1. Overview
What is VS-GW1202-4G?
OpenVox VoxStack Series GSM Gateway is an open source asterisk-based GSM VoIP Gateway
solution for SMBs and SOHOs. With friendly GUI and unique modular design, users may easily
setup their customized Gateway. Also secondary development can be completed through AMI
(Asterisk Management Interface).
There are three models with VoxStack series GSM Gateway WGW1002G, VS-GW1202-4/8G and
VS-GW1600-20G. There are 2 GSM channels in WGW1002G and 4/8 GSM channels in
VS-GW1202-8G. The Modular Design GSM Gateways are ranging from 4 up to 20 GSM channels on
the VS-GW1600 series gateways, developed for interconnecting the GSM cellular networks with a
wide selection of codecs and signaling protocol, including G.711A, G.711U, G.729, G.722, G.723,
G.726 and GSM to quickly reduce communication expenses and maximize cost-savings. With the
unique design of the VoxStack gateway, it can support hot-swap for both SIM cards and GSM
gateway modules. Users can simply add or remove the modules for hardware expansion or
exchange.
The VoxStack gateway designs with 2 LAN switch boards to provide stack ability on the hardware
upgrade, and five VS-GWM400G modules which are independent with each other, so each one has
a GUI configuration web. If you connect to ETH1, you can access Board 1 only and access other
boards with different port numbers which can avoid IP conflict. Otherwise if you connect to ETH2,
you can access different Boards with different IP addresses.
Our products support SMS messages sending, receiving, group sending and SMS to E-mail. The
GSM gateway will be 100% compatible with Asterisk, Elastix, trixbox, 3CX, FreeSWITCH SIP server
and VOS VoIP operating platform.

every module one by one. Now we offer you two ways to access to your gateway. There are two
RJ45 Network ports on the board, ETH1 and ETH2. They are different. If choose ETH1, you can
access Board 1 only, then access to other boards with different port numbers but the same IP
address, this will help to avoid IP conflict. If you choose ETH2, you can access different Boards with

PDD
Post Dial Delay (PDD) is experienced by the originating customer as the
time from the sending of the final dialed digit to the point at which they
hear ring tone or other in-band information. Where the originating
network is required to play an announcement before completing the call
then this definition of PDD excludes the duration of such announcements.
ACD
The Average Call Duration (ACD) is calculated by taking the sum of billable
seconds (bill sec) of answered calls and dividing it by the number of these
answered calls.
ASR
Answer Seizure Ratio is a measure of network quality. Its calculated by
taking the number of successfully answered calls and dividing by the total
number of calls attempted. Since busy signals and other rejections by the
called number count as call failures, the ASR value can vary depending
on user behavior.

renew all outbound registrations when the monitor detects any sort of
network change has occurred. By default this option is enabled, but only
takes effect once res_stun_monitor is configured. If res_stun_monitor is

Premature Media
Some ISDN links send empty media frames before the call is in ringing or
progress state. The SIP channel will then send 183 indicating early media
which will be empty - thus users get no ring signal. Setting this to "yes" will
stop any media before we have call progress (meaning the SIP channel will
not send 183 Session Progress for early media). Default is 'yes'. Also make
sure that the SIP peer is configured with progressinband=never. In order
for 'noanswer' applications to work, you need to run the progress()
application in the priority before the app.
