Hello,

pointed in another response, is_method(...) is good solution, I just wanted to add that you should be careful with what you reject and when, because part of an INVITE dialog can be more than just ACK, BYE and CANCEL, you can get REFER, UPDATE, INFO, NOTIFY...

So I would allow all requests that have a To-tag (see has_totag() and Route header added by kamailio (loose_route() should return true).

Hi,

I want to limit Kamailios accepted methods to REGISTER, INVITE and their related methods like BYE and CANCEL. How to do this in Kamailio? Is there a standard way or I should use is_method function?

Regards
