We tried several SIP Trunk providers and finally chose FS, the device worked as described, I really appreciate the excellent 24 x7 customer and technical support from FS.

The VoIP gateway includes one software selectable T1/E1/PRI interface and supports up to 30 concurrent calls and works great. It's excellent for my small business. Would buy from FS again.

Worked as expected. Its robust feature set includes the ability to configure call rules for connecting many combinations of telephony providers (traditional and VoIP) and PBXs (legacy and VoIP), failover routing to ensure calls won’t fail, licensing for the 30 numbers of calls the appliance supports, SIP to SIP transcoding and a proven design of no moving parts to meet communication needs in my company perfectly. I would buy it again if needed!

Excellent Device! The WEB/GUI Interface is always clear to help me configure smoothly. After tinkering with the product for about 30 minutes was able to setup the device to receive and place calls on my IP PBX bought from FS.

Worked the first try. Clean web interface for setup. Voice calls are clear with default settings, with no echo.
