SIP makes it easier... to find his way, especially if you have STUNT in the system
RTP is not and if you have dual NAT then it sucks

@rafamello

listen to the good advice from @chpalmer :
Would it be possible for you to bridge your modem and get your public IP address on your WAN?

++++edit:
VOIP, behind dual-NAT can take several hours for even a seriously trained IT guy too

I am seeing another environment that has this configuration for me to test.

@DaddyGo it's difficult, you will end up losing the customer.

@rafamello

do you write from Portugal or Brazil?

SIP ALG

now with the public IP on the WAN the IPBX support is claiming that the internal IP arrives, I believe that I would now have to do a nat out ... I already have the image in the will it be correct?

DaddyGo

@rafamello "Brasil"

this is a problem, because if you were corresponding from Portugal.....
then I know ISPs (MEO, NOS, Vodafone)here and I know how to create "modo -bridge"

-the easiest is if you can get a direct public IP on the WAN

if you can't do that then the RTP ports must be forwarded through the ISP router and pfSense and it will work

unfortunately, it is so difficult to help that we do not know your tools / devices or the specific connection system

@rafamello If their SIP packets have the private IP encapsulated then they won't be able to stream back to you. I'm not sure which it would be but it's either ALG or the double NAT. SIP doesn't really work with either.

When dealing with Cable operators in the USA (Spectrum and Comcast) there are 3 modes for the cable modems:

RIP with NAT = Use when you are not providing a separate router. You would never use this with pfSense or any other customer provided firewall/router.
RIP without NAT = Use when you have a static IP programmed in the router and the modem needs to be your Gateway.
Bridge = Use when you don't have a static and are providing your own router. This puts the Public IP directly on your firewall.
