I have an grandstream PBX in the cloud
I need to register asterisk in that PBX to make calls
Some times the registration is ok, sometimes is not working
This is the configuration
[USER]
type=registration
transport=transport-udp-nat
outbound_auth=USER
server_uri=sip:USER@GRANDSTREAM.COM:7160
client_uri=sip:USER@GRANDSTREAM.COM
retry_interval=60
expiration=120
contact_user=3021
max_retries=0
[USER]
type=auth
auth_type=userpass
password=PASSWORD
username=USER
[USER]
type=aor
contact=sip:GRANDSTREAM.COM
[USER]
type=endpoint
transport=transport-udp-nat
context=USER
disallow=all
allow=opus
outbound_auth=USER
aors=USER
from_user=USER
direct_media=no
Sometimes asterisk sends the first REGISTER, grandstream answers with 401 unauthorized and the nonce, but asterisk does not send the new register with the password
This is the full capture
