1. Setup
Download Impact Phone for Windows using this link: https://cdn.impactechs.com/telecoms/ImpactPhone/ImpactPhone-1.0.13-rc2.exe
Please install Impact Phone on your Windows machine using the setup file provided. To do this you will need Administrator privileges.
After installing you will see the screen pictured above. If using the Impact CRM login with the same account credentials using your email address, host name and password. If not, select “Impact PBX LOG in”.
After selecting “Impact PBX LOG in”, the screen above appears. Enter the data received from your admin regarding your extension. Create a display name for each extension in the Impact Phone, so you can easily distinguish between them. The API key is only necessary if you want to see your remaining account balance in Impact Trunk (if configured) and your colleagues' extensions in "Company Extensions". Your admin will supply the API Key, if needed. Click “Connect” to continue.
You should now be connected. The green dot next to the user name signals successful connection. If the green dot is not visible please refer to your admin.
The setup for Android and iOS is similar. Simply provide the extension number, password and domain received from your admin.
The following steps apply to the Impact Phone for Windows only. For Android and iOS nothing further is required.
2. Recommended Settings for Impact Phone for Windows
In order to avoid audio issues we recommend the following settings on your Impact Phone. In future versions of the Impact Phone these will be set by default in the settings.
2.1 Codecs Settings

Go to “…” > Preferences > Audio. Deactivate all codecs except PCMU, PCMA, G.722, GSM as shown below and move them to the top of the list.
2.2 STUN Server Settings
Impact Phone for Windows
Go to “…” > Preferences, click on the edit button of your account. Then set “Transport” to “UDP”, Enable ICE and add stun.l.google.com:19302 (not like in the pic: stun01.impactpbx.com) as STUN Server.
Don’t forget to click “Done” to save the settings.
Now you are all set up and ready to dial. Please keep in mind to use an international dialing format like 0044 XXXXXX if not advised otherwise.
3. Basic Settings
This section explains some of the Impact Phone's basic settings.
3.1 Audio Settings
Next to your name click on the three dots “…” and select “Preferences”.
Audio Settings
Here you can also configure the audio settings. In this example there is a USB Headset which is set up as playback and capture device. The ring tone on an incoming call is played by the computer speakers. Set it up to your requirements.
Use codecs PCMU and PCMA (G.711), G.722 and GSM and ensure they are enabled and at the top of the list (by grabbing and move them up) to avoid any codec-related audio issues.
4. In Call Features and Call Handling
This section provides information about the in call features available and how to handle multiple calls at the same time.
The above image is the window seen when in a call.
Add Call: You can add an additional call by providing the phone or extension number. This initiates a second call and puts the first call on hold.
Conference Call: Adds another call by providing phone or extension number and adds all calls into a conference.
Microphone button: Switches the microphone on and off.
Camera button: Switches video on and off.
Pause button: Puts an active call on hold.
Arrow button: Forwards an active call to another destination, e.g. a phone number or another extension (direct transfer).
Rec button: Records the active call or stops recording it.
Gear button: Gives access to the volume of the microphone and speaker as well as selection of the webcam.
Dialpad button: Shows or hides the dialpad.
How to check my voicemail
Dial your personal extension number to check your voicemail. For example, if your extension number is 1005 after you dial it you will be prompted to type in your voicemail pin followed by #. The voicemail pin is available from your administrator. From the menu you have the option to listen to messages, delete or store them and configure your voicemail.
Voicemails can also be attached to an email mailbox. This depends on the system configuration. Please ask your administrator.
How to handle multiple calls
If “Call Waiting” is enabled in the settings, you can handle several calls at the same time. If during a call a second call comes in, it will appear in the left pane under the currently active call and will also be signaled with a beep via audio.
By clicking on the three lines next to the call you can select what to do with the second call while still in the first call:
Accept Audio Call: Accepts the second call and puts the first call on hold. The first caller/callee will hear music while on hold.
Accept Video Call: This is the same as accepting an audio call, but the call gets answered using video (this only works if the caller also sends a video signal).
End Call: When you end a current call with a call waiting the forwarding rules on presence sets status to “Busy”. This is configured for your extension in the PBX. Default is to send the caller to Voicemail.
How to do an attended transfer
In an attended transfer, the first call is put on hold while you are speaking to a colleague when there’s a call for him/her. After speaking to your colleague, you put the call through to him/her.
When in the call click “Add Call” and dial your colleague's number/extension. The first call is put on hold while you speak with the colleague. When ready, end the call with colleague and resume the first call. Then click the Arrow button and forward the call directly to your colleague.
Additional features will be added in time which we will inform you about by updating this document. If you have any questions please feel free to contact us.
