WHY CHOOSE THIS PRODUCT?

• Organizations using compatible Yealink phones can add PSTN capability without replacing the existing endpoint, making the CPN10 practical for phased telephony modernization and environments where analog lines remain operational. Its dedicated RJ11 interface, USB 2.0 recording support and two-unit cascading capability provide more deployment flexibility than a basic cable adapter, while plug-and-play operation and no additional power requirement keep installation simple. For procurement teams, it is particularly relevant when extending the lifecycle of compatible Yealink conference or desk phones, retaining existing PSTN infrastructure, or creating hybrid SIP and PSTN conference environments.
