Unable to receive calls on Android phones whilst utilizing the LTE Network Extender our business was provided. Restrictive firewall was adjusted from the following KB: https://www.verizon.com/support/knowledge-base-25525/#NE1

iPhone's work like a champ. If I create an allow any any rule for the LTE NE calls come into the Android phones...

Firewall blocks 141.207.160.227:500 but it's in the FQDN sgw.vzwfemto.com 

FW rule looks like this:

TCP/UDP Ports open:

123, 500, 4500, 20906, 52428

Addresses Open: 

sg-4g.vzwfemto.com, sgw.vzwfemto.com, gps.vzwfemto.com, cmp.securitycredentialing.com

Do the firewall logs show/identify the traffic to the Android phones being blocked?  What about when the Android calls do come in with the firewall open, are you able to do a packet capture to see what the difference in the traffic is?

My questions were for poster @borg7 regarding their troubleshooting, not @vzw_customer_support of which NO agents have responded to the original post.
