[Solved] Multi-Wan Fail-Over & VOIP
«

We have daily power blackouts for 2&half hours in South Africa.
When the blackout happens our primary ISP is also going down after about 2 hours into the blackout.
Fail over works as intended for all services from WAN1 to WAN2 except for VOIP.
WAN2 is a pay as use LTE service
It seems that the Firewall is blocking VOIP services on WAN2. Nothing is shown in the Live View that the source IP address or SIP port is blocked. The Live View does show the following Allow Rule on WAN2
xxx.xxx.140.140:5060 udp let out anything from firewall host itself (force gw)
Firewall/Settings/Advanced/Sticky Connections is off
Firewall/Settings/Advanced/Shared Forwarding is on
Firewall/Settings/Advanced/Bind States to interface is on
Firewall/Settings/Advanced/Dynamic States Reset is on
WAN1 is set as Tier 1 and WAN2 as Tier 2 on Member Down
Any advice how to get VOIP to switch over from WAN1 to WAN2 automatically when WAN1 is going will be highly appreciated.

Hi,
Is it not your operator who blocks VoIP with a data subscription?

Darkopnsense, thanks for pointing me in a new direction.
VoLTE on the router was ON, change to OFF and VOIP Fail-Over to WAN2 is successful
