Explanation

For maximum resilience with location-based call routing across two offices, you need both redundancy at each site and policy-based routing. Deploying a highly available SBC pair at each office (B) ensures that if one SBC fails, its partner handles calls without service interruption-a single SBC per office (A) creates a single point of failure. Configuring voice routing policies per office (C) ensures that Paris users route their calls through the Paris SBCs and London users through the London SBCs, meeting the requirement that calls route through each user's respective office. A single voice routing policy for all users (D) cannot distinguish between office locations and would not enforce site-local routing, which could route calls inefficiently or through the wrong carrier connection.
