GSM gateway with Voice and SMS features based on OS Linux
GSM gateway G8 is a universal hardware platform for lowering calls costs and termination.
|Multifunctional GSM gateway for 4 SIM-cards for connection GSM and VoIP networks. Usually it serves for calls routing between desk phones and mobile networks (GSM) as well as receiving/sending SMS, sending USSD-requests. Most of all an integration of the VoIP-GSM gateway into the corporate telephone network facilitates saving on costs of «office — mobile phone» calls. By the means of GSM-gateway it is easy to create telephony at locations where PSTN telephony is unavailable.
The chassis of GSM Gateway G8 has 1 universal slot for extension board (GSM, 3G/GSM). Due to this the model allows scaling of GSM-channels (SIM-cards) number from 4 to 8.
Especially relevant to the creation of office IP-PBX the fact that there is an IP-PBX Asterisk v1. 6 preinstalled on the GSM-gateway. Therefore the device operates under OS Linux 2.6 (for Atom CPU). Gateways are compatible with SIM-Server/SIM-bank solutions, reliable and straightforward in operation. The gateway design assumes desktop placement. There are also special openings in the housing for wall mounting. The GSM gateway supports SIP-protocol completely. As a result the equipment is compatible with IP PBX’es like Asterisk, 3CX, Oktell, Askozia, Elastix, Lynx, Cisco Call-Manager, Kerio Operator, etc.
Application and benefits
|Gateway between cell networks and IP-PBX. Provides saving on outgoing GSM-calls rather then paying high costs for landline-to-GSM calls. At the same time it makes your clients pay less for calling your numbers.
Individual and Bulk SMS. In addition to calls – SMS is modern and universal media channel.
Call termination/origination. Establishing of GSM-gateways distributed network by the means of the SIM-server in almost no time.
Embedded IP-PBX Asterisk, embedded SMS-server. Scalability and openness for adding custom Linux-software.
Free technical support – 1 year. Warranty – 2 years.
|Quick-start – ready for operation out of the box same like regular WiFi-router.
Support of all main telephony and SMS protocols. Due to open architecture more protocols can be added on request.
Scalability (increasing GSM-channels quantity) by extension boards opposite to buying new device.
OS Linux – open system for fine-tuning by specialist. Consequently you less dependent on specialized support.
High traffic capacity – 600 minutes per day and more, per channel. Opposite to cheapest USB-gateways it does not freeze on 24/7.
Closed channel mode — placing call via specific GSM-module. Especially useful for integration with external PBX dial plan.
Lowering base stations load – option to turn off unused GSM-modules individually.
System management and monitoring via Web GUI, console or SSH. The SSH is probably most useful for OS setup and Asterisk tuning.
Detailed CDR – gateway automatically stores detailed information about calls into a file in addition to WEB GUI.
Detailed cause codes (disconnect codes) of a mobile network – useful feature for predictive dialers
Gateway is ready to act as a standalone PBX thanks to pre-installed popular free IP-PBX Asterisk. Opposite to WEB GUI the Asterisk CLI and config files provide most powerful tools for telephony setup.
Incoming call routing — thanks to an intellectual processing of incoming calls based on Caller ID. The call may be forwarded to previously defined route. Most noteworthy this can be used for instant creating of GSM DID-numbers.
Integrated LAN and WAN ports — it is possible to use either public or private IP-addresses.
VPN-client – client for VPN-networks is pre-installed. The same you can achieve by using external VPN-adapter (like MikroTik).
Comfortable way to reach the office staff for clients and workers. Rather than calling landline office numbers, dial any SIM-card in gateway followed by extension number.
Redundant voice channels for office hence it stays reachable even if landlines fault.
|Callback feature — additional money saving feature for cell phone calls. In addition to this feature, it also can be achieved with on-board Asterisk.
Hence the easiest way of quick installation of telephones for remote office or shop, where fixed lines are unavailable or costly.
Outgoing call routing based on lowest cost (Least Cost Routing) so it routes outgoing calls by best (cheapest) cost. Opposite to prefix based routing – it routes calls by cost.
As a result of prefix based call routing – cutting costs for calls from office to mobile phones.
Cutting calls cost when travelling abroad. Especially relevant if you have Internet available when travelling.
