VUC User Guide

Version 1.0.1

Welcome to the Virtual Landlines VUC user guide. This user guide covers all the VUC features which can be viewed here. The below videos can be viewed and will provide you with a quick overview of the VUC Dashboard and features.

In the Virtual Landlines service,  email addresses are the users’ logins. The email given when creating a company account will become the admin user.

The admin has access to additional functions which are grouped under the Settings menu.

During the sign up you need to enter the total number of users. The number includes the admin account and accounts for your colleagues.  This limit can be changed later from the Settings/Account menu.

When you log in for the first time as the admin account your first task should be to create accounts for your colleagues.  To do so enough is to put their email addresses in the form on the initial screen. The platform will send each user create a welcome email with login details.


Adding phone numbers in this stage is optional. Each user can add his phone number himself after logging in to the portal and then to the My profile section.

Each user can modify his profile settings through the My profile menu. To get there click on the avatar in the left top corner and choose My profile from the menu.

The picture below shows the fields and setting options included in this menu.

On top of the screen is a set of buttons leading to certain features screens. They will be described in greater details in separate sections of this document.

Profile Details

A user can set his profile details seen by other users. To add a profile picture (avatar) click on the default picture and choose whether you want to use a camera or upload a previously stored file. A user can also add or modify his mobile number if he wishes to use this number as his caller ID when making calls from the Virtual Landlines platform.

Branch and extension numbers

Besides the profile details My profile includes the Branch and Extension numbers which are “read only” as they can be set only by the admin user.

Branch can be a department within the company or a physical location. It makes using the company directory easier. Also, using branches simplifies the internal numbering plans as explained in the Adding users section. If you do not want to use branches all users will be assigned to the “default” branch.

Extension numbers cannot be modified or added from the My profile menu. Only the admin can do it from the Settings/Users menu. Here a user can see his extensions.

Caller ID

Caller ID is the number shown to the called parties when calling offnet numbers.

A user can choose one of the numbers assigned to the company i.e. the default company line added during the signup process or a number purchased from the Settings\Accounts. Only the admin user can purchase phone numbers.

From the numbers assigned to the company the ones which can be used as caller ID by a user are those which are:

  • Explicitly mapped to the user in the Settings\Numbers menu
  • Mapped to a Voice Menu
  • Shared with other user using time routing

In addition, a user can set as caller ID his own mobile number under condition that the number has been verified.

Ringback Timeout

Ringback timeout is the time for which an incoming call can ring on your devices. When it elapses, the rules defined in Find me menu will be triggered. By default, incoming calls are directed to voicemail.

Click to call me

The click to call me feature creates a link which you can put on a website or include in your email signature as an easy way of contacting you either through a call or text.

Click on the pen icon to open the configuration panel.

Name – this is for you only to recognize calls coming from this particular “click to call” link. The calls will be shown as c2c_Name_(display_name), where display_name is the name entered by the caller when prompted after clicking the link.

My name shown to the caller – it is the name shown on the top of the page which open after clicking the click to call link.

Chat– this option enables chat on the click to call page.

To see what the click to call page looks like click on the arrow icon.

Click on the copy icon to get the link copied to your clipboard.

The company directory stores records of every user that belong to the company account. The list view in the sidebar shows the names of the users with their status texts.

You can use branches filter to see your colleagues from certain branch only.

There is also a search function which instantly filters the results.

Click on a row representing a user and the chat view will open on the right. This is the main panel showing all the past communication events in a form of conversation. More on the internal communication among users is explained in further chapters.

On the top bar you can see real-time presence status of the user.

Contact info

To see user profile, click on the profile or click on the menu icon on the right of the bar and choose Contact info.

The Last seen is shown when the user’s status is offline.

The offline/online statuses refer only to mobile apps and web portal and indicate when a user is logged in. Still you can call an offline user as the platform supports PUSH notifications and as long as he is connected to internet the call or chat will reach him.

Channels in common shows the list of channels shared by you and the user.

Starred messages group all the messages that you have marked as starred in this conversation.


his function disables sounds notifications for calls and messages sent by this user. If you check Mute in the portal the function will work on all your devices.

Contacts menu lets you browse the web phone book.

Both the web and mobile contacts are private – only the user created or uploaded them will see them.

You can choose which contacts you want to see by clicking the filter box under the Search field. The default option is All. You can expand it and you will see the Web contacts and list of your devices.


Web Contacts

You can add contacts through the portal. They will be available on the web.

Click on the plus button to add a new contact. To see contact details click on the menu on the right side of the top bar.

To start a call or to send an SMS click on the contact. The chat window will open on the right.

The Virtual Landlines application allows you to buy a phone number from any of 65 supported countries and more than 8000 cities.

During the signup one or more phone numbers are assigned to your account. You can then add more numbers directly from the portal. The process is fully automated. The moment you place an order the number is assigned to your company account and available to use on your setup panel.

Note: Certain countries requires special registration and supporting documentation will be required. Click here to view all countries with requirements.

By default, the numbers are routed to the admin user. You can configure inbound routing from the Settings\Numbers menu.

Adding a Number

Only company’s admin can order new numbers.

Buying numbers is not available with the Trial package.

To buy a number go to Settings\Numbers menu and click on the Add phone number.

Inbound Routing

If someone calls a newly added number it will ring on the admin device. To change the routing go to Settings\Numbers and find the entry representing given phone number.

If you want to select another user just click on the Route name list and select another user. There are also other route types that may be useful in your company.

Extensions are short three digits numbers plus two digits branch prefix. Within the same branch you do not need to dial the prefix. If you do not use branches all extensions are created in the default branch.

