Hey, kamailio is addictive - there are quite some of us doing it on
Sundays ;-)

I've just checked the manual, it says kamailio, not asterisk should do
authentication of REGISTERs. Could you check you have created sipusers
table and configured asterisk as per manual:

sipusers is the standard table required by Asterisk to store SIP user
profile, with one extra column sippasswd where will be stored the
password for SIP authentication. By default, Asterisk uses the column
secret for SIP user password, but if that is filled in, Asterisk will
ask for authentication again, resulting in double-authentication which
we want to avoid.
?

OMG…right under my nose the whole time. I love this stuff! ;)

I must have read and re-read the asipto guide a thousand times and googled until my fingers seized up, but I completely missed that … lol

So, in case anyone else comes across this same problem and you’ve followed the guide 100% you are undoubtedly looking for the “trick” to “configure Asterisk to not authenticate SIP requests coming from Kamailio”. Well, there’s no trick. Just slow down and read again. If that doesn’t work … do this:

For each Asterisk extension - set host=dynamic, secret=<blank> and permit=<kamailioip> then put the device password into sippasswd field in db. Kamailio will authenticate the device with sippasswd in db and route[REGFWD] will pass the registration to Asterisk. Since there is no password for secret, Asterisk will register the extension to kamailio.ip:port automatically. Because permit =< kamailioip > Asterisk will ONLY accept registration from Kamailio for the extension. You may want to set permit =< kamailioip > in sip.conf general section to set ACL for all extensions to make life easier.

My particular problem was that I did not delete the secret. This apparently causes Asterisk to request authentication from Kamailio on registration FWD.

Thanks Andrew, sometimes it just takes another person to ‘say it out loud’ lol
