all bold items and non-bold items match exactly just no ip address is received/given to the Dialer1 interface. 

debug ip packet log still shows encapsulation failed.

maybe this configuration is not supported by service-provider, Verizon for FiOS service?

Hello,

 

save the configuration (wr mem), then reboot the router. Also, post the running configuration just to check if everything is correct...
