For example:
GSM VOIP Gateway USER MANUAL – Rev1 – Technical Support: [email protected]
added. If the number fails to match, the number continues to match the next
rule. If no digit after the colon is specif ied, such as “00:”, it ind icates that no
actions are taken when “00” is matched and the nu mber exit s the matching.
If no digit before the colon is specified, such as “+86755”, it indicates that
instead of matching, actions are taken on the number directly.
4. You can specify a range for matching of dialing rules. The rule forma t is “[AB]A:-aa+bb” or “A[A-B]:-aa+bb”. For example, you can specify the range of
numbers beginning with 2 to 8 as “[2-8]: -aa+bb” or numbers beginning with
13 to 15 as “1[3-5]: -aa+bb”.
Examples:
1. Rule: 0:|:+0755

network service quality.
E. DTMF Signals
DTMF signals are used to transmit call signal s to the call swit ching cen ter over the
audio band. The DTMF means that two different frequencies of sounds are
combined into 16 types of dialing tones. The telecom office or 1860 service
hotline identifies these dialing tones through analyzing the DSP, and thus
determines the dialing number. There are two types of DTMF signals: in-band
DTMF and out-band DTMF.
WT-2208 config by line
You need to set parameters for each line and the setting method is the same. The
setting parameters are as follows:
A) Telephone Number
This parameter is used to set the telephone number of the lin e. The telephone
number is an unique ID when the gateway serves as the caller.

The in-band DTMF transmit s dialing tones and call voices togeth er, without any
processing. Therefore, the in-band DTMF transmits DTMF signals through a s ingle
way.

The advance setting of the SIP involves the signaling and media. User s can set
according to their special requirements.
Select SIP Menu > Advance Setting/Media.
A. Signaling Port (SIP Local Port)
The SIP local port is the local U DP port. It is used for communications betw een
the SIP agent and the SIP proxy server as well as other SIP managers.
B. NAT Hold
This parameter is used to hold the port that is activated by the NAT for SIP
signaling communication. The unit of the parameter is m.

The gateway prefix enables the connection of call s throu gh a particular line. It
can match the first digit only. You can set a gateway prefix for multiple lines.
When you set a gateway prefix for mult iple lines, the call s that have the same
gateway prefix will select the line set with this ga teway prefix. For example, the
gateway prefix is 1. When the user dials 10086, the call will be connected by the
line with the gateway prefix 1. When the user dials 075588290211, the system
detects whether the line with gateway prefix 0 exists . If exists, the call will be
connected. Otherwise, the call will be released.
Note: When you set the GSM VOIP Gateway by lines, the gateway prefix must be
set. Otherwise, the call will not be connected .
C) SIP Proxy Server
This parameter is used to set the address of the SIP proxy server. If the SIP
proxy server uses the special port (other than the SIP default port 5060), yo u can
add the detailed port number at the end of the IP address or domain name of the
proxy server. For example, 192.168.2.26:3000 or hy.con.com:3000.
D) SIP Registration Server
The SIP login server is a server that the gateway registers the account. This
parameter is used to set the IP address or domain name of the SIP registration
server. If the SIP registration server uses the special port (other than the SIP
default port 5060), you can add the detailed port number at the end of the IP
address or domain name of the registration server. For example,
192.168.2.26:3000 or hy.con.com:3000.
E) Outbound Proxy
The outbound proxy is mainly used in the scenarios where the firewall or NAT
exists, so that the signaling and media stream can penetrate the firewall.
F) Homing Domain
This parameter is used for the domain management host of the SIP (a host that
provides the SIP service).
G) Authentication ID
This parameter is used to set the authentica tion account when the gateway logs
into the SIP proxy server.
GSM VOIP Gateway USER MANUAL – Rev1 – Technical Support: [email protected]
This parameter is used to set the authentication password when the gateway log s
into the SIP proxy server.
I) Display Name
When you call your friend John Smith, your name will be displayed on your
friend’s telephone.
J) Backup Server
This parameter is used for registration backup. When a backup registration server
exists in the user’s system, the user ca n enable this para meter. Whe n the ba ckup
server is enabled, the gateway will automatically log into the backup server in
case of the failure of the main server.
3.5.2.4 Trunk Gateway Mode
The trunk gateway is used to connect the VoIP network with the GSM network
and convert the related protocols, so that users served by the two networks can
call each other.
GSM VOIP Gateway USER MANUAL – Rev1 – Technical Support: [email protected]
It is the IP address of the server connected to the GS M VOIP Gateway. When the
registration timeout is 0, the GSM VOIP Gateway is connect ed to the SIP server.
If the registration timeout is not 0, the GSM VOIP Gateway logs into the SIP
Trunk Gateway1 server through setting the telephone number, authentication ID
and password.
B) SIP Trunk Gateway2
It is the IP address of the terminal con nected to the GSM VOIP Gateway, which
can be an IP segment, such as 192.168.2.X. This means that all terminals
connected over 192.168.2 segment can log into the GSM VOIP Gateway and land
through the direct connection between the GSM VOIP Gateway and the GSM
network.
C) SIP Trunk Gateway3
It is the IP address of the server connected to the GSM VOIP Gat eway.
D) Telephone Number
This parameter is used to set the telephone number of the lin e. The telephone
number is an unique ID when the gateway serves as the callee an d takes effect
when the GSM VOIP Gateway logs into the SIP Trunk Gateway1.
E) Registration Timeout (s)
When the registration timeout is 0, you cannot register the gateway and the
gateway will be connected to the server directly. You can reference the setting
parameters of the single server mode to register the gateway.
F) Authentication ID
This parameter is used to set the authentica tion account when the gateway logs
into the SIP Trunk Gateway1 proxy server. The parameter can b e null in the case
of interconnection.
G) Password
This parameter is used to set the authentication password when the gateway log s
into the SIP Trunk Gateway1 proxy server. The parameter can b e null in the case
of interconnection.
