Poor call quality can be a result of a weak WiFi signal. First, try moving your phone closer to your WiFi router to see if call quality improves. If that resolves the problem consider moving your modem closer to your phone to improve the signal strength or contact Blackfoot for a WiFi extender to improve WiFi coverage in your business. If moving closer to your WiFi router doesn’t resolve the issue connect your phone via the provided Ethernet cable to any active Ethernet port.
