Tiger Netcom GW0227 Telephone Adaptor

gw0227When taking a look at analog telephone adaptors one of my biggest pet peeves is the FXO port. I am a big proponent of service providers supporting and recommending telephone adaptors that have an FXO support. So, you can imagine that I was pleasantly surprised when I recently had the opportunity to demo the Tiger Netcom GW0227 analog telephone adaptor which features a single FXO port alongside a single FXS port.

GW0227 Telephone Adaptor Perfect for Residential Service Providers

This two port ata is designed specifically for users to take advantage of the FXO port, which performs intelligent routing. The FXO port can be used to make/receive calls to/from the PSTN from/to the phone attached to the FXS port, as well as bridge calls between VoIP and the PSTN. This gateway is ideal SOHO and small business users.I am constantly being asked by service providers to talk about the different options that exist for customer premise equipment, especially OEM or co-brandable units. For those of you with this request, the GW0227 from Tiger Netcom is exactly what you are looking for. With quantity discounts starting at just 100 units, and co-branding/pricate labeling starting at just 500 units the GW0227 is an excellent value.What surprised me the most about the unit was the excellent web GUI, unit construction, and robust feature set.

GW0227 Overall Impressions

This device has it all. With pricing for only 100 units at $49.99 it is definitely one of the lowest price devices on the market (I think they should raise the price!), but that should not deter you from purchasing these devices. As with all of Tiger Netcom’s devices, I was impressed by the overall quality, ease of use, configuration, and of course the feature sets.If you are a VoIP service provider in the market for a high quality, low cost ata, check out the GW0227 at
