The Voip Office mobile app for iPhone offers users the ability to make VoIP calls over Wi-Fi or 3G/4G networks without using carrier minutes. With this app, you can manage all of your business calls, voicemails, and SMS messages from your mobile device, even when you're away from the office.

One of the key features of Voip Office is the ability to show your business number as your caller ID when making outbound calls from your cell phone. This helps maintain a professional image and ensures that clients and customers recognize your business number. Additionally, the app tracks call history, making it easy to return calls directly from the mobile app.

The app also offers convenient features such as Quick Dial, which allows you to store favorites for quick access to place a call or send an SMS message. Contact Integration is another useful feature that enables you to integrate all your contacts into the app for easy access.

For those who frequently travel internationally, Voip Office allows for unlimited calling to the US and Canada. This is a great feature for business professionals who need to stay connected while on the go.

Please note that Voip Office for iPhone requires an existing Voip Office account.
