Hi,

Since 2 weeks, i'm experiencing lot of troubles with my VoIP services : it sticks on the failover device (4G modem), even when there is no problem with the main connection. All other connections are using the main link, but the VoIP service is not... And is not working as well.
I'm using this configuration since month's without problems, and updated to 3.8.0 one month ago. Is there any issue with internet failover on this version? Something changed? Is there any differences between x86 and x64 versions?

Thanks

Try a previous version, and see. I did not have issues with 3.5.0 while I still used load balancing configuration.

We use load balancing with balancing rules routing SIP traffic to a preferred gateway. When it fails a new one is chosen, but while UDP NAT sessions are alive on the new gateway, it is used regardless the status of the preferred one.

The only way to switch your gateway back is to let NAT sessions expire (turn SIP user agents off) or manually disable the new gateway. I guess it does not happen with http connections because their lifespan is shorter, while UDP ones could last forever.
