Thanks for your help.

Dear customer,

If IP direct call doesn't have latency, that means the cause of the issue is from the server side, because IP direct call doesn't need to communicate through the server.

Suggest you double check with your server provide and see where is the issue.
As I can see from the syslog, the invite message was sent, the server responsed after 7 seconds:

Any question, freely to let me know.