Extensions can be assigned to:

  • Users (it makes easier to dial manually from a device)
  • Call group
  • Extensions are shown in the Settings\Numbers menu.

When adding a new extension choose a branch of leave default if you do not use branches. Then define extension number – has to be unique within branch. Next choose the route type and select the route object.

The click to call feature enables communication directly from a web browser simply by clicking a link. It is another dimension of your business phone line. You can generate a link in VUC portal and place it on your website, associate it with a “call me” button or use in your email signature. Website visitors or email recipients do not have to sign in or download any additional software as the entire app is based on technology supported by browsers.

  • HD audio
  • Video
  • Instant messaging

When creating a click to call link you can decide what options should be allowed. You can let your customers chat with you or even have a video conference while browsing your website.

Both calls and chats will be received on your browser or even you can answer a call on your Yealink phone.

The answering rules will work too – if a c2c link is directed to a user his answering rules will be used like for any other incoming call.

Time spans

You can define exceptions using Time Spans and define when the inbound calls or chats should be diverted to other users or call group.

From Virtual Landlines you can call other users as well as phone numbers from other networks (mobile or landline). User to user calls are referred to as free, both in the portal and mobile apps.

  • Free onnet calls- limited to the company users, enabling greater capabilities
  • Paid offnet calls –calls and SMSs to external numbers.

Calls can be started from contacts, company directory or the recent history menu by clicking an icon representing voice call or video call.

Video icon is available only for the onnet calls.

User to user audio calling uses HD voice codec which is also dynamically adjusting to different network conditions.

The call button by default initiate onnet call. If you want to call external phone numbers hover mouse over the button and you will see the menu with the paid call option. You can also click on the avatar which will open the contact info panel with the list of all user’s phone numbers.

You can also make a call from the dialpad. To open it go to the Recents menu and click on the dialpad icon in the lower part of the list. The dialpad lets you enter a phone number and make a call or send SMS to it.

Encryption and media path

Calls made between users using our mobile apps or portal are fully encrypted using DTLS/SRTP.

The portal and the apps use the ICE mechanism for establishing media path. They always try to connect first in peer to peer mode, so the media – audio and video, are sent directly between users, without going to the server. If you are in the same local WIFI almost for sure the media path will stay within the network and thus the quality of the connection should be perfect.

Video Call

To start video call, click on the video icon next to the call button. The button is shown only for the onnet contacts.

While in the video call, you can click on the full screen icon.

An active call is shown in the left top corner, on the sidebar. Below the picture of the called contact there are call icons:

  • hold
  • video (enables video, available only for user to user calls)
  • transfer
  • end call


Transfer lets you send a connected call to another number – either onnet or offnet. The caller is put on hold while the call is being transferred.

Multiple Calls

The portal and mobile apps support two connected calls at the same time. While in a call you can initiate a new one. The first call will be put on hold, the second call will be active. Another case is that you receive second call during an active call. If you answer the first call will be put on hold.

The status of the calls – active or on hold, is shown on the top of the sidebar. Click on a call to switch between calls. The clicked call will become active and the other will be put on hold.

Three way calling (ad-hoc conference)

Two simultaneous calls can be merged into a conference by clicking the merge button. A new channel is created with the name “Conf call by username initiating the conference” with all three parties added as channel’s members.

The conference initiator and other onnet members will automatically connect to the channel’s audio bridge.

If a call is of offnet type it will be transferred to the bridge and will be shown in the channel as guest member.

Once the conference is created you can add other users or invite non-company users by email or send PIN for dial in access. More on the channel’s audio conferencing is described here.

Chat panel shows all the communication events with the contact. There are bubbles representing messages, calls, voicemails and attachments.

Messages exchanged among users are referred to as chats.

Messages sent to offnet numbers are referred to as SMS.

When you open a chat panel with a company user the default message type will be chat.

Offline History

All chats are stored on the server. The offline history is synced across all devices. Even if you receive a chat on for example portal it will be on your mobile app too.

Delivery and read confirmation

When a chat is received by the other user you will get a delivery confirmation which is represented by a double blue tick on the message bubble. One blue tick indicates only that the chat has been received by the Virtual Landlines cloud platform.

When a user open chat containing the received message, the sender will get read confirmation and the double ticks will change color to dark blue.

Chat’s delivery statuses:

  • Sent – one blue tick, message reached the platform
  • Delivered – two gray ticks, message reached the destination device
  • Read – two ticks change color to blue, the receiver opened chat window with the message


SMS can be sent to offnet phone numbers – from contacts or entered in the dialpad. To send an SMS to a user click on the link button left to the chat input box. It will let you choose between chat or SMS.

SMS shows caller ID in the same way as phone calls. Go to my profile menu to choose caller ID.

SMSs do not support delivery or read confirmation.

Typing notification

When you are chatting with another user you can see when he is writing a response. It is shown as a small pen icon just above the input text box in the chat panel.


Notifications are shown in two cases:

  • When the portal is open but you are on another tab or the browser is in background under another app which is in front.
  • When the portal is closed

In both cases the browser must be open.

Notifications are sent for the following events:

  • chat
  • channel message
  • incoming call
  • missed call
  • new voicemail

    • play greeting – choose a greeting to be played, if you choose to repeat scenario again you can play for example “No number was chosen, press 1 to connect…”
    • repeat scenario – define how many times the scenario can be processed, when this number is reached the scenario moves to the ending action
  • Ending action:
    • play greeting
    • and :
      • disconnect
      • dial menu number – you can choose which menu number will be dialed. For example, you may want the caller to be connected with default operator if no menu number pressed.
