Yeastar EX30 Module

The Yeastar EX30 is an add-on card for Yeastar S100 and S300 VoIP phone systems letting you connect your existing phone system, which might use traditional phone lines, to your newer VoIP system. Think of it like a translator that allows both systems to talk to each other. If you're looking to upgrade your business phone system to a more modern VoIP solution, but still have some traditional phone lines you need to use, the Yeastar EX30 can help make that switch smoother.
