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).
Cheers,
Daniel
