#### Common problems and notes

<details>

<summary><strong>Problem: Phone number is expanded with 20 and cannot be reached</strong></summary>

Cause: The linked phone number contains spaces in the “tel” link. According to RFC 3966, phone numbers in the link must not contain spaces.

{% hint style="info" %}
**Tip:** Hover over the phone number with your mouse. The link should look like this: ***tel:+49123456789*** (without spaces).
{% endhint %}

</details>

<details>

<summary><strong>Problem: Calling from Google Sheets is not possible</strong></summary>

Cause: Google interprets formulas such as =+49800... as arithmetic operations.

**Solution:** Save the phone number as =+498003301000 Double-click the cell with the phone number and then click the sipgate logo to start the call.

</details>

**Further notes**

The extension also works with connected CRM systems (e.g. HubSpot or Salesforce), provided that phone numbers there are linked in tel: format.\
Make sure that your browser allows pop-ups for sipgate so that the app can start the call.

If you have any questions or problems, please contact sipgate Support.
