Product information

Description

Yeastar S20 is a compact, entry-level VoIP gateway and PBX controller designed for small businesses with up to 20 users. It supports 10/100 Mbit/s Ethernet, multiple voice codecs (G.711, G.722, G.726, G.729A) and common VoIP protocols (SIP, IAX2) with transport options including UDP, TCP, TLS and SRTP. The device combines a modular telephony interface design with a small desktop or wall-mount form factor and low power consumption, providing a reliable on-premises phone system that integrates with Linkus UC softphone and Linkus Cloud Service.

Advantages

The Yeastar S20 provides a rich set of built-in PBX features—call routing, IVR, conferencing and call recording—without extra licensing fees, plus CRM integrations (Salesforce, Microsoft Dynamics 365, Outlook and Google Contacts). Its modular design supports two onboard module slots for FXS, FXO, ISDN BRI or GSM/3G/4G interfaces, enabling flexible telephony combinations. Remote Management tools allow secure centralized monitoring and maintenance, while the App Center adds optional functionality such as hotel management, billing or call center integration.

Suitable for

Small offices and businesses with up to 20 users
Environments needing a compact desktop or wall-mounted PBX/gateway
Sites requiring SIP/IAX2 VoIP connectivity with secure transport (TLS/SRTP)
Installations that benefit from modular telephony interfaces (FXS/FXO/BRI/GSM)

Key specifications

Supported codecs: G.711, G.722, G.726, G.729A

MPN / EAN: 10000165 / 6926150036918

How to use

Install the Yeastar S20 on a desk or mount it on a wall, then connect it to your local Ethernet network (10/100 Mbit/s). Insert the required telephony modules into the two onboard slots to provide FXS/FXO/BRI or GSM connectivity as needed. Configure SIP or IAX2 accounts via the web management interface, set up dial plans, IVR and extensions, and integrate Linkus UC softphone or Linkus Cloud Service for remote and mobile users. Use the Remote Management tool to monitor and maintain the PBX centrally.

Usage recommendations

For reliable voice quality, use supported codecs (G.711 or G.722 where bandwidth allows) and enable TLS/SRTP for secure signaling and media. Keep the firmware up to date, back up configuration regularly, and select telephony modules based on required PSTN or mobile connectivity to match your deployment needs.
