1. Introduction
Product Overview
The stand-alone Nateks Networks VoiceCom90 SIP Router carries both voice and facsimile
over the IP network. It supports SIP industry standard call control protocol to be compatible
with free registration services or VoIP service providers’ systems. It works in two different
modes: UA (User Agent) or Server. As a standard user agent, it is compatible to all
well-known Soft Switches and SIP proxy servers.
There are 5 models of VoiceCom90 in the same series: VC-91-2, VC-91-1, VC-92-3, VC-92-2,
and VC-92-1. VoiceCom90 can be seamlessly integrated to existing network by connecting to
aphone set, fax machine or PSTN line. With only a broadband connection such as ADSL
bridge/router, Cable Modem or leased line router, it allows you to gain access to voice and
FAX services over the IP in order to get the convenient of VoIP and reduce the cost of
international and long distance calls.
In addition, the in-built router supports comprehensive Internet gateway functions to
accommodate other PCs or IP devices to share the same broadband stream. QoS function
allows voice and data traffic to flow through where voice traffic is transmitted in the highest
priority. With TOS bit enabled, it guarantees voice packets to have first priority to pass
through a TOS enabled router.
With the support of DDNS, it makes VoiceCom90 reachable by its domain name where the
ISP dynamically assigns the IP address.
VoiceCom90 can be assigned with a fixed IP address or by DHCP, PPPoE. It adopts the G.711,
G.729A or G.723.1 voice compression format to save the network bandwidth while providing
real-time and toll quality voice. In addition, in the event that the power supply fails or Internet
connection is lost, VoiceCom90 can automatically divert the FXS end to the PSTN network on
the PSTN port so users can still use the conventional PSTN line to make calls. This feature is
especially useful while dialing emergency calls (i.e. 911).

Hardware Connections
The diagram shows how VoiceCom90 connects to other devices in your network.
1. PSTN: Available in VC-91-1, VC-92-1 and VC-92-3 only. Connect to your original telephone
line on the wall jack with RJ-11 cable.
2. DC+12V: Connect to the bundled power adaptor. Plug power adapter to a proper power source.
3. Phone: Connect to your analog telephone. These are FXS (Foreign Exchange Station) ports.
4. LAN: Connect to a PC for later VoiceCom90 configuration.
5. WAN: Connect to your broadband device with RJ-45 cable.
Note: Do not connect Phone port directly to your original telephone line. This may cause
damage to VoiceCom90.

3. Setting the VoiceCom90 through IVR
VoIP transmits voice data (packet) via the Internet to achieve telecommunications. This means
that the telecommunication quality is closely related to the whole network environment. If any
one of the telecommunicating parties has insufficient bandwidth or frequent packet loss, the
telecommunication quality will be poor. Therefore, an excellent telecommunication can only
be created when VoiceCom90 is connected to the Internet and when network environment is
stable.
Preparation
Install the VoiceCom90 according to instructions. Connect the power supply, telephone
set, telephone cable, and network cable properly as described in Chapter 2.
If a static IP is used, confirm the desired 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 users wish to build VoiceCom90 under the NAT, VoiceCom90 WAN Port IP address
and LAN Port should not use the same range. This is to avoid phone failures.
IVR (Interactive Voice Response)
VoiceCom90 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 settings, make sure the new settings are saved. This is so that the
new settings will take effect after the system is restarted.
