Doorbell registration fails

[PKort]

Hi,

I am trying to get Asterisk up&running in my HA setup.
I have downloaded the Add-On and am attempting to get my video doorbell (HikVision DS-KV8113) registered.
I have setup new extension as per documentation:

cat /usr/share/hassio/homeassistant/asterisk/custom/pjsip_custom.conf

; Place your custom extensions here
[outgoing-flexisip]
type=endpoint
disallow=all
allow=ulaw,alaw
allow=h264
from_domain=192.168.0.2

[8000]
type = endpoint
context = default
disallow = all
allow = alaw,ulaw ; Audio codecs
allow=h264 ; Video codecs
direct_media_method=invite
dtmf_mode=info
callerid="Doorbell" <8000>
force_rport=no
aors= 8000
auth = auth8000

[8000]
type = aor
max_contacts = 1

[auth8000]
type=auth
auth_type=userpass
password=mypassword ; Set your password here
username=8000

I have configured the "Audo Add Extensions" option in the Add-On settings and setup Auto Add Secret to "mypassword".

I have person and user doorbell setup in HA with password "mypassword".

I have configured SIP in the doorbell:

with password = mypassword so I can get it running with any settings at all.
When I press "Save", I can see in the logs:

Can you please advise what are possible issues and what how they can be fixed?
