If I understood the scenario, the Path header is not useful -- that's for the case when there is a proxy between UA and registrar server. In this scenario seems to be the UA using alternate registrars, either by DNS or configuration.

A solution is this case is to sync the two Kamailios A and B, so they accept the auth challenges generated by the other one. See:

Path header == Record-Route for REGISTERs.

Hi to all,

In a scenario, we need to change the destination of users' registration requests when they send the first 'Register' to Kamailio-A and it replies 401 to the user, next time the user sends 'Register' to Kamailio-B.

User------Register-------> Kamailio-A

User<-----401--------------Kamailio-A

User-------Register--------> Kamailio-B

RFC says we can't use the Record-Route for register because it doesn't create a dialog.

Is there any option, header that Kamailio-A puts in the 401, and after that users send register to the Kamailio-B?

Thank you.

BR,

Hossein
