Even when set up correctly, it’s common for VoIP phones to give users issues. These can be bewildering to those unfamiliar with VoIP and how it works, but telltale signs and symptoms usually make diagnosing your VoIP issues fairly simple. From there, you can begin working towards a resolution and the productivity that drew you to VoIP in the first place.

SIP ALG, cable configuration, assumptions about PoE, wireless signal strength and delinquent devices are some of the culprits of VoIP phone issues.

If your VoIP phone continues to ring after you’ve picked up the phone, if your VoIP phone won’t register with your VoIP provider, or if you can hear the other side, but they can’t hear you, you’ll want to turn off the SIP ALG setting in your router’s GUI. You can access this by entering your router’s IP address (usually listed with the password on the bottom of the router) into the address bar of your browser. If you’re unsure of where the SIP ALG setting might be, search online for ‘SIP ALG [your router model here]’.

If the VoIP phone is not powering on and you can’t figure out why you’ll want to check that your VoIP phone is receiving power. Are you using the correct power supply? If you’re trying to power the phone through PoE, do you have your PoE switch or injector configured correctly?

If the VoIP phone is not ringing, cannot receive or make calls, or if it is failing to establish a network connection, there are a number of things to try.

First, check that the cables are plugged in correctly on the back of the VoIP phone. The handset should be plugged into the handset port (not the ‘headset’ port). The ethernet cable should be plugged into the LAN or ‘internet’ port on the back of the phone (labelling varies by device).

Once you’ve confirmed that the device is correctly wired, try plugging the ethernet cable directly into your router at the other end. This confirms that it’s not a weak WiFi signal that’s causing your issues and also that there is no network device between your phone and the router that is disturbing the connection, which can also give you poor or crackly audio.
