SIP Operation Manual
3. Setting the Gateway through IVR
VoIP transmits voice data (packets) via the Internet. One effect of this is that telecommunications
quality is closely related to the condition and status of the network environment. If any of the parties
involved in VoIP communications has insufficient bandwidth or frequent packet loss, the
telecommunication quality will be poor. Therefore, excellent telecommunication can only happen
when the gateway is connected to the Internet and when the network environment is stable.
Preparation
Install the gateway according to instructions. Connect the power supply, telephone set,
telephone cable, and network cable properly as described in
Installation and
Applications
.
If a static IP is used, confirm the correct IP settings of the WAN Port (IP address, subnet
mask, and default gateway). Please contact your local Internet Service Provider (ISP) if
you have any questions.
If using dialup ADSL (PPPoE) for network connection, confirm the dialup account number
and password.
If you intend to operate the gateway under a NAT, the gateway WAN port IP address and
LAN port should not use the same range in order to avoid phone failures.
The gateway provides two setting modes:
1. Telephone IVR Configuration Mode
2. Browser
Configuration
Mode
The IVR provides basic query and setting functions, while the browser provides a full setting
function.
IVR (Interactive Voice Response)
The gateway provides convenient IVR functions. Users only need to pick up a handset and enter
the function code for the query and setting without using a PC.
NOTE: After finishing the setup, make sure the new settings are saved. This will enable the new
settings to take effect after the gateway is restarted.
