innovaphone IP29-20 FXS Package — 2× IP29-20 units with 19" rack and FXS license (MPN 88-00010-123)

The innovaphone IP29-20 FXS Package contains two IP29-20 VoIP gateway units together with a 19" rack mounting kit and an FXS license. Each IP29-20 provides FXS ports to connect analogue telephones or devices to a SIP-based VoIP infrastructure, enabling integration of legacy equipment with modern IP PBX systems. The package is designed for small office environments where analogue extension support, migration to SIP, or hybrid setups are required.

Advantages

The package combines two compact IP29-20 gateways that offer FXS connectivity for analogue handsets and fax machines while maintaining SIP compatibility for integration with existing VoIP platforms. Including a 19" rack kit simplifies installation in standard rack enclosures and the bundled FXS license ensures the required functionality is available out of the box. The solution is space-efficient and intended to reduce complexity when integrating analogue endpoints into SIP-based communications.

Suitable for

• Small office PBX integration where a few analogue extensions are needed
• Migrations from analogue or hybrid systems to SIP infrastructure
• Connecting analogue telephones, fax machines or POS terminals to a VoIP network
• Installations requiring rack mounting of compact gateway units

When it may not be suitable

This package is focused on providing FXS interfaces for analogue devices and is not intended as a full-featured large-scale media gateway for many simultaneous channels. Environments that require high-density FXO/FXS port counts, carrier-grade trunking, or advanced transcoding at large scale may need a different class of gateway. It also does not replace an IP PBX; it is designed to complement SIP-based telephony systems by adding analogue endpoints.

Key specifications

• Number of gateway units: 2 compact IP29-20 devices
• Interface type: FXS ports for analogue extensions
• Compatibility: SIP-based VoIP platforms and IP PBX systems
• Mounting: 19" rack mounting kit included for both units
• Licensing: FXS license included to enable analogue port functionality
• Use case: Designed for small office and branch deployments

How to use

Install the two IP29-20 units in a standard 19" rack using the supplied mounting kit, connect each device to the local network via Ethernet, and power them according to the manufacturer instructions. Configure SIP account settings on each gateway to register with your IP PBX or SIP provider, then connect analogue telephones or fax machines to the FXS ports. Apply the provided FXS license through the device management interface to enable the analogue port functionality. Verify call routing, DTMF handling and fax pass-through where applicable, and adjust QoS settings on the network to prioritise voice traffic.

What to consider before purchase

• Confirm the number and type of analogue devices to be connected and whether two IP29-20 units provide sufficient FXS ports
• Ensure compatibility with your IP PBX or SIP provider and check required SIP credentials
• Assess rack space availability for a 19" installation and any additional power or network requirements
• Plan for network QoS and security settings to support voice traffic reliably

Usage recommendations

Use the innovaphone IP29-20 FXS Package to add a limited number of analogue endpoints into a SIP environment, place the gateways in a controlled rack location with stable power and network connectivity, and perform initial testing of analogue device behaviour (handset audio, fax tone detection and DTMF) before full deployment.
