Redstone has been developing VoIP solutions for more than 17 years, and we have sold 10 million of gateway products to different customers including small and medium-sized business, large enterprises, and even government agents, banks and armies.

Why do they choose Redstone VoIP gateways? Maybe the following 6 reasons.

Flexibility
Redstone VoIP gateways are very flexible with various combinations of FXO and FXS ports (up to 96 ports). 

High Availability
All Redstone VoIP gateways are able to keep working under disaster for supporting features like power/network port redundancy, dual-system hot backup, PSTN failover, active standby and load balance.

Local Survivability 
In the case of a network disconnection, the Redstone survivability appliance takes control of the IP phones calls connecting them to the PSTN (if a connection to PSTN is available).

HTTPS FAX
Redstone ATA, which is bundled with FaxBack/NativeFax service, can create great value for easy to install/use, faster transmission and much lower cost for fax service.

Real Time Recording
Voice call recordings are sent in real time to an external storage server running a Redstone Call Recording Management System.
