SIM-server QuickStart has been added to the WIKI

SIM-server “QuickStart” manual has been added to website with documentation for Polygator products.


The document includes a step-by-step description to start a minimal set of hardware and software in order to enable the GSM-gateway obtain SIM-cards «virtually» from remote SIM-bank storage.

The Minimal set to create SIM-server complex includes: 1 GSM-gateway, 1 SIM-bank and Linux-server, with «Polygator SIM-server» software installed. The document lists the main steps to perform via SIM-server web-interface. Please note: SIM-server devices address space must provide «visibility» of all devices from SIM-server IP-address.

SMS-gateways Polygator: boxed G8/G20 and GSM-boards PCI/PCI-e

SMS-gateways Polygator: boxed G8/G20 and GSM-boards PCI/PCI-e

SMS-gateways Polygator are able to provide full-featured processing of Incoming/Outgoing SMS, delivery reports and USSD-commands support. Standalone SMS-gateway G8/G20 enables from 4 to 24 SIM-cards available in GSM-network concurrently. By using PCI/PCI-e GSM-boards it is possible to achieve much more SIM-cards per one device ratio. Currently SMS-gateways Polygator support following protocols and scenarios (but not limited to):



SMPP (Device as SMPP-server. Receive/Send SMS)
- single SMPP login/pass per device; possible to choose GSM-channel based on sender name; channels engaged consequently from #1 to the last one and again start from #1; it is possible to route SMS to channels based on recipient phone number prefix



AT-commands (Device as pool of Ethernet-modems. Receive/Send SMS)
- via TCP/IP and АТ-commands you obtain full control over each channel of the gateway. Each GSM-channel is accessible via IP-address:port



Email-to-SMS/SMS-to-Email (Device receives emails and sends as SMS, receives SMS and sends as emails. Receive/Send SMS)
- connection to external POP3-server (i.e. gmail). Receiving new e-mails and forwarding as SMS to the recipient indicated in the subject
- connection to external SMTP-server (i.e. gmail). Receiving new SMS and forwarding to e-mail recipient, indicated in GSM-channel settings



SMS-via-SIP/Simple SIP protocol (GSM-board controlled by Asterisk. Receive/Send SMS)
- it is possible to setup Simple SIP support and VoIP concurrently by additional settings on an Asterisk server and by using featured software on the client device



Flat-file database SQLite (GSM-board controlled by Asterisk. Receive/Send SMS)
- via SQLite database located on Asterisk server, it is possible to read incoming SMS and place SMS-records for sending by interacting with appropriate DB tables



HTTP-protocol and other ways (on incoming SMS or on incoming Call, device executes user script (bash, PHP, …) located in Linux file-system of the Gateway device. Receive SMS and Call notifications)
- there is a sample bash-script present for automatic sending incoming SMS to external IP-address (or Host) as a JSON-object by executing Curl command. There is a restriction for SMS body length – 100 symbols.



With third-party software:
- it is possible to interact with GSM-channels of gateway as with local COM-ports
- the device can be connected as one or several GSM-channels to server software
- on-board OS Linux allows to install additional software and extend functionality of the device
There are many Free and Commercial SMS-software available. Send us request to obtain our latest SMS-related software shortlist.



With SIM-bank/SIM-server solution:
- even with small gateway it is possible to use hundreds of SIM-cards comfortable
- it is possible to make balance control for SIM-cards and SIM-card replacement automatic
- SIM-card commutation is controllable via API-interface of the SIM-server software in “manual commutation” mode
- various aspects of SIM-server functionality are controllable via extensive SIM-Server API

How to find IP and other settings of the gateway?

Normally you would know an IP-address of the gateway on shipment or from referencing WIKI

However, what if you are getting back to the device sometimes later after certain changes was made?

One of the ways to acquire device setting is browsing system USB-flash on some computer.


How to find IP and other settings of the gateway?


The system USB-flash is formatted as ReiserFS so you can read it anywhere just by installing supporting software. Of course, you should avoid re-formatting USB-flash and performing any disk-checks, as may be advised by some host OSes. You absolutely need to keep it as original. Further, with the help of certain Win/Mac/Linux utilities you can reach any files for reading.

