VoIP Profile configuration

Hello everyone

We have Local VoIP Server which must access our SIP Providers which have Public IP addresses

We have two firewall policies for outgoing and incoming traffic 

1. Allow our local VoIP Server to public SIP providers (NAT Enabled) for registration
2. Allow our public SIP providers to our local VoIP Server (Virtual IP)

We want to know on which policy we must apply VoIP Profile with strict-register enabled

Thank you!
