In my app ,I want to integrate Twilio chat, voice and video. For now I am working on Twilio voip. I have used this link to make call : https://www.ipragmatech.com/steps-make-call-android-twilio-voice/

but I am getting my app crashed with this error Logcat error:

Twilio evangelist here. I have a video that shows how to generate capability tokens for Twilio Video using Twilio Functions that might make this a bit easier for you. Check out the video here and where it creates a Video grant you can create a Voice grant using var grant = new VoiceGrant();.

For more details on generating capability tokens, check out the documentation here: https://www.twilio.com/docs/iam/access-tokens
