<div dir="ltr"><br><div>A little progress on this; the double-AOR problem was fixed; I had callbackextension field in the realtime table, which caused extra REGISTER messages to be sent from Asterisk to Kamailio and that messed the AORs for my clients. </div>
<div><br></div><div>Calling between the clients is a problem though, the INVITE gets routed correctly but for some reason, when the INVITE is returning from Asterisk to be routed to the called party, location lookup fails. I end up with 404 and no route to destination error. Any clues on to why location lookup would fail? </div>

<div> Expires: 3600</div></div><div><br></div><div><br></div><div>Currently I can make calls from 770 to 123 which is an Asterisk extension that answers, plays hello world and hangs up. However I can't call another sip clients when I route calls through Asterisk, they do work fine if I don't use Asterisk for handling calls, but I'd like Kamailio to be in the role of proxy/loadbalancer and Asterisk to handle calls. </div>
<div><br></div><div>My config is the simple default config, added with realtime stuff and then dispatcher according to the documentation. I wonder if there's something wrong in the REGISTER that Kamailio sends to Asterisk, or maybe something else going wrong?</div>
