Migrate S4B on-prem to Teams Direct Routing; setup auto-attendant
Following scenario: Linked my AudioCodes M1000 SBC with Teams Moving accounts from On-prem to Teams. accounts have a 10 digit extensions: 444-123-3xxx some accounts have US DID's, which my SBC manipulates the routing for to change header from the DID to the 10digit extension, and send calls to Teams we have auto-attendant on S4B on-prem, using US toll free number. this is is all working fine. my Team's users can make outbound calls through the SBC, and we can receive inbound calls for the accounts that have DID's. However, my auto-attendant and receptionists are on S4B on-prem. How do I migrate my auto-attendant to Teams? I don't want to port my Toll free # to Microsoft. Currently, I believe, Direct Routing does not support "service" numbers. so how do I setup auto-attendant on Teams to work with our Toll-free number that is assigned to the SIP trunk that connects to my SBC?
