Cool thanks Lonnie. Actually I can just add this in my routing table startup
script as this route will not go anywhere else.
I thought there was something a little more tricky at work!

Yes, as long as you trust your SIP provider will always echo ICMP, that is
not a bad solution. And as a side-effect it will failover when your SIP
provider is not reachable.
If you want a more general method, create a /mnt/kd/wan-failover.script ...
Failover Action Script
https://doc.astlinux-project.org/userdoc:tt_wan_failover#action_script_optional
**Untested example**
-- /mnt/kd/wan-failover.script --
#!/bin/sh
##
## wan-failover action script
##
## Automatically called after any WAN link change
##
state="$1"
primary_if="$2"
primary_gw="$3"
secondary_if="$4"
secondary_gw="$5"
secondary_gw_ipv6="$6"
primary_only_routes="1.2.3.4 1.2.3.5 1.2.4.0/24"
case $state in
SECONDARY)
## Switched to Failover using secondary WAN link
for x in $primary_only_routes; do
ip route add $x ${primary_gw:+via $primary_gw} dev $primary_if
done
;;
PRIMARY)
## Switched back to normal using primary WAN link
for x in $primary_only_routes; do
ip route delete $x ${primary_gw:+via $primary_gw} dev $primary_if
done
;;
esac
exit 0
--
This will add routes via the primary interface on failover you want
unreachable, and remove them when back to normal to clean things up.
