I suppose I am putting the cart before the horse so to speak. I have started verifying my NAT configuration is correct, as it is not what I am used to. Eventually I was able to make a call. Here is the configuration in case any one encounters the same frustration I had:
LAB-ADTRAN-908e#sh run int ethernet 0/1
Building configuration...
!
!
interface eth 0/1
ip address xxx.xxx.xxx.xxxx 255.255.255.224

end
LAB-ADTRAN-908e#sh run int ethernet 0/2

end

The outstanding question:
==========================================================================================
I can see what this configuration is doing. It is a proxy. I have never done with before, and would prefer not to. I would prefer the Adtran 908 serves as a PBX, where internal LAN extensions are translated to share the same outgoing number. I am coming from CME world. In CME world this is what I commonly do:
voice translation-rule 1
rule 1 /.*/ /xxxxxxxxxx/ <= ASSIGNED NUMBER FROM METASWITCH GROUP
!
voice translation-rule 2
rule 1 /.*/ /299/ <=HUNT PILOT NUMBER
voice translation-profile META-TRUNK1-INBOUND
translate called 2
!
voice translation-profile META-TRUNK1-OUTBOUND
translate calling 1
dial-peer voice 100 voip
