1300035 Yealink Yealink T4 Series Phone Accessory

The Yealink 1300035 is the Expansion Module 38 (EXP38), a sidecar accessory designed to extend the functionality of compatible Yealink SIP desk phones. This module provides 38 additional programmable keys with dual-colour LED indicators, allowing users to configure speed dials, BLF (Busy Lamp Field) monitoring, and other telephony functions directly from the attached unit.

The EXP38 is intended for use in busy reception areas, contact centres, and executive environments where users need quick access to a large number of extensions or call handling features. Multiple expansion modules can typically be daisy-chained to a single supported handset, significantly increasing the available programmable keys.

This expansion module is designed for use with Yealink’s mid-range and high-end SIP phone series, providing a cost-effective way to enhance call handling efficiency without replacing existing handsets.
