To use VoIP extensions, you need to register the extensions on your IP phones or soft phones.

Yeastar provides Linkus mobile client. Linkus helps you set up your phone efficiently and links you and your colleagues and customers anywhere anytime.

We have tested a number of IP phones and soft phones with Yeastar S-Series VoIP PBX. Below is an example of registering an extension on Yealink phones.
