About the Snom L130

This guide covers the Snom L130, a VoIP desk phone listed as ENERGY STAR certified.

It connects to your network as a Voice over IP (VoIP) endpoint rather than to an analog phone line. It has one Gigabit Ethernet port. It can be powered over the network cable as a PoE Class 2 device.

Measured standby power is 1.3 W — about 11.4 kWh or $1.94 a year if it stays plugged in around the clock, as phones normally do. That is lower than 82% of the 85 VoIP Desk Phone models in our database.

Safety information

  • Use only the power adapter supplied with the phone or exact replacements from the manufacturer.
  • Do not use the phone near water — for example near a bathtub, sink or swimming pool — and never handle it with wet hands.
  • Avoid using any phone connected to outdoor wiring during a thunderstorm.
  • Do not use the phone to report a gas leak while you are near the leak. Leave the area first.
  • A VoIP phone works only when its network, power source (PoE switch or adapter) and phone service are up. Keep an alternative way to call 911 during outages.

Setup

  1. Connect to the network

    Connect the phone's LAN port to a network switch port with an Ethernet cable. If the switch provides PoE, the phone powers up from the cable. As a Class 2 device it can draw up to about 6.49 W, so budget at least that much per port on the switch. Where PoE is not available, use the manufacturer's AC adapter instead.

  2. Provision the phone

    Most business VoIP phones are configured automatically from the phone system or by your administrator. For manual setup, enter the SIP account, server and credentials from your service provider in the phone's web interface.

Using your phone

Calls and audio

  • Adjust the earpiece or speaker volume during a call with the volume keys; the setting is usually remembered for the next call.
  • Call quality on VoIP depends on the network. If voices break up, ask your administrator to prioritize voice traffic (QoS) or use a wired connection.

Power use

Phones stay powered all the time, so standby power is what matters. This model draws 1.3 W when idle. On PoE, the switch supplies this power, and switch conversion losses add slightly to the total.

Care and maintenance

WhenWhat to do
WeeklyWipe the handset, keypad and display with a soft cloth lightly dampened with water or a mild disinfectant wipe; do not spray liquids directly on the phone or use solvents.
Every 6 monthsCheck cords and plugs for damage, and confirm the phone is running the firmware version your administrator or provider recommends.

Troubleshooting

Try these steps before calling for service. For model-specific error messages, consult the manufacturer's manual or your phone system administrator.

ProblemPossible causeWhat to try
Phone does not power onSwitch port not providing PoE or insufficient power budget; damaged cable.Try another PoE port or a known-good cable, and confirm the switch can supply Class 2 power; otherwise use the AC adapter if available.
"No service" or registration failedNetwork or VLAN settings; provisioning error; account not active.Restart the phone, confirm it obtains an IP address, and ask your administrator or provider to verify the account and provisioning.
Choppy audio, echo or one-way audioNetwork congestion; firewall/NAT settings; Wi-Fi interference.Use a wired connection, enable QoS for voice, and have the administrator check firewall SIP and RTP settings.
Display or keys unresponsiveTemporary software fault.Restart the phone by unplugging and reconnecting the network cable.

Energy use and running costs

The Snom L130 draws 1.3 W in standby — the idle state it spends nearly all of its time in, connected to the network but not on a call. Plugged in 24 hours a day, 365 days a year, that is about 11.4 kWh per year, or $1.94 at $0.17 per kWh.

As a PoE Class 2 device, the phone can draw up to 6.49 W at peak (for example with the backlight on or during a call on speaker), though typical idle draw is the 1.3 W measured above. The switch's own losses come on top of this.

Talk time adds very little energy compared with standby, because calls are short relative to the hours the phone sits idle.

Frequently asked questions

What kind of phone is the Snom L130?

It is a VoIP desk phone, listed in ENERGY STAR's corded configuration.

How much electricity does the Snom L130 use?

It draws 1.3 W in standby, about 11.4 kWh per year — roughly $1.94 at $0.17/kWh if left on continuously.

Can the Snom L130 be powered over Ethernet?

Yes. It is a PoE Class 2 device, so an IEEE 802.3af/at switch or injector can power it over the network cable.

Will the Snom L130 work during a power outage?

Only if the network equipment and PoE switch are on backup power and your phone service is up. Keep another way to call 911.

How many Ethernet ports does the Snom L130 have?

It has one Gigabit Ethernet port.
