Zycoo IPPBX is built on the Asterisk platform and supports the standard SIP protocol. It can connect to IMS SIP trunks from ITSPs (Internet Telephony Service Providers) as well as SIP endpoints.
This document provides instructions for sending and receiving faxes using the Virtual Fax application on the Zycoo IPPBX.
Log in to the IPPBX web interface using the admin account.
Navigate to Telephony → Extensions → IP Extensions
Click the Edit button for extension 809, then enable Web Login.
Log out from the admin user account
Log in again using extension 809 and its extension password
After logging in, click the Fax icon.
Configure the following parameters:
| Parameter | Description |
|---|---|
| Fax Number | The destination fax number of the recipient |
| File | Upload the document to be faxed (supported formats: PDF, TIF, TIFF) |
Important: After the file has been completely uploaded, click the Send button. Please ensure that your system can make outbound calls successfully before sending a fax.
After several minutes, you can check the Fax Log to verify the status of the sent fax.
Navigate to Telephony → Outbound Control → Trunks
Click the Edit button for the FXO-1 trunk
Configure the Fax Destination for the trunk
Result: When a fax is sent to the FXO-1 port, the system will automatically handle the fax reception.
For SIP or E1 trunks, you may need to configure DID routing to the fax destination:
Navigate to Telephony → Inbound Control → Direct Routing
Click the Add button to create a fax destination
Configure the DID to point to the fax destination
Result: You can now receive faxes from outside calls routed via DID.
If you have an IVR prompt configured, you can set a key press option to route calls to fax:
Navigate to Telephony → Inbound Control → IVR
Click the Edit button for the desired IVR
Configure a key press (e.g., press 1) to route to Fax
Navigate to Reports → Log → Fax Log
The Fax Log will show all received faxes and their status.
Navigate to Telephony → Extensions → IP Extensions
Click the Edit button for extension 809 and fill in the Email Address field.
Important: Before Fax to Email can function, you must first configure the Mail Server Settings under System → Email Services.
Once the mail server is properly configured, received faxes will be automatically sent to the configured email address.
