Hi @Jehad Jawad

I am not sure if it could be completed. But it requires you need to meet the following situation below.

Local Media Optimization supports two scenarios:

• Centralization of all local trunks through a centralized SBC connected to the main Session Initiation Protocol (SIP) trunk--providing telephony services to all local branch offices of the company.
• Building a virtual network topology of SBCs--where the SBCs in the local branch offices are connected to a centralized proxy SBC that is visible to, and communicating with, Microsoft Phone System through its external IP address. In a virtual network topology, downstream SBCs are communicating through internal IPs and are not directly visible to Phone System.
