I am attempting to create a registration/account-based trunk between a V20 3CX server and an Asterisk 20.6.0 server for sending dial codes to Bogen intercoms. I have been at it for a few days and have been unable to get registration between servers to work, although the user/pass has been verified to be correct. I am pretty close, but I keep getting an AOR error on the Asterisk side, which does not make sense since it is part of the configuration. 3CX randomly assigns internal extension numbers and, in this case, has assigned 10001, which I cannot change. Included are the Asterisk pjsip.conf config and sip logs, followed by the corresponding 3CX log for the same event. Thoughts?
Asterisk pjsip config:
[transport-udp]
type=transport
protocol=udp
bind=0.0.0.0
[acdc-mn-3cx]
type=endpoint
context=from-internal
disallow=all
allow=ulaw
aors=acdc-mn-3cx
outbound_auth=acdc-mn-3cx-auth
direct_media=no
transport=transport-udp
[acdc-mn-3cx]
type=aor
max_contacts=1
contact=sip:3CXPublicIP:5060 ; Specify the 3CX IP and port
[acdc-mn-3cx-auth]
type=auth
username=XXXXXXXXXX
password=8characterpassword
[acdc-mn-3cx]
type=registration
outbound_auth=acdc-mn-3cx-auth
server_uri=sip:3CXPublicIP
client_uri=sip:XXXXXXXXXX@3CXPublicIP
retry_interval=60
[acdc-mn-3cx-identify]
type=identify
endpoint=acdc-mn-3cx
match=3CXPublicIP ; Ensure this matches the IP of the 3CX server
