Is your device registered? What is the console output?

Hello, there isnt any registration. it is only ip auth.

endpoint:  kaa                                                 Unavailable   0 of inf
        Aor:  kaa                                               0
  Transport:  notsimple                 udp      0      0  172.20.12.186:5060

        Match: 172.20.25.99/32
        Match: 172.20.25.35/32

That would be why. There is no contact on the ‘kaa’ AOR. It has no knowledge of where an OPTIONS would be sent. You can add an explicit one using the contact option, such as:

contact=sip:172.20.12.186

hello, it is work.
Thanks

it is last conf. to help others.
