Dear Bogdan,

 

Thank you for your tips. I find the reason is firewall.

The rule of 5060 is not opened.

 

Thank you very much.

 

Best regards,

Charles

Hi Charles,

as the ngrep shows, the request is sent to the address where the
asterisk should be present - if the asterisk is really listening on the
correct IP and port, try to use ngrep also on the target machine to see
if the msg arrives. also check for ip rules / firewalls. Use netstat to
se if asterisk is really listening on the port you expect.

regards,
bogdan
