Fax conversations appear alongside all your other channels in the Inbox, so everything stays in one place. Fax requires a dedicated fax number. A regular VoIP phone number cannot send or receive faxes. You will need to purchase a separate fax number from Settings before using this feature. ### **Buy a Fax Number** Before you can send or receive faxes, you need to purchase a dedicated fax number. 1. Go to **Settings** from the left sidebar. 2. Under **Account Settings**, click **Fax**. 3. Click the **Buy Numbers** tab. 4. Browse available fax numbers and select one that fits your needs. 5. Complete the purchase. The number will appear under the **Manage** tab once active. Once your fax number is active, you will see it listed with its alias, number of conversations, and default assignee. ### **Manage Your Fax Numbers** You can view and configure your fax numbers from **Settings → Fax → Manage**. Each fax number card shows: * **Number** — The fax number assigned to your account. * **Status** — Whether the number is Active. * **Alias** — A friendly name you can set to identify the number. * **Conversations** — Total fax conversations tied to this number. * **Default Assignees** — The team member automatically assigned to incoming faxes on this number. Click the three-dot menu (⋯) on any number card to edit its settings or release the number. ### **Send a Fax** Faxes are sent as PDF documents from the Inbox. #### **Start a New Fax Conversation** 1. Go to **Inbox** from the left sidebar. 2. Click **+ New Conversation**. 3. In the modal, click the **Fax** tab. 4. In the **From** field, select your fax number from the dropdown. 5. In the **To** field, enter the recipient's fax number (include country code, e.g., +1). 6. Under **What would you like to add?**, leave it set to **Reply** or select the appropriate option. 7. Under **PDF Document**, click the upload area and select a PDF file (max 50MB). 8. Click **Send Fax**. #### **Reply with a Fax in an Existing Conversation** If you are already inside a fax conversation in the Inbox: 1. Click the upload area at the bottom of the conversation that says **Click to upload a PDF (max 50MB)**. 2. Select the PDF you want to send. 3. Click **Send Fax**. ### **Receive a Fax** Incoming faxes are automatically routed to your Inbox as conversations tagged with **Fax**. Each fax message shows: * The number of pages in the document. * A download icon to save the PDF locally. * The timestamp of when it was received. You can assign the conversation to a team member, add notes, create tickets, or manage it like any other inbox conversation. ### **Troubleshooting** **Fax shows as "Failed"** This usually means the recipient's fax line was unavailable or rejected the transmission. Verify the destination number is a working fax line, not a regular phone number, and try again. **Fax shows as "Queued"** Your fax has been submitted and is waiting to be transmitted. This is normal during high-volume periods. It will send automatically once processed. No action is needed. **I can't select a fax number in the "From" field** You do not have an active fax number yet. Go to **Settings → Fax → Buy Numbers** and purchase one before sending. **My uploaded PDF was rejected** Make sure the file is a valid PDF and does not exceed 50MB. Files in other formats (Word, images, etc.) are not accepted. Convert the file to PDF before uploading. **I can't find incoming faxes in my Inbox** Use the filter icon in the Inbox search bar and filter by channel or tag. Incoming faxes are tagged as **Fax**. Also confirm the fax number has the correct default assignee set under **Settings → Fax → Manage**. ### **Frequently Asked Questions** **Can I use my existing phone number to send faxes?** No. Regular VoIP numbers in Z360 do not support fax transmission. You must purchase a dedicated fax number from **Settings → Fax → Buy Numbers**. **What file types can I send?** Only PDF files are supported. The maximum file size is 50MB per document. **Is there a limit on the number of pages I can fax?** There is no page limit enforced by Z360, but very large documents may take longer to transmit or may be limited by the recipient's fax hardware. **Can my AI agent send or receive faxes?** Not at this time. Fax conversations must be managed manually by a team member. **Can I have multiple fax numbers?** Yes. You can purchase additional fax numbers from **Settings → Fax → Buy Numbers** and manage them separately with different aliases and assignees. ### **Tips** * **Set an alias** for each fax number (e.g., "Main Office Fax") so your team can easily identify the right number when sending. * **Set a default assignee** on each fax number so incoming faxes are automatically routed to the right team member without manual reassignment. * **Check Attachments** in the right panel of a fax conversation to quickly access all PDFs exchanged in that thread.
