Teams doesn't reply ACK for 200 OK
Hi, My SBC domain is sbc.portsip.io and resolved to 218.76.62.10, the SBC private IP is 192.168.0.11, and the TLS transport is 5078 for communicating with Teams, and used port 5069 on TCP for communication with backend PBX. When I dialed from teams, and the PBX extension answered the call, SBC send the below 200 OK to teams, voice is good but the teams is not replied ACK to SBC cause the call is hangup after a while, where is wrong?

Hi Andres, I have read that, but this is not meets my requirements. We have large users, we need load balancing for the SBC cluster, and we also need the solution for this scenario: a UCaaS tenant has more than 50K users, for communicates with Teams, a Single SBC can't handle it, so how the SBC cluster load balancing for this large tenant?2.9KViews0likes0CommentsConfigure multiple SBCs for teams multiple tenants
Hi, I'm running a UCaaS platform. To support large users of teams clients with direct routing, I will need to set up an SBC cluster(multiple SBCs) for teams multiple tenants, how can I configure it? I've read this guide https://docs.microsoft.com/en-us/MicrosoftTeams/direct-routing-sbc-multiple-tenants but it's just for single SBC with teams multiple tenants. Thanks3.2KViews0likes5Comments
