Disabling SIP ALG on Verizon G3100 router

I am currently working from home using a Polycom phone hooked up via ethernet to a G3100 router. Some calls have not been getting to me and the it guys indicate that it is because SIP ALG is enabled on port 5060 of my router. I read through the manual and look at the router interface and did not see any place where the SIP ALG could be turned off. My questions are:

Can SIP ALG be turned off on the router and if so where?

Can VZ turn off SIP ALG server side?

Can I use port triggering to send the SIP traffic to port 5062 to get around the ALG?

Thanks

The option to disable SIP ALG is not currently available on Verizon routers.

If you have a single VOIP phone, you can try to enable the DMZ host from the Firewall section of the G3100 GUI - set the IP to the phone's IP. This solved my VOIP phone problems. Let us know if it works.

What about trying to use more than one iPhone to use wifi calling? Seems it auto connects and shows its connected to wifi calling at the top left of the iPhone, and sometimes its just not there unless I force airplane mode ?

VoIP is not officially supported by Verizon. G3100 and G1100 only has features that are requested by Verizon, so they would be constrained to the features necessary to deliver the FiOS service.

It is typically advised for business customers and residential customers who would like to use VoIP to use their own router. If you have multiple VoIP lines, I suggest you to buy a router capable of hardware DMZ, not only software DMZ.

Thanks for the reply!

sometimes wifi calling is connected on the iPhone and sometimes not. Is it doing so due to Verizon not supporting the VoIP service? Meaning, if it's not supported, should it not connect at all? or is that the reason it does, then disconnects...?

Also, if I DMZ route one iPhone, then wifi calling should stick since it is bypassing the verizon routers blocks?
