How to connect asterisk to linksys spa400

I have a problem with an asterisk connection with linksys spa400
Can someone help me
This is the script I created:
pjsip.transports.conf
[0.0.0.0-udp]
type=transport
protocol=udp
bind=0.0.0.0:5060
allow_reload=yes

[mytrunk]
type=endpoint
context=from-internal
disallow=all
allow=ulaw
outbound_auth=mytrunk
aors=mytrunk

;Note: ini gunakan untuk call dari exten voix ke exten yeastar
[mytrunk]
type=registration
outbound_auth=mytrunk
server_uri=sip:10.10.12.234:9000
client_uri=sip:9000@10.10.12.234:9000
retry_interval=60

[mytrunk]
type=auth
auth_type=userpass
password=7890Nn
username=9000

[mytrunk]
type=aor
contact=sip:202.162.192.239

[mytrunk]
type=identify
endpoint=mytrunk
match=10.10.12.234

its error message
[Aug 21 14:41:19] WARNING[6960]: res_pjsip_outbound_registration.c:761 schedule_retry: No response received from ‘sip:10.10.12.234:9000’ on registration attempt to ‘sip:9000@10.10.12.234:9000’, retrying in ‘60’

Is the device at 10.10.12.234 actually listening for SIP traffic on port 9000?

yes jcoip
oh ea
Do you know how to connect between yeastar TA810 with asterisk?
Ip -> port
Port -> ip / port

I have no knowledge of that device.

I am attaching some configuration links.
I hope they serve you.
