Multiple Ways to Connect to pbxHQ
Many of our customers ask, “Do I need new phones to use your PBX?” In short, the answer is no. If you own a smartphone like most, you can download an app and connect instantly.
To get the most out of your PBX experience, you will want to connect a SIP client. This includes physical VoIP phones and software phones, referred to as softphones. Of course, you can also forward calls to ordinary devices like landlines and mobile phones.
