Connect 3CX and Asterisk

[amart]

Hello,

I follow this tuto :
https://www.3cx.com/docs/
But my bridge doesn't work.

My primary server is an Asterisk with freePBX.
My 3CX is a second server (trial version for testing solution).

My sip.conf on Asterisk :
- Outbound (trunk name: 3CX_peer) :

host=IP_3CX
type=peer
username=ID_user
fromuser=ID_user
secret=PASSWORD
context=from-trunk&from-ovh
qualify=yes&yes
insecure=invite&port,invite
srvlookup=yes
;dtmfmode=inband
dtmfmode=rfc2833
disallow=all
allow=alaw&ilbc&ulaw

- Inbound (user context : ID_user) :

host=IP_3CX
port=5060
type=peer
trustrpid=yes
context=from-trunk

-Registration String:

ID_user:pASSWORD@IP_3CX/ID_user

My Bridge config on 3CX :

Type : Master
Name : ID_user
ID : ID_user
secret : PASSWORD

Test
I tried with a slave bridge, and a trunk to Asterisk and doesn't succeed.
I change many time the registration string with and without port number (5060) :

ID_user:pASSWORD@IP_3CX/ID_user (actual)
ID_user@IP_3CX/ID_user
ID_user:ID_user@IP_3CX/ID_user (actual)

When i do a "sip show peers" : My outbound is OK and my inbound is "unmonitored.
But with a "sip show registry i juste have a "Request send" to @IP_3CX

Firewall doesn't block traffic, with tcpdump i see packet (in the buttom of message).
When i capture traffic with tcpdump (on router), i see :

13:31:40.618209 IP IP_3CX.sip > IP_Asterisk.sip: SIP: REGISTER sip:IP_Asterisk:5060 SIP/2.0
13:31:40.628339 IP IP_Asterisk.sip > IP_3CX.sip: SIP: SIP/2.0 401 Unauthorized

13:32:41.674531 IP IP_3CX.sip > IP_Asterisk.sip: SIP: SIP/2.0 200 OK

When i show packet , i sew sometimes a "unknow user" with an ID deleted 1hour ago (i checked my sip.conf and this user ID is really deleted)

When i refresh status of bridge on 3CX, i see this message on Asterisk :

2019-07-04 15:37:54] NOTICE[55631]: chan_sip.c:27741 handle_request_register: Registration from '<sip:ID_user@IP_Asterisk:5060>' failed for 'IP_3CX:5060' - Wrong password

I think the problem is my Asterisk can't connect to 3CX, Do you see any error on my configuration ?

I change the inbound config on my asterisk :
host=IP_3CX > host=dynamic

My 3CX is now registred to Asterisk, but i still have this error when my Asterisk try a register message to 3CX
