and when twiliovoice.register func what is device token??

[bobiechen-twilio]

Hi @aksh1995a

What do you see when you feed your Access Token into https://jwt.io ? The error code and message indicated that the header of the token was not incorrect. It should look like:

{
  "alg": "HS256",
  "typ": "JWT",
  "cty": "twilio-fpa;v=1"
}

(Note: please don't post any of your personal account credentials, including the access token, in the public forum.)

Are you using any of the Twilio server helper library for token generation and if yes, which one are you using?

The deviceToken for the TwilioVoice.register() method is the device returned in the pkPushRegistry:didUpdatePushCredentials:forType: callback: https://github.com/twilio/voice-quickstart-swift/blob/master/SwiftVoiceCallKitQuickstart/ViewController.swift#L146

hello , I am using the same auth token for tcdevice and tcconnection it works fine!outgoing calls and all,but unfortunately I am not able to get callsid from those methods so I have to integrate through twiliovoice but here the same access token I used for device gives me error.       Inside register:deviceToken:completion:, failed to register for Twilio push notifications. Error:Invalid access token and the same for twiliovoice.call 

Error Domain=com.twilio.voice.error Code=20102 "Twilio Error 20102" UserInfo={NSLocalizedDescription=Twilio Error 20102, NSLocalizedFailureReason=Invalid Access Token header} I made changes in the header then error code was changed to 20103 but it also had same description. -Akshay

Hi @aksh1995a

The Programmable Voice SDK requires a version of token that is different from the Capability Token used in the Twilio Client SDK. Please check out the Access Token page and update your token vending server endpoint.

Thanks -bobie

Hi @aksh1995a I am closing this ticket since there has been no activities for a while and assuming the original issue has been resolved. Please feel free to reach out to us if you run into any issue using the SDK.

Thanks -bobie

@bobiechen-twilio I am trying to integrate it in SwiftUI and i am getting an error while starting an outgoing call: Error Domain=com.twilo.voice.error Code=20102 "Invalid Access Token header" UserInfo={NSLocalizedDescription=Invalid Access Token header, NSLocalizedFailureReason=SIP/2.0 403 Forbidden}

I decoded the JWT Token and in header i see this: { "alg": "HS256", "typ": "JWT", "cty": "JWT" }

so what could be wrong in above token header? similar issue i posted here as well.

[bobiechen-twilio]

The cty (content type) should be twilio-fpa;v=1

[softsan]

@bobiechen-twilio Okay Thanks for the quick reply. Will check on my server side.

@bobiechen-twilio Confirming adjusting server logic fixed the problem. Thanks