For example, on Windows you can use DiskInternals Freeware Linux Reader or YAReG.

How to find IP and other settings of the gateway?


To find an IP-address of the GSM-gateway you navigate to /etc/rc.d/ and browse the file until you see "echo LAN mode" text. This section lists your current network settings.

The same way you can jump to config-files of native SIP-client (SipUA) as well as to Asterisk main config-files such as extensions.conf and sip.conf.

SMS via SIP/Simple with GSM-card Polygator

SMS via SIP/Simple with GSM-card Polygator

For users of PCI/PCI-e GSM-boards Polygator under IP-PBX Asterisk it is possible to use SIP/Simple protocol for SMS messaging.

The SIP/Simple implements instant messaging via SIP.

Wikipedia link


The Asterisk-module of GSM-board Polygator implements its SMS-features via an Asterisk dial-plan that is why there is a way to setup receiving/sending SMS via the Simple protocol.

By using this feature, it is possible to turn a smartphone or even tablet PC without GSM-module into full-featured terminal for GSM-calls and SMS.

SIM-server API for custom VoIP and SMS-solutions

SIM-server API for custom VoIP and SMS-solutions

The SIM-server enables a flexible approach to SIM-cards management in VoIP-solutions (voice) as well as in SMS-solutions. It allows avoiding physical SIM-cards insertion into GSM-gateways and replaces it by logical «virtual» insertion of SIM-cards in gateway’s channels. Use of SIM-server technology dramatically expands the sphere of application for GSM-gateways, opens new possibilities for system scaling and for solving new tasks.

The multifunctional API for SIM-server management is available. It supports two main operating modes – AUTO-commutation mode and MANUAL-commutation mode. In the AUTO mode, the system initiates commutation of free SIM-cards automatically according to parameters set in advance. In the MANUAL mode commutation made only after receiving a certain API-command. The API SIM-server enables user to build high complexity system and create solution for non-standard task.

The gateway connected to the SIM-server keeps its normal features working. It can be interacted by user or by third-party software via the same VoIP and SMS-protocols and the same way as when SIM-cards inserted directly in the device.



To receive a general consultation on SIM-server technology, its application for solving your task and for getting DEMO-access, please let us know by contacts on our website!

Update: SMPP multi-accounts in G8/G20 gateways

Update SMPP multi-accounts in G8/G20 gateways

Feature of sending, receiving of SMS and DLRs by means of SMPP is present in G8/G20 gateway since very first firmware versions. This way gateway acts as basic SMPP-server. One of the unique SMPP-server features provided by recent firmware updates is multiple account support.

Ability to create several SMPP-accounts in one gateway allow assigning GSM-channels explicitly to user-accounts. This feature enables you to split GSM-channels between remote users, give channels for rent etc.

Each user establishes independent SMPP bind (in transceiver mode) and exchange data with device by it. Each channel of gateway is able to work via SMPP and concurrently perform VoIP-GSM calls, as well as use virtual SIM-cards from SIM-Server solution.

GSM-gateway with Asterisk v11 on-board

GSM-gateway with Asterisk v11 on-board

Thanks to the updated software module Polygator PGGSM (providing integration of radio-channels to Asterisk) the Asterisk v11 now can be installed directly on the GSM-gateway.

The integration module Polygator PGGSM provides GSM-gateway channels control via dial-plan and console of Asterisk, as well as command line of OS Linux.

All GSM-gateways Polygator are able to run Asterisk on-board, making it possible to use the gateway as standalone IP-PBX "all-in-one" as well as GSM-Gateway at the same time. Depending on the gateway software module type the highest on-board Asterisk version may vary. Currently, all gateways managed by “PGGSM” software support installation of Asterisk v11. All GSM-gateways managed by “Polygator GUI” software are able to run Asterisk up to v1.6.2.2 on-board.

In any case it is enough to run just one GSM-gateway box Polygator with Asterisk on-board to create the telephony server.
