Increase your PBX’s analog capacity without replacing the main unit. Install FXS modules for analog phone extensions or FXO modules for PSTN trunks. Mix and match modules to match your exact requirements. Benefit from native PBX management for all channels. The EX08 delivers cost-effective expansion with full feature access, making it ideal for businesses that need to grow their analog connectivity while leveraging modern VoIP capabilities.

Detailed Use Cases and Compatibility

Analog Extension Expansion

Businesses with existing analog phones add FXS modules to the EX08 for direct PBX integration. Each FXS port supports one analog extension with full PBX features like voicemail, call forwarding and ring groups. Perfect for departments still using legacy handsets or fax machines.

PSTN Trunk Addition

Organizations connect traditional landlines via FXO modules. The EX08 registers each FXO port as a SIP trunk inside the S-Series PBX. Inbound PSTN calls route to IP extensions, IVR or queues. Outbound calls use analog lines for local dialing or failover.

Hybrid Analog-VoIP Environments

Companies transitioning to VoIP keep critical analog lines while expanding IP capacity. Mix FXS and FXO modules on one EX08 card. The PBX handles unified routing, recording and reporting across analog and IP channels.

Hotel and Hospitality Deployments

Hotels use FXS modules for room extensions and FXO for external lines. The EX08 integrates with PMS systems through the PBX. Wake-up calls, do-not-disturb and check-in/out synchronization work seamlessly across analog room phones.

Compatibility and Integration

The Yeastar EX08 is compatible with Yeastar S-Series VoIP PBX models including S50, S100 and S300 (check specific model slot availability). It supports up to two EX08 cards per PBX depending on model. The card uses RJ11 ports for FXS/FXO modules (modules sold separately). Full management occurs within the S-Series web GUI, including channel status, trunk configuration, call routing and signal monitoring. Compatible with standard analog phones, fax machines and PSTN lines.
