are some on this list who do.</FONT></SPAN></DIV>

<DIV><SPAN class=770215123-29072006><FONT face=Arial size=2>I have been using
SIPBroker for dialing with sip codes only so far and did my enum lookups on my
own. But now, I decided to set ser up to try sipbroker first for all external
calls and then fall back to my different gateways if no route can be found
via SIPBroker.</FONT></SPAN></DIV>

<DIV><SPAN class=770215123-29072006><FONT face=Arial size=2>I send an Invite for

route for that number to another voipprovider it will proxy the call to the

sipbroker can not find a route, it will reply with a redirect of the call

my gateways.</FONT></SPAN></DIV>
