Product Features

4-Port 4G LTE Connectivity

The Yeastar TG400L provides four mobile channels, allowing businesses to connect multiple SIM cards and mobile lines to their VoIP telephone infrastructure. This makes it suitable for organizations that need additional mobile calling capacity or multiple cellular routes.

Mobile-to-VoIP and VoIP-to-Mobile Calls

The TG400L provides two-way communication between GSM/3G/4G networks and VoIP networks. This allows incoming mobile calls to be routed to IP phones or a PBX and outgoing VoIP calls to be routed through selected mobile channels.

4G LTE Support

The gateway connects compatible mobile networks to IP telephone systems using 4G LTE technology. Yeastar’s documentation also provides configuration options for selecting the network type and band manually when automatic network selection is not suitable.

VoLTE for HD Voice

The TG400L supports VoLTE when the installed LTE module, SIM card, mobile network and regional configuration support the feature. VoLTE enables voice calls to be carried over a 4G LTE network.

SIP and IAX2 Support

The TG400L supports SIP and IAX2 protocols, allowing it to integrate with compatible IP PBXs, SIP platforms and softswitches.

Least Cost Routing

Least Cost Routing can help businesses select preferred routes for outgoing calls based on configured routing rules, potentially helping to reduce telephone expenses.

Call Back Function

The Call Back feature provides an additional method of managing outbound mobile communications and can be useful in deployments where businesses need greater control over calling costs.

Advanced Call Routing

Administrators can configure incoming and outgoing routing rules to determine how calls are handled between mobile channels, VoIP trunks, IP PBXs and other destinations.

Mobile Port Groups

The TG400L supports mobile port grouping, allowing administrators to organize the four mobile channels and apply routing policies according to the organization’s requirements.

SIP Trunk Integration

The gateway can be integrated with IP PBX systems as a mobile trunk, allowing businesses to extend cellular connectivity into their existing VoIP telephone infrastructure. Yeastar provides integration guidance for connecting TG gateways with its P-Series IP PBXs.

IP PBX and 3CX Integration

The TG400L can be integrated with compatible third-party IP PBX platforms. Yeastar provides configuration documentation showing how TG400 can be connected to 3CX for making and receiving calls through its GSM trunks.

SMS Support

The TG Series supports mobile communication features including SMS, making the gateway useful for organizations that need to integrate mobile messaging with business communication workflows.

Backup Communication Solution

The TG400L can provide a cellular fallback route when landlines or primary SIP connections become unavailable. It can also be used to increase call traffic capacity by providing additional mobile dial tones.

Echo Cancellation

The TG400L uses ITU-T G.168 Line Echo Cancellation to help reduce echo and improve voice quality during calls.

Network Security

The gateway provides networking and security features including firewall, OpenVPN, VLAN, QoS, static routes, DDNS and network attack alerts, helping administrators secure and manage the device within a business network.

Web-Based Management

The TG400L can be configured and managed through a web-based interface, allowing administrators to manage mobile channels, VoIP settings, routes and network configuration from a central interface.
