FreeSWITCH SIP Proxy configuration

I have a freshly installed "FreeSWITCH", and I want to configure it with the below example: The "Outbound Traffic" - Accept the SIP traffic from the Local "A" ([login to view URL]) SIP Server. - Redirect the Signaling to the Local "B" ([login to view URL]) SIP Server. - If the Signaling response is accepted, the traffic (Signaling and Media) will be redirected to the Local "C" ([login to view URL]) SIP Server. The "Inbound Traffic" - Accept the SIP traffic from the Local "C" ([login to view URL]) SIP Server. - Redirect the Signaling to the Local "B" ([login to view URL]) SIP Server. - If the Signaling response is accepted, the traffic (Signaling and Media) will be redirected to the Local "A" ([login to view URL]) SIP Server. All the traffic mentioned will be on the local network and should be over 5060/UDP. NOTES: - Please don't waste the time if you're not an expert in the FreeSWITCH, Thank you. - Bot bidder will be reported.
