If you’re worried about compatibility with your existing landline phones, make sure to read our guide to phones you can use with VoIP before taking a look at our collection of the best phone adapters. Magicjack Go has fewer added features than other ATAs, but one stand-out feature is its portability. Weighing only five ounces, its compact design allows you to tuck the Magicjack Go into your suitcase during international travel, so that you can continue to make and receive calls from home for free. Magicjack Go is the perfect choice for frequent travelers who want to stay connected back home. The easy-set up, convenient app and lack of any monthly fees are also nice features. With three-way voice conferencing also built in, the Grandstream adds enhanced features for an office environment, including support for T.38 faxing for IP as well as a range of caller ID formats to avoid picking up unwanted spam calls. Whereas some VoIP solutions connect to a Wi-Fi network, the Grandstream requires a direct connection via ethernet, which creates a more secure connection and stable calling performance. For long-term security, the Grandstream can be updated over the air to continuously fix security holes or bugs that are detected by the manufacturer. Home vs. business - Will you mainly be using your VoIP phone for personal or business use? This will play a factor in the type of phone adapter you need. If personal use is your main priority, you’ll likely only need one port. However, if you anticipate needing to make several calls or send faxes simultaneously, get an adapter with at least two ports. Other valuable features for a business phone include call forwarding/transfer and voicemail, so double-check that the adapter offers those as well. Sound quality - Sound quality is one area where a landline still exceeds that of a cell phone. You’ll notice the difference right away, making anything less sound like a call coming from the 1980s.
