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
Netgear R8000 Nighthawk X6 Tri-Band WiFi Router (AC3200)
Based on customer feedback and experience we know the above routers work well. As part of our award-winning open systems initiative, our phones will work with a wide variety of other routers, as well. If you are in a position to choose, however, we know these will work for you based on the success of other clients.
