The phone number keeps its old SIP destination even after you edit it. ## **Why this happens** There are 2 common reasons. **Reason 1** **The SIP destination isn't in the exact format ServiceTitan expects.** The forwarding number field only accepts the SIP destination in one specific format. If the format is off, the change won't stick. **Reason 2** **You don't have the permission that allows editing the field.** Editing the forwarding number requires a specific permission. If that permission is missing, the change won't save. ## **How to fix it** **Before you start** You need the **Forwarding number settings** permission to make this change. This permission is not always enabled by default, even for administrators, so if you cannot edit the field, ask your admin to turn it on for you and anyone else who needs access. ### **1****Re-enter the SIP number in the correct format** 1. Go to **Settings > Phones > Phone Numbers**. 2. Find the phone number associated with the marketing campaign, and in its **Forwarding number settings** field, enter the new SIP number. Use this format: `sip:+1XXXXXXXXXX@IP ADDRESS:5060` 3. Click **Save**, then refresh the page to confirm the new SIP number stuck. > [!NOTE] > **Note:** If you are on Phones Pro or Contact Center Pro, this field may be labeled **Set Call Continuity Number** rather than **Forwarding number settings**. It is the same forwarding field. > [!NOTE] > **✓ Done ·** The phone number shows the new SIP destination after you refresh. ## **Still not working?** Contact ServiceTitan Technical Support at [**go.servicetitan.com/ask**](https://go.servicetitan.com/ask) with: - Your tenant name and the phone number / campaign affected - The SIP number you're trying to set (including the format you used) - Whether you hit a permission error or the change simply didn't save - A screenshot of the **Forwarding number settings** field ## **Want to learn more?** [**Change your Set Forwarding Number in ServiceTitan ›**](https://help.servicetitan.com/construction/docs/change-your-set-forwarding-number-in-servicetitan) Step-by-step guide to setting and updating the forwarding (SIP) number on a phone number.
