When you have your VoIP User details, open the app and enter the information.
VoIP Username @
VoIP Domain / Outbound Proxy
Sign in, you will then have to agree to the Terms and Conditions, then you can set the Desktop App to be the default calling app. Clicking
Yes will give you instructions on how to make the TTNC app the default.
Once this is done, you can use the app to make and receive calls.
There are three main screens on the App, which are the Dialpad, Contacts and Recents.
For ease of navigation, all screens have the same sidebar.
Below the TTNC logo you have:
- Dialpad - This will show the keypad if it's hidden.
- Contacts - This will show the Contacts section below the keypad (or at the top of the window if the keypad is hidden).
- Recents - This will show the Recent Calls section.
- DND - You can toggle Do Not Disturb on and off.
- Settings - Opens a pop-up window showing the app's customisable settings.
The lowest icon shows the registration status of your VoIP User. A green dot means it's registered and working, and a red dot means that the registration has failed.
This screen allows the user to enter a number and make calls.
Opens below Dialpad - When a contact / quick dial is clicked, the information opens in an extended window giving all the details, including a green handset for making a call.
There are two views:
Quick Dial - Any other VoIP Users you have configured on the same number will automatically show here for internal calls. You can also add personal contacts to this list.
Address Book - This is currently only available on the Mac app and is your contact list from the native Mac Contacts app.
When you select a contact, their information will appear on the main screen to the right. Clicking on the green handset next to the number will initiate a call.
This displays all contacts and numbers for inbound and outbound calls that have taken place via the app.
Clicking on a name or number will open the extended window giving details of each call to and from the number.
In the bar at the top, you can see the number of the caller and their name if they're a contact, along with several buttons, from left to right, these are:
- Call - You can make a call to the number.
- Add Contact - You can add this number as a Quick Dial contact.
- History View - You can switch between viewing all calls, only inbound, only outbound, or all missed calls.
- Delete - This will delete all the call history for this number.
- Toggle Sidebar - This will hide or unhide the list of recent calls, as well as the Dialpad if it's enabled.
You can only receive calls if you have the TTNC Desktop Softphone open and you are logged in with your TTNC VoIP User.
Taking calls is as straightforward as receiving a call onto your mobile.
When a call comes in, a pop up will appear, and the ringtone will play. You can accept the call with the green handset button or reject the call with the red button. There is also the option to turn off the ringtone if you want the call to ring out.
Making calls is very straightforward and can be done in three ways:
- Via the Dialpad;
- From Call History;
- From Contacts.
Once an inbound or outbound call has been answered, the In-Call Screen will be displayed. This screen offers a range of services and information.
The labelled buttons on the in-call screen are:
- Toggle Call Recording on/off.
- Minimises the Dialpad, giving a full app window view of the in-call screen.
- Allows in-call sound source update.
- Opens and enables the Dialpad, allowing number entry from your keyboard.
- Put your caller on Hold - will change to a Play button while on hold.
- Terminate the call.
- Mute your microphone.
- Add Call - Start a new call - to enable 3-way calling.
- Attended Transfer - This allows you to speak to a colleague before transferring the call.
- Blind Transfer - This will cold transfer the call to a colleague without speaking to them first.
- Show the Mini In-Call screen.
Pressing the record button during a call will begin recording. You'll see the icon turn red and will hear an audible beep. Pressing the button again will stop the recording.
Once the call has completed, the call details and the recording will be available to listen to on the Recents screen.
Pressing the hold button during an inbound or outbound call will place the call on hold. The person on the other end of the call will hear hold music while the call is on hold. Pressing the button a second time will take the call off hold.
When you are on a call, you can transfer that call to another number. This can be done one of two ways, via an Attended Transfer or an Unattended Transfer.
The number to transfer to can be selected from the Contacts or Quickdial lists. Alternatively, a number can be typed into the Dialpad.
To do this, first, place your caller on hold, then click on the button for the type of transfer you would like. If you are using Attended Transfer, you can dial the number (or select the contact) of a colleague, and once you've given them the information, you can press the Transfer button highlighted with the white border.
If you're using Blind Transfer, as soon as the call to the destination you're transferring to is initiated, the transfer occurs - If you wish to cancel the transfer, you can press the cancel button to restart your conversation with the caller.
If you wish to bring a third person into the conversation click the Add Call button then enter the number you wish to call (you can also select the number from your contacts or recent).
Once the call connects you can merge the calls together.
When the calls merge, the app will show the participants and also that there is a conference call taking place.
If you wish to split the calls back out, you can click split, then choose which of the two calls to be enabled. The other call will be placed on hold. If you terminate a call with another call on hold, the second caller will be taken off hold automatically.
Rather than taking up a large part of your screen while on a call, you can show the Mini In-Call Screen. This screen has fewer options than the bigger In-Call screen, but you can alter sound settings, mute your mic and terminate the call.
The crossed arrows in the top right corner will show the full In-Call Screen.
To access the settings, click on the cog icon in the left sidebar. This will display the Settings pop-up window.
This shows information about the application and the version installed.
This shows details of the VoIP User registered to the app; it's not recommended to make any changes.
You can change your ringtone on this screen.
The Texttone option is currently unused.
This screen displays your available sound sources and volume settings.
- Speaker - the source of the audio when on a call.
- Microphone - the source of the mic when on a call.
- Ringtone audio output - the source which will play the ringtone when an inbound call reaches the app - this can be a different source to the speaker, meaning that you can have a headset for your calls, but use the computer's speakers for the ringtone.
- Noise suppression - reduces the amount of external noise from your mic.
- Playback boost - adds/removes volume from the app.
- Ringtone volume - change the volume of the Ringtone.
- Microphone level - change the output volume of your mic.
- Keypad volume - change the volume of the keypress on the keypad.
- Echo cancellation - will filter out some of the echo, if needed.
You can enable Call Recording for all calls and set the length of time that the audio is kept.
You can enable the app to automatically launch when you start your computer. You can also set the app as the default app for calls.
This screen displays all activity on the VoIP User account. This can be downloaded as a .txt file and may be used by TTNC Support for troubleshooting.
You can reset the app to remove your VoIP User information. You will need to log into the app again to make and receive calls.
The TTNC Desktop Softphone allows you to click on any phone number on a website which has been set up as a 'tel:' link. The number will look similar to a normal hyperlink on a website.
This is our main website.
The Telephone number link looks like this:
When a link is clicked, the TTNC Desktop Softphone will open and the number will be dialled. The first time this process is attempted the browser will ask for permission to open the TTNC Softphone. If access is denied the call cannot be made.
