OpenVox iAG840 4-Port FXS Analog VoIP Gateway
The OpenVox iAG840 connects analog telephone equipment to SIP-based voice networks through four FXS ports. Designed for small businesses and small offices, it helps retain existing analog phones while moving voice services to an IP-based system.
This Asterisk-based gateway combines SIP connectivity, fax support and browser-based configuration in a compact enclosure. It is suited to deployments that need analog extensions connected to a compatible IP PBX or SIP server.
Key Features
- Four FXS ports for analog telephone equipment.
- Standard SIP connectivity for integration with compatible voice platforms.
- T.38 fax relay and T.30 transparent fax support.
- Web GUI for configuration and status monitoring.
- Echo cancellation, static jitter buffer and DTMF relay.
- Configurable ring cadence, volume and country-specific tones.
Voice and Fax Technology
Supported codecs include G.711A, G.711U, G.729, G.722, G.723, G.726 and iLBC. Fax functionality supports integration of suitable analog fax equipment into a compatible VoIP environment.
Connectivity
The gateway provides four FXS interfaces and one Ethernet LAN port. Network configuration supports static IP addressing, DHCP, DNS/DDNS and NAT networking.
Management and Integration
Administrators can use configuration backup and upload, firmware update functions, logs and NTP time synchronization. Asterisk Management Interface access and editable dial plans support customized integrations.
Power
The iAG840 uses an external 12V DC power supply. Confirm the correct adapter for the supplied hardware before installation or replacement.
Ideal Applications
- Connecting existing analog telephones to a SIP-based phone system.
- Small business and home office VoIP migration.
- Integrating analog fax equipment into a supported IP telephony deployment.
Compatible Products
The iAG840 provides FXS interfaces for analog telephone equipment. Its IP connection requires a compatible SIP platform, matching codecs and correctly configured registration and call routing.
OpenVox identifies the following software platforms in its original compatibility documentation:
- Asterisk – documented SIP platform integration.
- FreeSWITCH – documented SIP platform integration.
- 3CX – named in the original manufacturer documentation; confirm support for the intended version before deployment.
- Elastix – named in the original manufacturer documentation.
Important: These references do not establish compatibility with every current software release or hosted service. Confirm version-specific SIP, authentication, codec and fax requirements.
Important: The four analog ports are FXS ports for telephone-side equipment. They are not FXO inputs for connecting telephone-company analog lines. Do not connect an active PSTN line or another FXS output to these ports.
