Popular choices for VoIP ATA Adapters

      Rating  0     Rating  0

There are many VoIP provider that support BYOD (Bring Your Own Device) in which case gives the flexibility to the end user to supply their own ATA (Analog Telephone Adapter). This is a good option for those users that are technically savvy since can result in significant savings and a good way for providers to save on costs (typically support on foreign devices is reduced and there’s no shipping or complicated return RMAs involved)

There are many in the market but here we review some of the most commonly used and preferred choices

The newest of the adapters to become a type of cult. We like the OBi202 because it’s a fully ATA with support to two phone lines. Can be configured with any SIP services available and supports the most typical codecs used in VoIP. It has Two RJ-45 Ethernet and a USB port which could be used to connect a Wi-Fi adapter. The unit also has embedded QoS capability – which shall help improve maintain an optimum  voice quality throughout all calls.

Cisco has always produced very good network equipment, in the years gone by it used to be Linksys (owned by Cisco) who had tackled the VoIP ATA market better. but here of late seems there is a switch and Cisco’s own brand is producing very good and reliable products. The SPA112 is a very economical and reliable unit, supporting all codecs, typical features plus having fax (T.38) support. It has one RJ-45 Ethernet interface and also supports two phone lines.

The Grandstream is a great unit, used by many VoIP providers that supply their own ATAs. The HT-502 supports a wide variety of codecs, includes fax support. It has 2-phone lines and 2-network ports with a network router. It supports all the usual VoIP features, such as Do Not Disturb, Caller ID, 3-Way Calling and so on.

This GrandStream is a great little inexpensive  yet powerful unit. It comes with one network interface and one phone line; supporting all typical codecs and fax wtih the usual VoIP features. This unit is also preferred by VoIP providers.
When choosing an ATA make sure to check with the VoIP provider, as in many cases they do have a hardware compatibility list. Majority of our Top VoIP providers do support BYOD, but since you are not sure is better to ask and you can use these 4 ATA as a reference as being widely popular.
