Your hosted phone: web portal, Linkus and everyday calls
How to sign in, pair your phone with a QR code, and use hold, transfer, park and the rest of your National Phone & Data hosted phone system.
What you have, and what each piece is for
National Phone & Data hosts a Yeastar P-Series phone system for your business. You do not log in to the administrator console for day-to-day use. Your workplace is the Linkus user portal (web, desktop and mobile).
Linkus Web Client
The browser user portal. Make and take calls, set presence, listen to voicemail, and generate the QR used to pair Linkus on your phone. Use Chrome, Microsoft Edge or Opera.
Linkus Mobile Client
The iPhone and Android app. Your office extension in your pocket, using Wi-Fi or mobile data. Customers see your work number, not your personal mobile.
Linkus Desktop Client
The Windows and Mac app. Same features as the web portal, plus headset integration and optional control of your desk phone (CTI).
After your extension is created you receive a Linkus welcome email with a one-time QR code (mobile) and one-time login links (web and desktop). Keep the portal address we give you. You will need it after the first sign-in.
Linkus and the web portal use your user password. The SIP / phone registration password is a separate secret used only by desk phones. Do not share either. If someone asks you to read out a SIP password, stop and call us.
Sign in and find your way around
Do this on a computer first. The portal is where you change your password and pair the Linkus app.
First sign-in from the welcome email
-
1
Open the welcome email Find the Linkus welcome message. If it is missing, check junk. Ask your office admin or NPD to resend it if needed.
-
2
Click the Web Client link Use the public network (remote) link when you are off-site. Use the local network link only if you are on the office LAN and we have told you to.
-
3
Allow notifications When the browser asks, click Allow. Incoming calls show as a browser notification if the tab is in the background.
-
4
Accept the privacy agreement Tick the agreement and confirm. This appears on first login only.
-
5
Set a new password Choose a strong password you do not use elsewhere. Confirm it and save. From then on, sign in with your extension number or work email plus this new password.
-
6
Bookmark the address Copy the address in the browser bar. The one-time email link will not work again.
Your hosted phone is ready
Scan the QR code in Linkus Mobile, or use a one-time link below.
Open your bookmarked portal address. Username is your extension number or the email bound to your extension (we enable one or both). Password is the one you set on first login.
What you see after login
| Left menu | What you use it for |
|---|---|
| Extensions | See who is free, busy or away. Click a colleague to call or leave voicemail. |
| Contacts | Company directory and your personal contacts. Click to dial. |
| Chat | Internal messages with colleagues. External chat (SMS, WhatsApp and similar) appears only if we have enabled it for your site. |
| Operator Panel / Call Centre | Reception and queue tools. Only shown if we have granted you that role. |
| Call Logs | Your inbound, outbound and missed calls. Call back, add notes, or save a contact. |
| Voicemails | Play, transcribe (if enabled), download, forward or delete messages. |
| Recordings | Your call recordings, when recording is permitted for your extension. |
| Preferences | Profile, presence and forwarding, voicemail greeting, audio devices, function keys, email alerts. |
Toolbar (top of the portal)
Download clients
Icons for Linkus Desktop, Linkus Mobile and the Chrome extension. The Mobile icon shows store QR codes so you can install the app.
Presence
Available, Away, Do Not Disturb, Lunch Break, Business Trip, Off Work. Each status can have its own forwarding rules.
Web Client or CTI
Web Client uses your computer microphone and speaker. CTI lets the portal control your desk phone, desktop app or mobile instead.
On the login page click Forgot Password?, enter your extension number and the email bound to that extension, then use the reset link (valid 30 minutes, once only). If no email is bound, call us and we will reset it.
Install Linkus and scan the QR code
Two different QR codes exist. One installs the app. The other signs you in. Use them in that order.
QR 1: install the app
In the web portal toolbar click Download Linkus Mobile Client. Scan that QR with your phone camera to open the App Store or Google Play. You can also install directly:
Official app name: Yeastar Linkus Mobile Client. Do not install look-alike apps.
QR 2: sign in (one-time)
The login QR is in your welcome email. It is encrypted, works once, and then expires. After that, sign in with your username and the password you set on the web portal.
Need a fresh QR? Ask your office admin or NPD to send a new welcome email, or to copy a new Login QR Code from your extension.
