How do I enable mobile VoIP calling?

One of the features of the Office@Hand mobile app is VoIP Calling which enables you to make phone calls over the Internet, without consuming your airtime minutes. There is no additional charge for this feature and is available for both iOS and Android-powered devices.

Mobile VoIP calls can be placed using WiFi or mobile data connection, and can also be received directly on the mobile app.

VoIP Calling Over 3G / 4G Data Connection

 

Things to know about VoIP Calling through 3G / 4G Data Connection

 

  • When a VoIP call is placed or received through a WiFi connection and the WiFi fails, the VoIP call will not be disconnected and will continue through the phone’s data connection, if the mobile app is set to Always Use VoIP.
  • When a VoIP call is placed or received through a WiFi connection and the WiFi fails, the VoIP call will be disconnected, if the mobile app is set to Use VoIP only on Wi-Fi.
  • Voice quality on 3G/4G LTE depends on network data quality E.g., if a user moves away from good data coverage area to a bad data coverage area (e.g. driving in a car), VoIP calls through 3G/4G may have voice quality issues.
  • VoIP Calling through 3G/4G LTE will be charged against your phone’s data allocation.

Incoming VoIP Calling

 

Things to know about Inbound VoIP Calling

 

  • Inbound VoIP calling is turned ON by default on Wi-Fi connections.
  • On iOS (version 8.0 and up), incoming VoIP calls to the Office@Hand mobile app will come in regardless of the app running or not. This is the case even if the mobile app is manually killed via Task Manager, or automatically put to sleep by the OS.
  • On iOS, even when the Office@Hand mobile app is displayed in the Task Manager this does not necessarily mean that the app is running. The OS controls if and when the apps run and may put the app to sleep at any time. Your Office@Hand mobile app will wake up so that you can receive the incoming VoIP call even if your app is not running. If you want to block incoming VoIP Calls temporarily, please turn off the VoIP Calling setting in the mobile app.
  • Incoming Call Notifications to the Office@Hand desktop app and smartphones should be enabled for the inbound VoIP calling to work. This is set inside the device’s settings. For more information, go to Customizing a User’s Call Handling and Forwarding Rules through the Office@Hand Mobile App.
  • The Office@Hand desktop app and mobile app gets the incoming call notification simultaneously.
  • Voice quality on 3G/4G LTE depends on network data quality E.g., if a user moves away from good data coverage area to a bad data coverage area (e.g. driving in a car), VoIP calls through 3G/4G may have voice quality issues.
  • The Office@Hand mobile app uses your phone’s native ringtone and has support for vibrate mode.
  • Depending on the device model, users may need to unlock the phone’s screen before answering the call.

    Note: Battery may drain quicker on some Android models with inbound VoIP enabled.

How to Enable / Disable Inbound VoIP Calling

Using the RingOut feature

When there is no connection available (Wi-Fi/3G/4G), the RingOut feature on the Office@Hand mobile app will allow you to use a non-Office@Hand device for placing a call, and then send your Office@Hand phone number as your Caller ID to the party you are calling.

How does it work?

RingOut calls you on your RingOut Number first, and then connects you to the desired number. The RingOut Number is the phone number assigned to the device where you want to pick up the RingOut call, to connect to the other party. When the call is connected to the dialed number, Office@Hand shows your Office@Hand business number as your Caller ID. Office@Hand hides your personal phone numbers when using your home or cell phone.

Enabling RingOut on your Office@Hand Mobile App

To start placing phone calls via RingOut, you need to enable it on your Office@Hand mobile app. Follow the steps below:

  1. Log in to your Office@Hand Mobile App.

  2. Tap on your Profile Picture.

Android Devices

When a regular call comes in while on a VoIP call, the behavior will depend on the model and OS version of your Android phone. You will be notified that there is a regular incoming call, and will get the chance to decline or answer.

  • During the notification, the person on the other end of the VoIP call will not be placed on hold.
  • When you choose to answer the regular incoming call that is the only time that the VoIP call will be placed on hold.
  • When you decline the regular incoming call, you can automatically continue with the VoIP call.
  • When you answered the regular incoming call and finished with it, you will need to tap Hold to go back to the line and continue with the VoIP call.

    Android device screen.

iOS Devices

When making or receiving a VoIP call on your iOS device through the Office@Hand mobile app for the first time, you will encounter the following message:

IMPORTANT: Due to iOS system design, incoming iPhone calls will interrupt VoIP calls. Reject the iPhone call to continue your VoIP call, or answer it to place the VoIP call on hold.

If a regular call comes in while on a VoIP call, you can take the iPhone call, reply with a message, be reminded of the call at a later time or reject the call.

Note: When you get a regular call on your iPhone, the party on the other end of the VoIP call will be placed on hold automatically and will not hear anything. If you accept the regular call, the person on the other end of the VoIP call will be put on hold and will hear your hold music. After you hang up from the regular call or if you reject the incoming regular call, the VoIP call will be retrieved automatically so you can proceed with the VoIP call.

Reconnecting Message on VoIP Calls

When a VoIP call is disconnected, the call will be automatically reconnected. Users will hear a reconnecting sound, indicating the call is being re-established. You will see a “Reconnecting…” notification in the mobile app’s active call screen.

Slow Internet: Option to Switch to RingOut

The Office@Hand mobile app displays smart recommendations when it detects that the network quality may affect the VoIP call quality. Users will get a pop-up that will provide the option top Switch to RingOut, or Continue with VoIP.
