Features and Functionality

OnSIP comes with a multitude of beneficial features including (but not limited to):

Personal attendant

The OnSIP personal attendant can answer phone calls for you and provide the caller with different options. For example, if you are unable to answer an important call for some reason, you can configure your attendant to play this message for you: “sorry for not being able to receive your call. Press 1 to record a voicemail, 2 to try my cell phone, and 3 to contact our support team.”

Advanced voicemail features

OnSIP makes voicemail faster, more efficient and more accessible. You can get your voicemail sent directly to your email. From there, you can listen to the .wav file attachment, call the OnSIP voicemail system with your extension and pin, or listen to your voicemail using the OnSIP application.

Intuitive auto-attendant

With OnSIP, setting up an auto-attendant is very straightforward. You can maximize its true potential by playing a pre-recorded message to all your callers prompting them to select different numbers to get connected to particular people or departments.


With OnSIP, you can divide and conquer. If your business is divided into different teams, you can use groups to manage a sea of callers efficiently. For example, you can set up a ring strategy for your sales team so that your leads are always easily identified from other callers.

Admin API

An exciting feature offered by OnSIP is its admin API. It allows you to automate and/or integrate your OnSIP account’s integration. From creating a user to assigning a voicemail box, you can perform all the features of the administrative portal (and then some) using the admin API.

Desktop Apps

OnSIP also offers free-to-download desktop applications. You can download said applications for Windows, Mac, and Linux platforms.

Ease of Use

Since OnSIP is cloud-based, you can set it up in a breeze. There is no need to install any hardware as long as you already have an internet connection, and you can start making calls right after registering. The interfaces for both the web-based and desktop applications are user-friendly and don’t pose a user learning curve. However, to even the most inexperienced users, the design can appear a bit dated. Overall, OnSIP scores fairly high on the usability charts, especially when compared to its counterparts.
