Stale Nonce

[buendiya]

Hi
According to https://tools.ietf.org/html/rfc5389#page-27.

If the response is an error response with an error code of 438 (Stale
Nonce), the client MUST retry the request, using the new NONCE
supplied in the 438 (Stale Nonce) response.

I can't find implementation about this in code.

I am using coturn as turnserver. The default nonce lifetime is 600 secs. It will raise a Stale Nonce TransactionFailed after 600 secs.

Is there a public server where I can test this?

From reading the RFC I'm not sure I can tell the difference between the handling of 401 or 438 status codes. It seems in both cases the NONCE and REALM attributes need to be updated?

I am tempted to handle both cases here:
