How often do you think about masking your personal phone number? The question may seem strange for the first sight, but imagine the situation when you ordered a taxi and after the order had done the driver started calling you. This is not what you expected from the taxi service, right? On the other hand, look at it from the driver’s point of view. It isn’t great if previous customers would call and distract the driver during the work or (even worse) during the vacation.
Firstly, to have a delicate distance between you and service workers is rather better than have no one. Secondly, it is important for both sides to have the fastest way to contact each other. The Voximplant cloud can easily meet these requirements via Phone number masking approach. This article will guide you through all necessary steps to implement this functionality for the simplified case of only one driver and a few customers. Note that this solution is scalable for any number of drivers and customers.
The latest version of our Web SDK is fully compatible with the new Safari 11 audio/video calls support. Please note that Safari imposes a number of restrictions for voice/video usage:
- Web page should load with HTTPS
- If voice or video call is initiated from iframe, this iframe and all iframes in-between should be loaded from the same domain as a website that loads them
- Video will not autoplay on iOS Safari browser without the explicit user command.
- Only H.264 video codec is supported, so set H264first flag to “true” while initializing the Web SDK.
User interface should be created in order for video to play during a call. It should be interactive element like an HTML “button” with “onclick” handler that calls “play” method on the “video” HTML element.
A brand-new messaging API was added across Web, Android and iOS SDK. Single Voximplant user id can be used to log in from multiple SDK instances, with API to send online and offline messages across one-on-one or multi-user conversations. Both our client and server-side are highly optimized for minimal resource usage and push notifications support.
- One Voximplant user id can be used to login on multiple devices, with unread message count sync across all devices
- Universal “conversations” that can be used to create one-on-one messaging, channels, public and private chats
- Messages are saved if user is offline and delivered when they are back online
- Push notifications support
- “Moderators” support
- “Typing” notification support
- Channels, users and messages can be edited
- Notifications for all event across all affected users
- Conversations and messages can be saved to and loaded from app storage
- Optimized for low cpu, memory and network usage
- Other messengers integration via HTTP API and callbacks
Getting started with Web SDK
Use the new Messenger singleton via getMessenger and createConversation/joinConversation API to access the Conversation object with a sendMessage method. Subscribe for different events to get notified when a conversation is created, new message arrives, new user joins a conversation etc.
Getting started with Android SDK
Use the new IMessenger singleton via getMessenger and createConversaton/joinConversation API to access the IConversation object with a sendMessage method. Subscribe for different events to get notified when a conversation is created, new message arrives, new user joins a conversation etc.
Getting started with iOS SDK
Use the new messenger singleton property via VIClient and createConversaton/joinConversation API to access the VIConversation object with a sendMessage method. Subscribe for different events to get notified when a conversation is created, new message arrives, new user joins a conversation etc.
Following Google’s release of new Speech API, we are happy to announce improved quality of call records transcription. No changes are required, your old code like will be producing more accurate results. In addition to that, you can now specify output format to get transcription in form of JSON file with timestamps for further processing. We are working on some examples that will be available in HowTo’s in the nearest future.
Screen Sharing allows you to share information on your screen during a call. You can share the entire screen or one of the active windows.
The best way to understand any functionality is to build a simple demo application. Let’s create a demo app that allows username1 to make a video call to username2 and, during the call, users can share their screen with one another. The demo app has three video blocks: the first one is for your own video stream, the second one is for the incoming video stream and the third one is for viewing locally what is being shared.
To simplify the process, we will use our video chat demo as a boilerplate. You can follow the link and copy whatever piece of code you want. So let’s do it!
We are happy to announce that video calls that use H.264 video codec can now be recorded. Recorded video calls that use H.264 will be stored as mp4 files (calls with video in VP8 format are stored as webm files). There are few ways to enable H.264 in your video calls:
– Use H264first Config param (Web SDK)
– Use H264first flag in CallSettings (Web SDK)
– Mobile SDKs are being updated to let developers enable H264 in video calls
According to the following research from Chris Koehncke using H.264 instead of VP8 can save up to 50% in terms of power consumption https://www.chriskranky.com/webrtc-impacts-on-battery-life/ , in addition to that mp4/avc is widely used and supported by most players in both online and offline worlds.
See the example of video recording below (Firefox->Voximplant, no post-processing)
P.S. Feel free to ping us if you have any problems with video call recording
We are happy to announce our new mobile SDK for Unity platform. Now Unity developers can use the SDK to embed real-time voice and video communication into VR/AR apps and games in minutes, we will take care of complexity and infrastructure. The SDK is compatible with Google Daydream. Please visit https://unity.voximplant.com/ to learn more.
Storing and saving passwords inside applications is not safe. For better security our SDK provides two additional login methods: with the one-time login keys and with the renewable tokens. Keys omits the need to store passwords entirely by using your own backend that will generate a one-time login key each time your application needs to login the Voximplant cloud. Although very secure, the keys require your own backend to be created, while the “tokens” can be used entirely on the SDK side with some security and usability trade-offs that are explained in this article.
VoxImplant push notifications for Android are based on FirebaseCloud Messaging (FCM) platform and implemented as the “data messages”. Using notifications, a device can be awakened and an app started before a call arrives. Our SDK requires Android API 16 (4.1), while push notifications support also requires Play Services 10.0.1 or higher to be available on the device. Our Android SDK contains a sample application with all the code needed to handle push notification. Following tutorial explains that code and describes additional steps that should be performed to have a working Push Notifications solution for your mobile applications.
Push notifications are available since Android SDK version 2.1.0
