This process involves generating unique SIP credentials in the Webex Control Hub and then manually entering them into the Fanvil web interface.  Step 1: Generate SIP Credentials in Webex Control Hub  Log in to the Cisco Webex Control Hub with administrator credentials. Navigate to Management \> Devices and click Add Device. Choose Existing User or Workspace depending on where you want the device assigned. Select Cisco Phone, ATA, or 3rd Party Device. From the drop-down menu, choose Customer Managed Device. Select Generic IP Phone (or similar) as the device model. Enter the device's MAC address and click Save. Webex will generate a SIP Username, SIP Password, and Outbound Proxy (e.g., lbgw.cisco.com). Copy these details immediately or download the provided .csv file.  Step 2: Configure the Fanvil A233 Web Interface  Access the Fanvil web UI by entering the device's IP address into a browser (default credentials are often admin/admin). Go to Line \> SIP settings. Fill in the following fields using the credentials from Step 1: Display Name: Your preferred name. User Name: The SIP Username from Webex. Authentication Name: The same SIP Username. Password: The SIP Password generated by Webex. SIP Server 1 (Address): Set this to the Webex domain (e.g., cisco.sipflash.com or as specified in your Control Hub). Server Port: Usually 5061 (for TLS) or 5060. Transport: Select TLS (Webex generally requires encrypted signaling). Under Proxy Settings: Enable Proxy: Yes. Proxy Address: Enter the Outbound Proxy provided by Webex. Click Apply/Save.  Step 3: Verification On the Phone: Check the registration status on the Fanvil dashboard; it should show "Registered." In Webex: The device status in Control Hub should change from "Offline" to Online within a few minutes - [Cloud Management Platforms](https://help.voipsupply.com/migration/en/knowledge/cloud-management-platforms?hsLang=en#main-content) - [Fanvil](https://help.voipsupply.com/migration/en/knowledge/cloud-management-platforms?hsLang=en#fanvil) - [SIP Paging Gateway](https://help.voipsupply.com/migration/en/knowledge/sip-paging-gateway?hsLang=en#main-content) - [Fanvil](https://help.voipsupply.com/migration/en/knowledge/sip-paging-gateway?hsLang=en#fanvil) - [Device Factory Resets](https://help.voipsupply.com/migration/en/knowledge/device-factory-resets?hsLang=en#main-content) - [Fanvil](https://help.voipsupply.com/migration/en/knowledge/device-factory-resets?hsLang=en#fanvil) - [SIP Register Configuration](https://help.voipsupply.com/migration/en/knowledge/sip-register-configuration?hsLang=en#main-content) - [Fanvil](https://help.voipsupply.com/migration/en/knowledge/sip-register-configuration?hsLang=en#fanvil) - [Provisioning Devices](https://help.voipsupply.com/migration/en/knowledge/provisioning-devices?hsLang=en#main-content) - [Grandstream GXW42XX / VoIP Gateway](https://help.voipsupply.com/migration/en/knowledge/provisioning-devices?hsLang=en#grandstream-gxw42xx-voip-gateway) - [Broadcast / Multicast](https://help.voipsupply.com/migration/en/knowledge/broadcast-multicast?hsLang=en#main-content) - [Fanvil](https://help.voipsupply.com/migration/en/knowledge/broadcast-multicast?hsLang=en#fanvil) - [Device / Network Configuration](https://help.voipsupply.com/migration/en/knowledge/device-network-configuration?hsLang=en#main-content) - [Fanvil](https://help.voipsupply.com/migration/en/knowledge/device-network-configuration?hsLang=en#fanvil) - [Grandstream](https://help.voipsupply.com/migration/en/knowledge/device-network-configuration?hsLang=en#grandstream) - [Yeastar PBX](https://help.voipsupply.com/migration/en/knowledge/device-network-configuration?hsLang=en#yeastar-pbx) - [Poly / HP](https://help.voipsupply.com/migration/en/knowledge/device-network-configuration?hsLang=en#poly-hp) - [Network Troubleshooting](https://help.voipsupply.com/migration/en/knowledge/network-troubleshooting?hsLang=en#main-content) - [Yeastar PBX](https://help.voipsupply.com/migration/en/knowledge/network-troubleshooting?hsLang=en#yeastar-pbx) - [Backup & Restore](https://help.voipsupply.com/migration/en/knowledge/backup-restore?hsLang=en#main-content) - [Yeastar Backup & Restore](https://help.voipsupply.com/migration/en/knowledge/backup-restore?hsLang=en#yeastar-backup-restore) - [PBX Licensing](https://help.voipsupply.com/migration/en/knowledge/pbx-licensing?hsLang=en#main-content) - [Switchvox PBX](https://help.voipsupply.com/migration/en/knowledge/pbx-licensing?hsLang=en#switchvox-pbx) - [Provisioning Services](https://help.voipsupply.com/migration/en/knowledge/provisioning-services?hsLang=en) VoIP Supply Help Center Copyright © 2026, VoIP Supply
