Hi,<br>
<br>
I've got my Kamailio script working, hurray! I had created SRV and
NAPTR records for the proxies but was missing a critical line in the
script:<br>
<br>
dns_try_naptr=yes<br>
<br>
This enables Kamailio to query the NAPTR and SRV records and then
decide on the appropriate traffic to talk to the other proxy for non
local calls.<br>
<br>

<br>
This was tough for a Kamailio noob like myself :-) I've put the
whole thing on my wiki in case anybody else would like to build a
federated SIP system.<br>

<br>
Thanks again for the help Daniel. I will update your wiki also,
(which I shamelessly ripped off), if you give me write access.<br>
<br>
Cheers,<br>
John<br>
