i have figured out the ht503 doesnt have Denmark as an option in its slic settings, but apparently norway has the same specs according to
so i set the ht503 up with
slic: norway
caller id scheme: etsi-dtmf
vocoder:ilbc
and in asterisk:
;===============TRANSPORT
[simpletrans]
type=transport
protocol=udp
bind=0.0.0.0
;===============EXTENSION 6001
[803995629]
type=endpoint
context=from-internal
disallow=all
tone_zone=dk
dtmf_mode=rfc4733
allow=ilbc,ulaw,alaw
auth=auth803995629
aors=803995629
[auth803995629]
type=auth
auth_type=userpass
password=895948852
username=803995629
[803995629]
type=aor
max_contacts=1
but it still doesnt work.
the connected phone is simply not showing any life and i have tested it multiple times on the landline where it works
i am thinking if the ht503 simply doesnt work in denmark as i feel i have exhausted all possibilities software and hardware wise to make it work
