Hi ppl, Noticed BYE requests relayed from caller to callee have the *Proxy-Authorization* header including *Digest*, *nonce* and *response*. Is that by SIP definition or am I doing something wrong? My concern is the callee gets to see caller's authentication credentials. Thanks.

You can remove all unwanted headers from in-dialog requests using remove_hf function. -- Juha

Hi Aqs, By all means I'm doing that for dialog-forming INVITEs, just in doubt if need (or not) to do the same for other methods that carry authentication headers. I now found this article which partially explains my dilemma. https://stackoverflow.com/questions/14066587/sip-getting-407-response-for-b… Cheers.

Some update. I'll have to see in time if this is ok, but for now * remove_hf("Proxy-Authorization")* in a *if (from_uri == myself && has_credentials("mydomain"))* statement WITHINDLG route seems to do the trick. *consume_credentials()* for some reason doesn't on in-dialogs.

After authentication, you always need to consume the credentials, as pointed out. There’s a function specifically for that. Check out the default-installed config, you’ll see it being used there. David On Sat, 18 May 2019 at 17:08, Sergiu Pojoga <pojogas(a)gmail.com> wrote:

Hi David, Not sure if you read the entire thread, the question was specifically for in-dialog subsequent requests. Even in the default config, *route[AUTH]* is right after *route[WITHINDLG]*, so I highly doubt re-Invites, BYEs and other in-dialogs are stripped of authentication credentials. Correct me if I'm wrong. Cheers. On Sun, May 19, 2019 at 7:41 AM David Villasmil < david.villasmil.work(a)gmail.com> wrote:
