Recommended Routers


While we’ll make sure your phone calls go through our system correctly, you’ll want to make sure your network can support VoIP traffic and keep your network within needed limits for jitter, latency, and packet loss.

Southwest Telephone Company supports industry-standard Session Initiation Protocol (SIP) for communication with VoIP phones. We have no specialized requirements and no proprietary communication needs. In addition, phones purchased from Southwest are pre-configured, or “plug and play”. Most of our clients simply plug phones into their Internet connection and they work instantly.

If you do have trouble with your network, the problem may be with your choice of network router. We’ve found some routers work better with SIP traffic and VoIP calls than others. A list of our recommended routers is shown below.

Apple Airport Extreme

Ultrafast 802.11ac Wi-Fi. With 802.11ac technology and a powerful beamforming antenna array, AirPort Extreme gives you up to 3x faster Wi-Fi and a stronger, clearer signal. And because it transmits at both the 2.4GHz and 5GHz frequencies at the same time, your wireless devices will automatically connect to the best available band for the fastest performance possible. Designed with performance in mind. With the antennas at the top of the elevated design, AirPort Extreme now has a higher platform for dispersing the signal. Apple also increased the number of antennas. There are now six of them — three for the 2.4GHz band and three for the 5GHz band. Together with 802.11ac technology, they let you connect faster, farther, and with more power than ever before. Easy setup for iOS and OS X. Connect your DSL or cable modem to AirPort Extreme and use the built-in setup assistant to create your new wireless network in just a few taps from your iPhone, iPad, or iPod touch. If you’re using a Mac, use the built-in AirPort Utility. Setup is just as fast and just as easy. This router is the best choice for people who want complete ease of use and 100% compatibility out of the box. It does not support QOS. Features and specs can be found on Apple’s website.

Netgear R8000 Nighthawk X6 Tri-Band WiFi Router (AC3200)

802.11ac Tri-Band Gigabit Wi-Fi Router. The Nighthawk X6 AC3200 Router with breakthrough Tri-Band WiFi technology was built to connect to each and every device in your home—automatically and simultaneously. Laptops, tablets, phones, TVs, game consoles, music streamers, cameras – if it’s WiFi enabled, it’s X6 accelerated. A powerful combination of features —wireless speed of up to 3.2Gbps, 3 WiFi bands, Smart Connect intelligence, and Dynamic QoS— guarantees every device is assigned the fastest WiFi connection possible and optimized for maximum speed. A product overview and technical specs can be found at Netgear.
