The calls started after we upgraded Wimax to LTE, so we suspect it is something 
in our LTE setup.

Someone suggested we try DMZ, we are giving that a try.

Subject: Re: [AFMUG] Verizon WiFi Calling on Telrad LTE

 

Double NAT VZW wifi calling is working for me pretty regularly.  It's had quite 
a lot of improvements over the last few years, but it's good enough that I can 
say it "works OK".  My primary complaint is that if I have 1x 1 bar and it 
thinks there is connectivity, it won't even bother with WiFi calling.  It'll 
just fail in attempting the mobile network.

 

Are 100% of your customers on Telrad having this problem and 0% errors 
elsewhere?  Are you certain it's limited to Telrad?

In my experience, Verizon WiFi calling gets broken from (1) Double NAT, and (2) 
fragmented packets.

Customers with a Verizon cell phone using WiFi calling are unable to get calls 
in or out on our Telrad LTE network. Anyone else come across this problem? 
Ideas? Fix?
