Wondering if Sophos can deal with this issue.
I had and had to make a custom script for my pfSense firewall. I was in a situation where you have multi-wan with cloud voip phones. In the event that the primary wan went down and the phones disconnect they would switch to the secondary connection perfectly. The problem is when the primary came back up the phones would still hold a connection via the secondary but because of routing the phones would also try to make a connection via the primary resulting in the phones ringing but unable to hear the other party. The only way to resolve this was to kill all the states on the voice network/vlan still connected via the secondary when the primary would come back up allowing the phones to make a proper connection only via the primary ISP connection. I would have to do this manually until I was able to create a script for the pfsense firewall. Does the sophos have a mechanism for dealing with this scenario?
