I finally set up an st500 behind an NEC 2100 system and it connects but I have no audio either way any suggestions?

 
Ports would be my first check. Voice ports 10020-10531 need to be opened. If over wifi or cellular, ensure router does not have SIP ALG turned on
 
check if you put IP on 84-26-01
Make sure it's in the same subnet as the address in 10-12-07. And no conflicts. Both need to be static addresses.
