Issue
Change of IP to SIP SBC causes one way speech for outbound calls. SDP shows internal IP on call setup

Solution
Force the deployment to use fixed addresses in topology, publish. Then remove this (remember to visit the PSTN gateways tab) publish.

You should have no IP’s set when running 

get-csnetworkinterfaces for PSTN
