Hi @Ian ,  
i m implementing it in iOS, i am using VOIP notifications and unregistering VOIP Push tokens on logout, still i have to use SendBirdCall.unregisterRemotePush ?

```auto
 func deauthenticate() {
        
        print("deauthenticate appdelegate")
        SendBirdCall.deauthenticate { (error) in
            guard error == nil else { return }
            
            if let dataToken = UserDefaults.standard.voipPushToken as? Data {
                SendBirdCall.unregisterVoIPPush(token: UserDefaults.standard.voipPushToken, completionHandler: nil)
            }
            else {
                SendBirdCall.unregisterVoIPPush(token: tokenVoip, completionHandler: nil)
            }
            print("Successfully deauthenticated from SendBirdCalls")
        }
    }

```

Hi @Android_MR_Firebase , Sorry for the late response.

You should call `SendBirdCall.unregisterVoIPPush` before you call `SendBirdCall.deauthenticate`. Can you try this and see if the VoIP Push stops?

Hi @mininny

i tried the above, it fixed the issue, now i am not getting any VoIP push after logout, but i am getting another issue when i followed the above, When i logged in again now i am not getting any VoIP notification.

Here is the code snippet for both login(Authenticate) and logout(Deauthenticate)

For Login

```auto
//MARK: - Authenticate the user
    func authenticate(callerUserId: String) {
        
        let authenticateParams = AuthenticateParams(userId: callerUserId)
        SendBirdCall.authenticate(with: authenticateParams) { (user, error) in
            guard let user = user, error == nil else { return }
            
            SendBirdCall.registerVoIPPush(token: tokenVoip, unique: true) { error in
                guard error == nil else { return }
            }
            
            print("Successfully authenticated with userId: \(user.userId)")
        }
    }

```

For Logout

```auto
//MARK: - Deauthenticate User
     func deauthenticate() {

         if let dataToken = UserDefaults.standard.voipPushToken as? Data {
             SendBirdCall.unregisterVoIPPush(token: UserDefaults.standard.voipPushToken, 
             completionHandler: nil)
         }
         else {
             SendBirdCall.unregisterVoIPPush(token: tokenVoip, completionHandler: nil)
         }

        SendBirdCall.deauthenticate { (error) in
            guard error == nil else { return }
      
            print("Successfully deauthenticated from SendBirdCalls")
        }
    }

```

Hi @Android_MR_Firebase

try with below method

func deauthenticate() {  
if let dataToken = UserDefaults.standard.voipPushToken as? Data {  
SendBirdCall.unregisterVoIPPush(token: UserDefaults.standard.voipPushToken) { error in  
SendBirdCall.deauthenticate { (error) in  
guard error == nil else { return }  
print(“Successfully deauthenticated from SendBirdCalls”)  
}  
}  
}  
else {  
SendBirdCall.unregisterVoIPPush(token: tokenVoip) { error in  
SendBirdCall.deauthenticate { (error) in  
guard error == nil else { return }  
print(“Successfully deauthenticated from SendBirdCalls”)  
}  
}  
}  
}

after logout check Sendbird Dashboard user token is remove or not and after again login and check register new token
