1 Introduction
1.1 Overview
A VoIP GSM/CDMA/WCDMA Gateway is a device which reduces costs when
calling from a fixed telephone line to mobile network. It enables direct routing
between IP, digital, analog and mobile networks.
GSM/CDMA/WCDMA Gateway is now used more and more for telephone carriers
to land their IP calls to mobile network. In those areas where fixed line services
are unavailable or much more expensive than the mobile cost,
GSM/CDMA/WCDMA Gateway is an irreplaceable alternative.
The following figure shows a basic topology of GSM/CDMA/WCDMA
Gateway usage.

STUN
STUN is a standardized set of methods and a network protocol to allow an end host to
discover its public IP address if it is located behind a NAT. It is used to pemit NAT
traversal for applications of real-time voice, video, messaging, and other interactive IP
communications.
If you have the STUN server,enable STUN support,fill the server ip and port(default
port is 3478),it will work.The screenshot below shows the operation mode to Proxy
Encryption

Opptel Co., Ltd web: www.opptel.com E-mail: [e-mail]
17
Proxy Encryption is a good solution for protecting ip from blocking and save bandwidth
about 50%. Fields are specified as following:
Proxy Encryption: Specify whether enable it, if enabled, system will automatically
disable common encryption.
Proxy Server IP: Specify the proxy server ip.
Proxy Server Port: Specify the port of the proxy server, the default proxy server port
is 38080.
Transport Protocol: Specify the transport protocol. Option values are UDP/TCP,UDP
has better voice quality, TCP is more security.
Encryption Method: Specify the encryption method, the default encryption method
RC4,other two method are XOR and BASE128.
Encryption key: Specify the encryption key.
The Screenshot below shows the operation mode to SIP Account
If a default Phone Number, Account and Password is already set in Basic
Settings page, all the inputs here can be left empty and the default setting will
apply to all the SIP accounts. For example, if an account test is set with
password 888888 in Basic Settings page and all the SIP accounts

Opptel Co., Ltd web: www.opptel.com E-mail: [e-mail]
18
here are left empty, the combination of test and 888888 will be used for all SIP
accounts to register to SIP Server. When the gateway register on the server
successfully, the status will show ready.
There are two ways to overwrite the default SIP account setting in Basic Settings page.
1) Assign an account and password to Port 1 and leave empty for other Ports.
Settings of Port 1 can also be applied to all the other Ports automatically.
This is for short to set Account and Password if all the Ports use the same
value.
2) Assign account and password to certain Port(s). The value of account and password
can be various. In this scenario, only the Ports assigned with account and
password will register to SIP Server.
