Call quality or one-way audio issuesYour Granite Cloud Hosted VoIP phone uses your internet connection to make and receive calls. If your internet is experiencing trouble, your phone could have one-way audio or poor audio quality. Even if you do not see any internet issues on your computer, there could still be an issue with your internet provider or your on-site network equipment. Hosted VoIP phones require real-time delivery of the data traffic over the internet for a call to be clear, while computer traffic can retry several times in just a few seconds. When your internet is having an issue, phone call quality will suffer. Below are some tips to try before contacting support: Issue is isolated to a few phones: Reset phone – Unplug the AC power cord OR unplug the network cable from the phone. Phone’s display will go blank. Wait 10 seconds and plug the removed cord back in. Issue is occurring on all phones: Reset network equipment – reset the modem provided by your internet provider (Comcast, Cox, Optimum, etc.) as well as your firewall that connects to the modem. Issue is with a single phone: Does the issue only occur while using the handset? Does using speakerphone not have the issue? Check coil cord connection on back of phone to be sure it is in the handset port and not the headset port.