Scan the login QR on your phone
-
1
Open Yeastar Linkus Mobile Client Do not use the phone camera as a generic QR scanner for login. The Linkus login screen has its own scanner.
-
2
Tap the QR icon Top-right of the Linkus login page. Allow camera access if asked.
-
3
Scan the QR in the welcome email Open the email on another device (computer or tablet) so the phone can see the code. Linkus reads the server details and signs you in.
-
4
First-time prompts Accept the privacy agreement and change the initial password if you have not already done so on the web. Then sign in again with the new password.
-
5
Allow microphone, notifications and (on iPhone) Background App Refresh Without notifications, incoming calls may not wake the phone. On Android, disable battery optimisation for Linkus if calls are missed when the screen is off.
Other ways to sign in
| Method | When to use it | How |
|---|---|---|
| Login link | Welcome email, or a link we send you. One-time. | Copy the mobile or desktop link on the phone or PC, then open it. Linkus fills the server details. |
| Domain + password | Everyday sign-in after the QR is used. | Username (extension or email), user password, and the domain or FQDN we gave you. No port needed when we use Remote Access / FQDN. |
| IP address + port | Only if we have given you a public IP and Linkus port (default local port is 8111). | Enter local IP and port for on-site use, plus public IP/host and external port if you work off-site. |
Desktop client and Chrome
-
1
Download Linkus Desktop From the web portal toolbar, or from yeastar.com/linkus-download. Windows 10 or later, or macOS 10.11 or later.
-
2
Sign in Use the desktop login link in the welcome email, or enter domain, username and password.
-
3
Optional: Yeastar Linkus for Google Chrome extension for click-to-dial on web pages and call notifications when the browser is closed. It still needs you signed in on Web or Desktop Client.
You can stay signed in on web, desktop, mobile and a desk phone together. Use Preferences (or the presence page) to set which device rings first. To review devices: account menu (top right) > Currently Logged-in Devices. You can add a remark or remotely sign a lost phone out.
Make, answer and send a call to voicemail
The same idea on web, desktop and mobile: keypad, contacts, or click a colleague.
Place a call
- Open the keypad (toolbar or Calls tab) and dial, then press the call button or Enter.
- On Extensions or Contacts, click the handset icon.
- From Call Logs, Voicemails or Recordings, click to call back.
Answer or decline
- Green / Answer accepts the call.
- Red / Decline rejects it. The caller then follows your No Answer or Busy rule (often voicemail).
- On web, allow the microphone when the browser asks.
Send this call to voicemail
- On the incoming pop-up, use Send to Voicemail (voicemail icon) instead of answering.
- Needs voicemail enabled on your extension. Ring-group and queue calls need that option turned on for the group.
If several company numbers are assigned to you, choose the outbound caller ID from the drop-down beside the keypad, or pick Select DOD to Call on a contact. A default DOD can also be set under Preferences > User.
Hold: pause the conversation on your device
Hold keeps the caller with you. Only you resume it, on the same client. Use Park if someone else must take the call.
-
1
Place on hold During the call, tap or click Hold. The other party cannot hear you. They may hear hold music, depending on system settings. On web and desktop you can hold up to six calls at once.
-
2
Resume Tap or click Hold again (or Resume) on that call. You are talking again.
A held call stays on your device. Walking to another room and dialling from a different phone will not pick it up. For that, park the call and dial the parking number.
Transfer: send the caller to someone else
Use attended transfer when you need to announce the caller. Use blind transfer when you just need them gone to the right place.
Blind transfer
The caller is sent immediately. You do not speak to the destination first.
-
1
Transfer > Blind Transfer On mobile the button is often labelled Blind. The caller is placed on hold.
-
2
Choose the destination Pick a colleague from the list, search by name, or type a number on the keypad.
-
3
You drop off Your leg ends. When they answer, they are talking to the original caller.
Attended transfer
You speak to the colleague first, then complete the hand-off.
-
1
Transfer > Attended Transfer On mobile this is often labelled Attended. The original caller is on hold.
-
2
Call the colleague Select them from the directory, search, or dial. They ring. You explain who is waiting.
-
3
Complete If they will take it, click or tap Transfer. You leave. The two parties are connected. If they cannot take it, hang up that second call and resume the original caller.
During a call, attended transfer is *3 then the extension (example *31002). Blind transfer is *03 then the extension (example *031002). Your handset may also have dedicated Transfer / Blind keys. Codes can be changed on your system; ask us if a code does nothing.
