Use a desk phone with Line

Owner, Admin

A desk phone can ring with your team and place calls on your Line number. The phone must be a SIP phone. Yealink, Poly, Grandstream and Cisco phones are SIP phones. An old analogue phone needs a SIP adapter first.

Before you start

  • You need the Owner or Admin role.
  • The phone must support SIP over TLS and SRTP.
  • The person who uses the phone must be a member of your workspace.

Add the desk phone

  1. Open Channels.
  2. Select Calls.
  3. Select Desk phones.
  4. In Name, type a name, for example "Reception".
  5. In Rings for, select the team member.
  6. Select Add desk phone.

Line shows the Server, Port, Username and Password. The password is shown one time. Copy it before you select Done.

Enter the settings in the phone

  1. Open the phone's web page or menu.
  2. Add a new SIP account.
  3. Type the Server in the registrar and the outbound proxy fields.
  4. Type the Port.
  5. Type the Username in the user name and authentication name fields.
  6. Type the Password.
  7. Set the transport to TLS.
  8. Turn on SRTP for media.
  9. Save. The phone registers.

Ring the desk phone

A desk phone rings as a device of its team member. Add a Ring Members/Groups step to the call workflow and select that member. The desk phone rings with their other devices.

To ring only the desk phone, set Ring devices to Desk phone only for that member.

The desk phone rings only while the member's status is Available.

Call out from the desk phone

Dial the number on the phone. The call goes out on your Line number and shows in the call log under the team member. Calls use credits in the same way as calls in the app.

What the desk phone shows

The desk phone shows your Line number, not the caller's number.

Change or remove a desk phone

  • To make a new password, select New password. The phone stops working until you enter the new password.
  • To remove the phone, select Remove. It stops working at once.

Common problems

The phone does not register. Check the server, username and password. Check that the transport is TLS and that SRTP is on.

The phone does not ring. The member's status is not Available, or the workflow does not select that member.

Line says it cannot connect an emergency call. Line cannot connect 999 or 112 from a desk phone. Use another phone.

Line refuses a number you dial. Line does not call premium-rate, personal or special-rate numbers from a desk phone. Calls to countries outside the UK need support to enable them. Contact support@useline.io.
