[Blink] SIP PUBLISH failes with 400 Invalid auth header

[g4-lisz at tonarchiv.ch]

Hi there,

My SIP provider asked me to disable SIP PUBLISH on my Blink client.
Their system answers with "400 Invalid auth header", and as far as I
understand, their server will eventually drop the connection for DoS
reasons. (DoS with one request every 10 minutes??)

Now I wonder if auth headers can be enabled also for PUBLISH? And if
not, how can PUBLISH be disabled?

I'm using the Ubunut client V 5.1.3

Best regards