Park: leave the caller in a numbered slot
Park is the right tool when the caller must be picked up at another desk, or by whoever is free.
System Park
The system picks the next free slot. Good when you will retrieve it yourself on another phone, or you will shout the number to a colleague.
-
1
More > Park > System Park On mobile: Park then System Park.
-
2
Read the toast Example: “The call has been parked at 6000.” Write it down or tell the colleague.
-
3
Retrieve From any signed-in Linkus client or desk phone, dial that parking number (6000 in the example).
Selected park number
Park on a known slot, for example a department orbit. Anyone watching that slot can take the call.
-
1
More > Park > Selected Park Number The caller is held while available slots are listed.
-
2
Pick the slot Search or tap the number (example 6004 for Sales).
-
3
Retrieve Dial 6004, or press a Park & Retrieve function key that lights when that slot is busy.
If nobody retrieves the call, it usually rings back to the person who parked it, or goes to a destination we configured (another extension or voicemail). If you see “No available parking slot,” the call comes back to you immediately.
Park on the next free slot: dial *5 during the call. Park on a chosen slot: *05 plus the slot (example *056004). Retrieve by dialling the slot number.
Mute, record, flip, switch, merge and notes
Mute
Click or tap Mute so the other party cannot hear you. Tap again to unmute. Use this for a side conversation, not Hold (Hold plays music and pauses the call).
Record
If we have granted recording permission, tap Record. A recording indicator appears. Both sides may hear an announcement. Play files later under Recordings. During a call you can also dial *1 to start, pause or resume (permission required).
Call Flip
Move the live call to another of your devices without the caller noticing. Tap Call Flip, choose desk phone, desktop or mobile, then answer there. Default code: *01.
Call Switch
The opposite of Flip: pull a call that is already up on another of your devices onto this one. On web, click Call Switch at the top. On mobile, tap Touch here to start call switch.
Merge / conference
With two or more voice calls, click Merge Calls to make a three-way conference. You are the host. Invite more people from the conference controls if your plan allows it (desktop conferences support up to nine members).
Call notes
If we have enabled disposition codes, tap Call Notes, pick a code, add a remark, save. The next person who takes a transferred call can see the last note. Edit notes later in Call Logs.
Open the keypad to send tones for IVRs, mailbox PINs and similar. Function keys can also send a stored DTMF string so you do not type it every time.
Presence, forwarding and which device rings
Colleagues see your status. Each status can forward differently for internal and external callers.
-
1
Change status now Top of the web or desktop portal, or on mobile: account > current presence. Pick a status. Related forwarding starts immediately.
-
2
Edit the rules Preferences > Presence (web/desktop) or the pencil beside a status on mobile. Add a note. Set Internal and External forwarding separately: Always, No Answer, or When Busy. DND only supports Always.
-
3
Ring strategy Choose which endpoint rings first and second: desk phone, Linkus Mobile, Desktop (softphone) or Web Client. Set ring timeout (5 to 300 seconds). Unanswered calls follow your No Answer destination.
-
4
Ring your mobile as well Under a status (not DND), enable simultaneous ring to your mobile number. If we use a dial prefix for outbound calls, we will tell you what to enter. Turn on Call Confirmation so a mobile voicemail cannot steal the call: press 1 to accept, # to decline.
-
5
Temporary status Choose Set Temporary Status, pick how long (duration or until a date/time), optional note. When the time ends, you return to the previous status.
-
6
Auto switch with office hours Preferences > Features > Time-conditional Presence Auto Switch. Example: Available in business hours, Lunch Break at lunch, Off Work after hours and on holidays. Priority is Holidays, then Break Hours, then Business Hours, then Outside Business Hours.
*91 Available *92 Away *93 Do Not Disturb *94 Lunch Break *95 Business Trip *96 Off Work
Voicemail, greetings and recordings
In the portal or app
- Open Voicemails. Filter by new or old, search by name or number.
- Play, mark read, download, delete, or forward to colleagues (your copy stays).
- Transcription appears when we have enabled it and credit remains.
- Changes sync across web, desktop and mobile.
From any phone
- Check your mailbox: *2 then your PIN and #.
- Check a specific mailbox: *2 plus the extension (example *21001).
- Leave someone a message without ringing them: *12 plus the extension (example *121002).
- In the mailbox, option 4 changes your voicemail PIN.
Preferences > Voicemail: upload a WAV/MP3 or record a greeting in the browser. You can keep several personal greetings and assign them to different presence statuses. Set voicemail language under Preferences > User.
Contacts, chat, keys, security
Contacts
Company contacts are shared. Personal contacts are yours. Favourite people for faster dialling. You can add a contact from a call log or recording (right-click on web).
Chat
One-to-one or group chat with colleagues. Mute a noisy room (right-click > Mute notifications). Notification switches live under Preferences > Features.
Function keys
Preferences > Function Keys. Monitor a colleague (BLF), pick up their ringing call, park and retrieve a slot, check voicemail, send DTMF, or speed-dial. Keys sync to Linkus and, where the phone allows, to your desk phone.
Two-factor authentication
Account > Change Password & Security. Use Google Authenticator, Microsoft Authenticator, FreeOTP or Authy (scan the QR), or email codes. 2FA then applies to web, desktop and mobile. If you lose the device, call us to turn 2FA off.
Audio, theme, language
Preferences > Audio and Video: pick microphone and speaker. Theme can follow the browser or stay light/dark. Language for the portal, emails, system prompts and voicemail prompts can differ.
Queues, pickup and intercom
These appear when we have put you in a queue, pickup group or similar.
| Task | In Linkus | Default code |
|---|---|---|
| Log in or out of one queue | Agent status control on the toolbar, or presence auto-switch | *7 plus queue number (example *76400) |
| Pause a queue | Agent pause reason | *07 plus queue number |
| All queues in / out | Agent controls | *77 / *077 |
| Pick up a colleague | BLF function key, or click a ringing extension if permitted | Group *4. Directed *04 plus extension |
| Intercom | Intercom action on the colleague, if enabled | *6 plus extension |
Feature code cheat sheet
These are Yeastar P-Series defaults. Your site may use different codes. If a code does nothing, ask us for your printed list. Do not share supervisor codes (listen, whisper, barge-in, force drop). Those only work if we granted the permission.
| What you want | Default code | Example |
|---|---|---|
| Attended transfer | *3 + number | *31002 |
| Blind transfer | *03 + number | *031002 |
| Park (next slot) | *5 | During the call, then read the slot the system announces |
| Park on a chosen slot | *05 + slot | *056004 |
| Retrieve a parked call | Dial the slot | 6004 |
| Call flip to your other device | *01 | Answer on the device that rings |
| Start / pause recording | *1 | Permission required |
| Check voicemail | *2 | Then PIN and # |
| Leave voicemail | *12 + extension | *121002 |
| Forward all on / off | *31 / *031 | *31 to your voicemail, or *311002 to 1002 |
| Forward when busy on / off | *32 / *032 | Same pattern as above |
| Forward no answer on / off | *33 / *033 | Same pattern as above |
| Group pickup | *4 | Picks the first ringing group member |
| Pickup a specific extension | *04 + extension | *041002 |
| Intercom | *6 + extension | *61002 |
| Ask “what is my extension?” | *97 | Useful on a hot-desk phone |
Fixes you can try, then call us
| Symptom | What to try |
|---|---|
| QR will not sign me in | It is single-use (and on some older systems valid about 24 hours). Ask for a new welcome email, or sign in with username, password and domain. |
| Welcome email never arrived | Junk folder, then ask us to resend. Confirm the email on the extension is correct. |
| Web portal: no ringing or no audio | Use Chrome, Edge or Opera. Allow microphone and notifications. Check the correct device under Preferences > Audio and Video. Confirm you are in Web Client mode, not CTI, if you want the browser to be the phone. |
| Mobile misses calls with the screen off | Notifications on, Background App Refresh on (iPhone), battery optimisation off for Linkus (Android), a working data or Wi-Fi path, and push notifications enabled on that presence. |
| Signed out everywhere | Password may have been changed, or someone used Currently Logged-in Devices to sign you out. Sign in again. If it was not you, change the password and call us. |
| Account locked | Too many failed passwords lock the source IP for a period. Wait, use another network, or call us to clear the lockout. |
| Parked call came back | Timeout (default one minute). Park again and retrieve sooner, or ask us to extend the timeout for your site. |
Have your company name, extension number, whether you are on web, desktop, mobile or a desk phone, and what you saw on screen. Call (02) 8228 7777 or use the contact form.
