<br>Hi all,<br><br>I am testing the scenario described here: <a href="http://kb.asipto.com/asterisk:realtime:kamailio-3.1.x-asterisk-1.6.2-astdb">http://kb.asipto.com/asterisk:realtime:kamailio-3.1.x-asterisk-1.6.2-astdb</a><br>
<br>It works great with one instance of Asterisk, but now that I'm testing with two Asterisk instances to load balance, and I see a problem regarding the registration forwarding to the second Asterisk.<br><br>I tried adding a second "uac_req_send()" bellow the first one, but Kamailio only sends the first request and the REGISTER never gets to the second Asterisk:<br>
