Getting "Can't reach device id specified in the request" error while trying to supervise the call using Existing SIP Phone

We have registered out Existing Phone (SIP Phone) in service.devtest.ringcentral.com portal. After registration we got the device id that we are trying to use to supervise the call using that SIP Phone. But whenever we hit the https://platform.devtest.ringcentral.com/restapi/v1.0/account/accountId/telephony/sessions/telephonySessionId/supervise api we are getting the error "Can't reach deviceId specified in request". Also, after registration we have checked the status of Existing Phone and it is showing as Online. Please refer the screenshot below:

Is your "Existing SIP Phone" assigned to a user extension, who is a supervisor in the call monitor group?

Yes ...We have assigned the existing phone to the supervisor to monitor the call.

Can you make a voice call to the supervised extension (either to its direct number or via main company number * extension number) to see if your "existing SIP Phone" receive the incoming call and be able to connect to that call?

Or can you use the device id to make a call-out call programmatically?

Note: To avoid mistake, you don't need to specify the accountId when calling an API using the .Net SDK. The SDK uses the '~' tilde and the server recognize the account from the access token of the authenticated user.

Yes ..I am able to receive the calls on my Existing Phone number. As suggested, I also removed the account id from the api call but still getting the same exception. Also, I noticed that when we call the call supervision api using the Existing Phone Device Id, we get the missed call notification in the call logs.
