I believe it's not all carriers as I had some one just call me with a mobile (Bell) and he got through.
If it is Rogers(Fido) that's causing me grief, what should I do?
I suspect the steps I outlined previously should help address the problem, provided you are getting true bridge mode to your router.
What is the brand and model of the modem being used?
If it's a Bell or Virgin Hub, do PPPoE login using your router. This is called PPPoE passthrough.
You will need the PPPoE username and password from your ISP.
Some ISPs only allow one PPPoE login, but Bell, Virgin, Teksavvy, and Start allow multiple PPPoE logins. I avoid any ISP that only allows one PPPoE login.
Bottom line is that you need true bridge mode or PPPoE passthrough if a modem/router combo, hub, or gateway was provided by your ISP. These are not pure modems; they are combo devices that include built in routers, and the router features inside them can cause problems if they are not bypassed.
For Rogers, visit

Shaw users will have to call Shaw to enable bridge mode at the time of this post.
And then make sure SIP ALG is off (Siproxd) in your own router.
To understand why SIP ALG often causes horrible problems, please visit
https://www.voip-info.org/routers-sip-alg/ (scroll down to the section on SIP ALG problems).
Also, don't use VLAN.
A number of people using Asus routers have had to disable SIP Passthrough, which is the setting for SIP ALG in Asus routers, to get incoming calls from Rogers working with Freephoneline:

I believe this is the exact same issue caused by either SIP ALG (Siproxd in pfsense) or not getting true bridge mode (or using PPPoE passthrough) from the modem/router combo being used.
Fongo uses a third party vendor for its switches, and they appear to have made configuration changes at the switches.
Not using bridge mode (if a modem/router combo, hub, or gateway is being used in addition to another router) with SIP ALG enabled didn't matter as much before in some cases. It does now.
Rogers numbers have no issue calling me on my FPL accounts, but I'm not using pfSense. And the modem/router combo issued to me by my ISP is in bridge mode. SIP ALG is off in my router.
