mentioned, it was discussed for FS, but it’s a LOT of work to get that state synchronized.

<p>Can you comment some more on how this is configured?</p>

<p>Would it be something that could be added to the wiki in the
SBC setup page?</p>

<p style="margin-bottom:12.0pt">I've experience with a
commercial SBC, these are two machines running in cluster mode. In that case if
one SBC is going down then other will take all new calls including the call
which were active on broken SBC (SIP only). <br>

Thats quite ideal for wholesale traffic where the SBC will never be idle. </p>

<p>Yes I'm sure much of their software can do this but it has
been set up for<br>
static numeric IPs. And getting the IP changed is a week-long process for<br>
some customers!</p>

<p>Yes and I don't want to touch established calls - those
calls can stay<br>
there until they drop. This is sent to new requests when<br>
switch_core_session_request fails in mod_sofia.</p>

<p>Some are broken. Some just have this feature disabled. For
'security<br>
reasons'. You know the drill.<br>
