Hi all.

Please share your experience.

If you ever tried authenticating outgoing calls with Kamailio, did it work for you?

Which devices or servers you know do/don't accept such authentication?

Do you use it in some tricky way to get it working?

I wouldn't rely on it as it doesn't increase the CSeq so the new INVITE with credentials would be rejected/dropped by many devices/servers.

indeed it does not increase the cseq, however, you can solve it via script logic: - htable to keep relation between call-id and cseq incrementation - for each transaction where you have to update cseq, add the receving value in an avp to restore for reply, then update cseq value with offset from htable - sent and if you are challenged, increment the cseq offset in htable

In case of restart and you can use a trick like: if it is a request within dialog (has To-tag) for a call that could have been exposed to auth, then increment cseq by 10-20 or so, within a call are not so many auths (usually for re-invites).
