The W52P is Yealink's IP-DECT Cordless Phone, designed for SME's looking for a scalable and flexible SIP-based mobile communications system. The W52P is a complete system that can be expanded with a further five W52H Handsets.

The W52P is a complete business-grade SIP Cordless Phone. This state of the art IP-DECT solution supports up to 5x W52H cordless IP-DECT Handsets per Base Station, and is designed for enterprises who are looking for a scalable SIP-based mobile communications system that provides immediate cost savings.

The W52P supports the G.722 high definition voice codec and the CAT-IQ2.0 standard (fully backwards compatible to the DECT GAP standard), ensuring crystal clear calls and a low data bit-rate.

Combining the benefits of DECT wireless communication with the rich business features of Voice over IP telephony, users can benefit from freedom of movement, lifelike HD audio voice communications, multi-tasking convenience and professional features like intercom, transfer, call forward, 3-way conferencing and PoE support.

A W52P System can register handsets as extensions of the company IP-PBX. The system is fully compatible with widely-known IP-PBX systems including Broadsoft, Asterisk, 3CX, Epygi Quadro and Zultys.
