So for clarification, Asterisk (ASL) uses ports 32001 and 34001 back to USRP to bridge correct?  

I showed DVSwitch at both points as one is using USRP (with port #'s), the other is using (iaxclient) as entrance points. (OPTIONS)  For what I am doing now, I am using only the USRP direct into the Analog Bridge.
