# How do I set up Phonesuite CTI with Outlook integration?
With PhoneSuite **hardware VoIP phones** & softphones can be connected. Likewise, the PhoneSuite Client can act as a **Softphone** interface. Outlook integration is also possible in order to **synchronize** the Outlook contacts with PhoneSuite, but also to make calls directly from Outlook.
{% hint style="warning" %}
**Attention:** Zoiper is supported by PhoneSuite, but only the 32-bit version of Zoiper 3 Premium/Business (BIZ). For this article, the PhoneSuite SIP SoftPhone was used. During installation, the Outlook plug-in was also installed, or all three options were activated.
{% endhint %}
{% stepper %}
{% step %}
**Configure softphone**
After installation on **Phone configuration** click and in the tab **TAPI device** the button **Select TAPI device** press. Now choose the option **SIP SoftPhone** and click on **Device configuration** . Of course, several other options are also possible, such as connecting with Zoiper, Snom, Yealink, FRITZ!Box, etc. However, we will limit ourselves here to the SIP SoftPhone.
Now the SIP configuration appears. Please edit it. The entries should look as follows
**SIP service provider**
Name: sipgate
IP address: sipgate.de
Use STUN server: disabled
Pickup: \*9 (+ phone number active)
DTMF: RFC2833
**SIP registration data**
User ID: the SIP ID of your phone
Authentication name: the SIP ID of your phone
Password: the SIP password of your phone
Display name: empty
Extension number: internal extension
{% hint style="info" %}
You can find your SIP registration data in the account management via the tile **User.** Click in the desired user on the VoIP phone you want to configure. An info box will open there with all the data you need for the configuration. From this you can obtain the SIP ID and the SIP password.
{% endhint %}
Complete the setup by pressing **OK** and select the SIP SoftPhone, i.e. mark it and then click below on **OK (Select TAPI device)** . This sets up PhoneSuite as a VOIP softphone. Please make sure that under the option **Audio** you have configured the correct input and output audio devices and have enabled access to the microphone in the Windows privacy settings.
Currently, the caller's name is only displayed for internal contacts, i.e. users in the account. For more convenience, we will now first set up the BLF function and then the Outlook integration.
{% endstep %}
{% step %}
**Set up BLF function**
If you move your mouse all the way to the top, a speed-dial field appears. You also have a speed-dial field on the main window. Click on one of the empty fields and press **Edit**. Now enter the following information and save the entry:
Action type: dial number
Button name: employee name
Phone number: the employee's internal extension
SIP user ID: see phone number
Dial via this TAPI device: SIP SoftPhone
Monitor LED: click on "..." and select the configured softphone
{% hint style="info" %}
Important: The BLF function is only available from the sipgate business L plan onward.
{% endhint %}
{% endstep %}
{% step %}
**Activate Outlook integration**
Proceed as follows:
**Options ➔ Outlook ➔ Activate Outlook Add-In ➔ Enable automatic synchronization of Outlook contacts**
{% endstep %}
{% endstepper %}
