Configure Additional Handsets For Calls

Once you've registered multiple handsets, you're able to select the accounts which they use for inbound and outbound calls.

"Outgoing lines" - select the line you'd like the handset to make calls from

Preventing "Ghost" Calls

Occasionally, if a phone isn't behind a firewall, potential hackers will try to access public phone systems by scanning IP addresses for a response. These scans cause IP Desk Phones to ring and calls would show a string of digits such as 100, 1000, 10000. These are referred to as "Ghost Calls".

To prevent these calls we recommend using a firewall, however, you're able to prevent these directly on the phone by setting the following.

📘

Under Features → General Information
"Allow IP Call" to 'Disabled'
"Accept SIP Trust Server Only" to Enabled

Changing Codecs

Our preferred codec to be used is PCMA.

📘

Under Account → Codec
"Enable Codecs" - 'PCMA'

Enabling RPort

TTNC VoIP Users require RPort to be enabled which can be done by setting the following.

📘

Under Account → Advanced
"RPort" to 'Enabled'

Network Transport Protocol

UDP is our preferred Transport Protocol as it's usually faster, simpler, and more efficient than TCP, however, in some scenarios, TCP may be the better Transport to use. This can be changed by updating the following:

📘

Under Account → SIP Server 1
"Transport" to 'UDP' or 'TCP'

Configuring Call Waiting

TTNC VoIP Users have 2 channels which can be used for inbound and outbound calls.

When you're on a call, you're able to see a second inbound call to the phone by enabling Call Waiting. Alternatively, if you don't want to be able to see that second call, you're able to disable this setting.

📘

Under Features → General Information
"Call Waiting" - 'Enabled' or 'Disabled'

Configuring Call Transfers

You're able to transfer calls to other VoIP User extensions or telephone numbers.

To enable Call Transfers, set the following:

📘

Under Features → Transfer

"Semi-Attended Transfer" to 'Enabled'
"Blind Transfer on Hook" to 'Enabled'
"Attended Transfer on Hook" to 'Enabled'

Updating Firmware

Yealink occasionally makes updates to the firmware for their phones. The latest versions and update notes can be found here: http://support.yealink.com/documentFront/forwardToDocumentFrontDisplayPage

Once you've downloaded the version of firmware you'd like to update to, do the following.

📘

Under Settings → Upgrade go to "Select and Upgrade Firmware" and 'Choose file'.
Browse to and select your firmware you would like to upgrade and click 'Open'.
Click the 'Upgrade' button.

Configuration Backup

You're able to back up the phone's configuration by exporting the config.

📘

Under Settings → Configuration:
"Export Import Config" - Choose 'Export'

Block out

If there are certain numbers or ranges you don't want your phone to dial out, block this by setting the following:

📘

This example will prevent the handset from being able to dial International Numbers.

Under Settings → Dial Plan → Block out.

"BlockOut Number1" to 00.
Please ensure the "." is included after the number.
"Account" to the 'Account' which you'd like to block this dialling.

You could also use this to prevent dialling a certain number range.

Factory Reset

If you have purchased a phone from an alternative provider, it may have an old configuration on it and may require a factory reset. You're able to do this through the phone in the following ways:

📘

Factory Reset Base

On the handset, press OK.

Select Settings → System Settings → Base Reset → Enter the current PIN → Reset to factory

📘

Factory Reset Handset

On the handset, press OK.

Select Settings → System Settings → Handset Reset → You will get a pop up that says 'Reset to factory setting'.

Select 'Yes'

Importing Contacts

Yealink DECT base stations support a local contact directory.

Deskphones generally support 100 local contacts.

Contacts can either be entered manually through the keypad using the phone's display, alternatively if you have a list of contacts, they can be imported through the phones web UI.
If you have multiple contacts you would like to import, using a CSV file is the most time-efficient method to do so.

Below you can find a sample contact file with the required headings in the first row, open this file in a spreadsheet application and begin adding your contacts on a new row.

Add a new row for each contact, you will need to add a minimum of a 'display_name' and a number in one of the relevant fields. e.g. 'office_number'

Keep the first row with the headings as-is, this will make the file easier to understand whilst you add your contacts. You can remove the headings when the file is imported.

In the above file we have added our Office Number as a contact on the second row.

🚧

Number Formatting (E.164)

Contact numbers entered will need to begin with '44'

Example: A number starting with 0203 becomes 44203

Once you have added your contacts - save the spreadsheet using a .csv file extension.

📘

Importing Contacts File

Under Directory → Local Directory → Browse (button)
Browse for your contacts file, select the file and click Open.
Click 'Import CSV' button.

The phones web UI should then show a list of contacts.

Tick 'The first line as the title'.

Choose 'Import' if the contact data is displaying as expected.
