SS-16 VoIP-2-GSM USER MANUAL
DOC. NO: SS-16-14 (REV. 02) Page 4 of 84
REASON FOR THE INTRODUCTION OF THIS PRODUCT:
- To complete the line of SS-16 products
SS-16 VOIP-2-GSM is a new member of the SS Telecoms family of
gateways. It is a compact variant of the classic VoIP to mobile gateway,
featuring just two mobile modules and an ETH port. While previous SS
devices connected analogue (FXO/FXS) or digital (ISDN NT/TE) phone ports
to mobile networks, this one has a Voice over IP port, since it was designed to
convert outgoing and incoming calls from VoIP to mobile.
The purpose remains the same, cutting down the costs of cellular calls, but
the new mobile-2-VoIP interface with LCR capabilities represents a new
approach in convergence between VoIP and home or corporate mobile
communications.
By interfacing between mobile networks and IP it allows end customers to
benefit by saving costs, while its two modules design provides scalability and
flexibility.
- To extend the range
While the analogue or digital devices equipment allowed connections to
phone terminals or PBX’s located a few meters or up to 1000m away, with
SS-16 VOIP-2-GSM the length of the connection becomes infinite. The mobile
gateway may be located anywhere in the world and still perform an interface
task.
Support, debugging and firmware upgrading can also be performed faster and
from a longer distance. Previous versions of the products were connected to a
local computer via serial RS-232 or USB cable. This allows management of
the device, using an OAM program, sending/receiving SMS and diagnostic or
update of the firmware. These operations had to be performed from the
computer connected to it!
With this new SS-16 VOIP-2-GSM, it can be in anywhere in the world. The
professional who performs debug or update of firmware connects to it
remotely, via IP networks.
Intended use
SS-16 VOIP-2-GSM was intended to provide cost-effective access to mobile
networks for the SIP users registered to the SS Telecoms IP-PBX.
Using the SS-16 VOIP-2-GSM can be beneficial for home users too, but it
was intended for office use, both for companies that have many foreign
affiliates and for small to medium companies that already own an IP
infrastructure. Companies with international offices can use one or several
SS-16 VOIP-2-GSM devices at each location - the calls will be routed as VoIP
via Internet to the respective locations where they will be terminated as local
GSM calls to the respective mobile networks, with minimum costs.

SS-16 VoIP-2-GSM USER MANUAL
DOC. NO: SS-16-14 (REV. 02) Page 5 of 84
Enterprises with existing IP infrastructure will use the SS-16 devices to
terminate the calls to mobile networks, achieving substantial savings on
outgoing and incoming calls from IP to GSM networks and vice versa.
It can also be used by providers, ensuring low-cost call termination at different
locations throughout the world. VoIP calls originating from anywhere can be
sent via Internet to be terminated through SS-16 VOIP-2-GSM devices
located at the corresponding sites. The respective SS-16 VOIP-2-GSM
devices will then directs the calls to the required local GSM network, with the
minimum possible cost.
Flexible Usage
SS-16 VOIP-2-GSM can be used in several ways:
-with an IP PBX that has SIP subscribers;
-with hardware SIP telephones,
-with soft phones, such as the free application SJ Phone.
In order to ensure correct installation/configuration and good operation of the
SS-16 VOIP-2-GSM device, the manufacturer strongly recommends the study
of this manual before attempting operation.

4.3 SOFTWARE INFORMATION
The Web interface displays some of the information described above, but also
important additional information, which is NOT available through the adhesive tags.
Such information is related to the serial of the motherboard of the device, or the
software version actually running on it.
Two categories of information are displayed:
-System info, with temporary (current) data, such as uptime, load and Ethernet
link status. -
-Device info, permanent, which is important for this chapter – Firmware and kernel
versions.
The permanent identification info shown refers to the following elements:
-Firmware version: version of the application firmware running on SS-16 VOIP-2-
GSM: you may see “Firmware version is SS-16-1.1.41-M2P-SBT. The firmware
can be easily updated (a new version) or upgraded (new software features added);
-Kernel version (Operating system version), such as system-1.0.5-MXX-SAT in the
example above. The application firmware and the operating system (root or kernel)
may be updated separately, according to the requirements of the users. The
operating system memory is write-protected, thus in case of problems, accidental
erasing or power failure during updating, there is still a functional “kernel” allowing
loading of a new software image;
System Status
The information about current firmware and kernel can be found in the option Status –
System Information of the menu page SYSTEM, as shown next.
For this you must access the System> Status page. Just enter into the browser the
