How would you explain the carrier tenant to anybody that asks?
Would I be right in saying this is just a management point for the direct routing SBC in the MS cloud?
I understand how it is configured and we have this working. I understand it is also used to check the domains registered with the certificate presented for MTLS.
If for any reason the carrier tenant went down or wasn't available would this affect calls? I am assuming not as its not involved in any call flows and the connectivity is between our on-premise SBC and the MS SIP proxies\transport relays.
