Hi @jak67429
In default configuration, policy control rule blocked all of traffic from Internet except VPN/GRE/VRRP services.
If you would like to allow traffic from external SIP server to Internal SIP client. You can add policy control rule for your SIP server first.
e.g From: WAN, To: LAN1, Source: YourSIPServerIP, Destination: any, Action: Allow.
