Provisioning additional handsets and extensions onto a Yealink base station

When adding a new handset to an existing base station via provisioning and pairing it to a new extension (SIP account), you can add the following information to the Device profile's Additional Configuration tab in the customer's phone system:

account.2.enable = 1
account.2.label = {{unit.name}}
account.2.display_name = extension-name
account.2.auth_name = extension-username
account.2.user_name = extension-username
account.2.password = extension-password
account.2.sip_server.1.address = {{unit.sip_hostname}}

The variables, denoted by the curly braces {{ & }}, can remain as they are as these will be automatically populated from the phone system and your partner profile. However, you must update the username, display name and password to match the extension you're adding to the device.

If you are provisioning more than accounts to the same base station, you'll need to update the account number from account.2 to account.3 or another number that relates the account you're setting up.

By default, the handsets will map to each SIP account on a one-by-one basis, meaning each extension will be assigned to each account in the order in that they are connected.

Mapping handsets to a single extension

If you need to map multiple handsets to one extension, you'll need to ensure the handsets are set to a specific SIP account on the base station for both outgoing and incoming calls. Add 3 lines to the Additional Configuration tab, ensuring they're modified as appropriate for the handset you're setting up.

handset.x.incoming_lines = 1
handset.x.name = Handset x
handset.x.dial_out_lines = 1

Replacing x with the handset number as appropriate.
