hmmm... so doing that will also require <span class="Apple-style-span" style="font-family: arial, sans-serif; font-size: 13px; border-collapse: collapse; ">X-Auth-IP, right or something more tricky can be done?</span><div>

It is, but it relies on the caller supporting 3xx. They might not<br>
handle the redirect.<br>
<br>
A lot won't because you could redirect them to anywhere, so lots of<br>
implementations will ignore the 3xx. FreeSWITCH for instance can<br>
either ignore a 3xx or will send the call back into the dialplan.<br>
<br>
I think you'll have more success having a FS server in front of the<br>
others and bridging the call through to each server. If you set<br>
inbound_bypass_media=true on the SIP profile, the RTP media will<br>
bypass that server and go directly between the caller and the other FS<br>
box. That means that the call won't be using any CPU since it'll only<br>
wake up when a SIP packet is being sent/received. You'll still be<br>
creating a session through so it'll still be allocating memory to the<br>
call, a SIP proxy would use fewer resources.<br>
