Hello im trying to replace the cisco router provided by our SIP provider to pfsense, because they billing us every month on the cisco router instead we come up with the solution to replace it with pfsense XG7100 1U.
but when i try to replace it with pfsense XG7100 1U unable to call either inbound or outbound calls from PANASONIC NS-300.

here is the SIP provider topology - WORKING!

Do a Wireshark capture of SIP traffic on the LAN and WAN ports on pfsense and see what is missing or being dropped

I am assuming there are some specific settings inside the Cisco that need to be added to pfsense.
