Openvox is a company from China. It has long been no news that engineers from the sky can not only copy other people's ideas, but also create independent, effective and high-quality solutions.
You, as telephonists, are likely to be known as a manufacturer of PCI and PCI-E VoIP telephony boards. And I will add that this product line does not end there.

The company manufactures FXS routers, various embedded motherboards, analog and digital filers, and even telephone exchanges (on Asterisk, of course).
In Q3, OpenVox announced the expansion of its lineup of routers.
We offer you an overview of budget and sooo functional GSM gateways from OpenVox.
At the moment, the manufacturer introduced to the market three devices:
VS-GW1200-4G on 4 SIM cards,
VS-GW1202-8G on 8 SIM cards,

and the modular
VS-GW1600-20G .
VS-GW1600-20G expands with the help of special boards
VS-GWM400G
Each such board adds 4 GSM channels, i.e. You can build yourself a gateway for 4, 8, 12, 16 and 20 SIM cards. Conveniently, if you choose for yourself the path of a gradual upgrade.
OpenVox claims that on each such board lives its own, little asterisk. Do not be scared to start the gateway, you do not have to configure 5 separate stations. One, the head, the board takes control of the rest automatically.
These modules can be considered more thoroughly. The Altera Cyclone III FPGA is used as the controller for controlling the GSM channels, and to be more precise, the EP3C10 256-pin. Works in conjunction with GSM modules Simcom sim840w.
The main processor is a dual-core ARM MNDSPEED M83241G-13, which, according to the specification, runs at 450 MHz, supports DDR2-667 and has 2x128K cache of the first level. I think this is more than enough for this device.
TTX
Routers are made in durable metal housing. They remind of Soviet equipment, originally from the 70s. Honestly, the appearance - this is the last thing considered when choosing a device of this class, so that it can be forgiven the Chinese :)
One unit, half length. In the rack will enter one large gateway, or three small ones. Ears are not included.

- 2 10 / 100M LAN interface
- 4 SMA-K interfaces
- Usage temperature 0 ~ 40 ℃
- Air humidity 10% ~ 90% Non-condensing
- Power supply 12V, 4A. (included)
- Consumption: from 18 watts to 46 watts.
Device functionality
Gateways are running Asterisk. SIP (RFC3261) compatible, promise IAX2 support in the near future.
- DTMF support: RFC2833, Inband, SIP Info
- G.711A, G.711U, G.729 , G.723.1, G.722, G.726, GSM
- Echo cancellation: ITU-T G.168 LEC
- GSM 850/900/1800/1900 MHz & Band binding
- USSD transfer
- IMEI change
- API interface (AMI)
- Flexible routing, unlimited number of rules
- Support for their scripts and dialplans
- Configuration Backup
- Routing by least cost criterion LCR (by time, number)
- Static IP or DHCP
- Sending, receiving SMS
Everything is standard with the exception of the IMEI shift. The thing is useful, and is inherent in very rare devices.
Interface
System configuration is most conveniently done via the web interface. The device is initially available at 172.16.99.1 admin / admin. Gateway is also available via SSH if you enable the corresponding checkbox.
We are immediately greeted by the main screen with the status of the device. Here you can see information about connected SIM cards, call status (incoming / outgoing), connection of SIP accounts. The gateway, by the way, can not only register itself, but also assume the registration of other devices.

SMS sending
It is very trivial: drive in numbers for sending or load a ready list of numbers from a file, add text, press “send”. The gateway supports the API, and you can easily set up integration with the CRM system for
spamming . Cyrillic to receive and send supported.
Call RoutingSetting up GSM and SIP trunks is so simple that I will not dwell on them. Where it is more interesting to consider routing.

What => where. In addition, specify prefixes, mask, time and even a change of Caller-ID.
Asterisk CLI support for Guru Change configuration files, directly from the web interface Watching CDRs, executing AT commands — all of this as a matter of course. This is a modem in some sense :)
Conclusion
Of course, in any device you can find cons. OpenVox gateways are no exception. It does not support Vlan, and ACL. I would also like to see a firewall, even the simplest.
I wrote down the recommendations to the manufacturer, promised to work in this direction as soon as possible.
GSM routers OpenVox - must have! There is no one on the market who can provide similar functionality for such a price.
AddPac gateways are ideal, but not everyone can afford $ 1,200 for a 4 SIM card gateway. OpenVox sells for less than $ 500. And if we consider the modular giants at 8 -16 and more SIM cards, then there is generally the cost varies significantly.
A close competitor to GoIP - but I highly recommend not contacting devices from this manufacturer. Not only will you set it up for half a day, it will then constantly reboot, hang and keep you awake.
I tested the
VS-GW1200-4G for a couple of weeks in enhanced mode. "Not a single break!"
Colleagues, there is a full-fledged Asterisk in it, I won’t be surprised if you manage to set up IVR and queues on it and use it as a full-fledged PBX.

On this note, I propose to finish. Thank you for attention.
UPD: OpenVox VS-GW1200-4G discontinued. VS-GW1202-4G has been released, which allows expanding up to 8 SIM cards in the future.
