Why in-app Calls?

Beyond the engaging ways that chat has developed in the last 10 years, voice and video offer human presence, genuine emotion, and connection rivaled only by in-person interactions. Yet, in-app voice and video communication, like in-app chat, poses a significant technical challenge to development teams building a solution. High uptime, low latency server infrastructure, security, multi-platform support—all these aspects contribute to why companies seek vendors for user experiences and why we chose to meet our customers’ voice and video in-app calling needs.

Given our expertise in building a highly scalable and reliable chat infrastructure for some of the largest brands in the world, it’s a natural progression for us to deliver voice and video as part of the broader Sendbird interaction platform. Similar to chat, we deliver the power of these new capabilities via a simple-to-use API with straightforward pay-as-you-go plans, eliminating the need for a massive development and server investment on the part of our customers. In fact, we believe Sendbird Calls customers can get up and running with their first call in as little as fifteen minutes.

Voice and video interactions drive increased transactions across industries

Sendbird Calls enables the creation of a real-time, immersive, and personal interaction between two users. Whether your app offers users professional services, customer support, health & wellness care, dating or concierge services, a voice or video call adds a personal touch to high-value interactions.

In-app voice and video calls are perfect for:

  • Marketplace apps
    • Create interactions between buyer and sellers that bring products to life, or ensure that users coordinate exchanges without going off app
  • On-demand delivery & ride-sharing
    • In-app voice calls can be critical for resolving time-sensitive disruptions to any transaction as well as provide hands-free communication for drivers
  • Healthcare providers
    • Whether you’re doing telemedicine or tele-mental wellness, your experts can connect, be present, and communicate with patients in a medium that feels personal and supportive, and creates better patient outcomes and satisfaction
  • Healthcare benefits & administration
    • Communicate with users about often complicated and deeply personal issues related to healthcare benefits
  • Tele-professional services
    • If you offer financial, legal, accounting, tutoring or other professional services, you can deliver rich interactions from within your app or website
  • Concierge or Customer Support
    • Offer satisfying voice or video interactions for high-value concierge services and customer support, so you can resolve calls quickly and personally, and keep call logs associated with the customer account
  • Dating
    • Go beyond chatting by offering date seekers the ability to spent time with each other over an in-app call, while keeping their actual phone numbers private

Bringing voice and video calls to your app

Sendbird Calls offers immersive 1:1 audio and video within the context of your app and user experience.

Blog Voice and Video Calls

Voice and Video in the context of your user experience

No communication is initiated out of context. Rich voice and video interactions are only a click or a tap away when a user wants to buy a product within a marketplace, seek help from an expert, or connect with another person on a dating app.

With Sendbird Calls integrated into your app, you can embed any custom data into the call metadata to create a contextual experience for your users. So, for example, when a potential renter looks at five rental listings from a single agent and then calls them, in-app metadata can tell the agent exactly which rental listing the potential renter is calling about, right on the incoming call notification, and later in the call logs.. This level of custom metadata integration can deliver personalized and seamless communication directly to your users in ways that will give them a wow experience.

Multi-device support

App users are constantly on the move—from working at the office or traveling between meetings, to entering their car and arriving at home. A user may have different devices in all these places, so it’s crucial for voice and video communication to support multiple devices per user. Out of the box, Sendbird Calls supports unlimited simultaneously logged-in devices per user.

Beyond multiple devices, Sendbird Calls works on iOS, Android, and JavaScript, and supports making calls between devices running any of these platforms.


We hold Sendbird Calls’ security, privacy, and confidentiality to the same high standards as in our chat product.
