Getting Started with IP Phones

Telzio enables you to use numerous different types of office phones with your service, including desk, wireless, and conference phones. Telzio provides an internet-based phone service, which means that office phones are powered by your existing internet connection, and using IP phones is recommended.

IP phones function similar to traditional office phones, except IP phones connect to a router or adaptor to run through your internet service, as opposed to traditional phones that connect to a landline telephone jack. Any SIP compatible IP phone will work with Telzio, such as phones from Yealink, Grandstream, Cisco, and Polycom. IP phones come in a wide range of price points and functionality, and we’re happy to provide recommendations on the best phones for your business.

You can purchase preconfigured IP phones from our shop that arrive ready for calling, and use existing IP phones and configure them by following our step-by-step support guides. It’s important to note that we can only provide limited support on phones that are not purchased directly from our shop.
