<br>
I know no recipe, since WAN failover means your IP is moved on to the<br>
standby connection when links are switched. If this is not the case what<br>
you have isn't really a WAN failover, but just two unrelated internet<br>
connections and a router balancing them with a failover logic.<br>
<br>
If the IP changes when the WAN link is switched there is no way the<br>
router, or asterisk or anything in your LAN can do to bring over<br>
existing connections.<br>
<br>
Asterisk using ICE will analyze the active connection at call time and<br>
insert SDP information pertinent to that one for the call. So it will<br>
work correctly for whatever link is being used as long as it is used.<br>
Active calls when the link is switched due to a failure on the main one<br>
will go mute and time out.<br>
<br>
As Joshua Colp stated, ICE needs the other party to also have ICE<br>
enabled to work correctly, so you also need collaboration from the other<br>
side of the communication.<br>
<br>
Maybe if you explain better what you have and what you are trying to<br>
achieve some better suggestion can be given.<br>
