Problem with trunk configuration

Hello,

I have strange situation with pjsip trunk between two freepbx server. Lets call it server A and B for make situation easier. This is trunk config:

Server A:

Server B:

Config is the same on both sides. Only difference is an IP address.

On server A is installed freepbx 16 (applaince)
On server B is installed freepbx 17 (Debian 12)

Connection is not blocked by any FW or something like that.
When i am calling from extension registered is server B to extensions registered in server A everything works fine. But when I am calling in from A to B i see in logs this error:

[2024-11-07 19:51:15] ERROR[1371] res_pjsip.c: Endpoint ‘TrunkWBC’: Could not create dialog to invalid URI ‘TrunkWBC’. Is endpoint registered and reachable?
12873 [2024-11-07 19:51:15] ERROR[1371] chan_pjsip.c: Failed to create outgoing session to endpoint ‘TrunkWBC’

I checked logs on FW with is between this two servers and I cant see traffic from server A to B. It seems like server A dont tray to connect to server B at all.

I did not changed anything in Advanced tab in Trunk configuration on both servers
