Frequently Asked Questions

Why is my Snom D815 not registering with my VoIP provider?

First, verify that the SIP credentials (username, password, and domain) are entered correctly in the phone's account settings. Also check that the phone is connected to the network and has obtained a valid IP address. If the issue persists, confirm that your network firewall or router is not blocking SIP traffic on the required ports (usually 5060 for UDP/TCP).

The phone won't power on. What should I check?

Ensure the phone is receiving power. If you are using PoE, confirm that the Ethernet cable is connected to a PoE-enabled switch port and that the cable is not damaged. If using an AC adapter, verify that it is the correct voltage and is firmly plugged into the phone and a working outlet. Try a different Ethernet cable or power source to isolate the issue.

I can't hear any audio during calls. How do I fix this?

Start by checking the volume settings on the phone and ensure the handset or headset is securely connected. If using a headset, verify that the headset type is correctly configured in the phone's audio settings. Also, test with a different handset or headset to rule out a hardware fault.

The display is blank or flickering. What could be wrong?

First, check that the phone is powered on and the backlight settings are not set to a very low level. If the display remains blank, try a power cycle by disconnecting the Ethernet cable and any power adapter for 30 seconds, then reconnecting. If the issue continues, the display may have a hardware defect, and you should contact support.

How do I set up the WLAN on my Snom D815?

Navigate to the phone's Settings menu, select Network, then choose WLAN. Scan for available networks, select your SSID, and enter the Wi-Fi password. Ensure your wireless network uses WPA2 encryption for compatibility. Note that for best call quality, a wired Ethernet connection is recommended over Wi-Fi.

The phone keeps dropping calls. What should I try?

First, check your network connection: if using Wi-Fi, try switching to a wired Ethernet connection to rule out wireless interference. Also, verify that your internet connection is stable and has sufficient bandwidth. If the issue persists, try reducing the audio codec to G.711 in the phone's settings, as it uses less bandwidth.

My Snom D815 is not detecting the expansion module. What do I do?

Ensure the expansion module is properly connected to the phone via the dedicated port on the side of the D815. Power cycle both the phone and the expansion module by disconnecting them from power for 30 seconds. If it still isn't detected, check that the expansion module is compatible with the D815 and that the phone's firmware is up to date.

How do I transfer a call to another extension?

During an active call, press the Transfer key on the phone. Dial the number of the extension you want to transfer to. When you hear ringing or the recipient answers, press Transfer again to complete the transfer. For a blind transfer, press Transfer, dial the number, and then hang up without waiting for an answer.

The LED keys are not lighting up correctly. How can I fix this?

First, check the key assignment in the phone's settings under Function Keys. Ensure each key is programmed with a valid function or line. If the LEDs still behave incorrectly, try a soft reset by navigating to Settings > Maintenance > Restart. If the issue persists, the keys may need to be recalibrated or replaced.

Can I use the Snom D815 with a Canadian VoIP carrier like Bell or Rogers?

Yes, the Snom D815 is interoperable with all major IP PBX platforms and should work with Canadian carriers that provide SIP trunking. You will need to configure the SIP account settings provided by your carrier. For specific settings, consult your carrier's documentation or contact their support for guidance.

About This Product

The Snom D815 is a mid-range executive desk phone designed for professional office environments where a larger display and programmable keys improve workflow. Its 5-inch color screen and ten self-labeling multicolor LED keys make it suitable for users who handle multiple lines, such as receptionists, managers, or power users in a busy office. The phone pairs well with the optional D8C expansion module for even more line appearances, and its built-in WLAN and dual USB ports offer flexibility for wireless connectivity and peripheral storage. However, note that the power supply is sold separately, so you will need to either use Power over Ethernet (PoE) from a compatible switch or purchase an AC adapter. While the D815 supports twelve SIP accounts and works with all major IP PBX platforms, it may be overkill for a single-line home office user who would be better served by a simpler, lower-cost model. In a Canadian context, this phone is a solid choice for GTA office deployments where multi-line handling and headset integration via EHS are important, and it is compatible with most Canadian VoIP carriers.
