We have 18 SIP trunks with Flow Route. I am able to receive the 1st call inbound but the 2nd fails. Flow Route says they can see it hit the phone system but gets rejected. The IP's they are sending to the IPO is 22.214.171.124/28 so multiple IP's. The .32 IP works fine, just not the rest. The firewall is allowing traffic to the IPO as well. How do I allow the rest of the IP's to be allowed to receive calls? I have 1 default route and it is set to the firewall on the LAN.
