Do you get any response from Teams at all? A few base thoughts:
1. The first line of your example, it looks like the source port of the packet you’re sending is port 5060. Are you certain that this is sent as TLS? I’d normally expect to see an ephemeral TCP port. 2. You have outbound calls working, so I’m guessing that you have sbc.pride.md as a record when you run Get-CsOnlinePstnGateway, but it would be good if you confirmed this. 3. Also note that frequently issuing a change to teams returns a positive response, but takes a quite a long time to actually become enforced. For example, if you add a new gateway with New-CsOnlinePstnGateway, the commandlet may be successful, but it won’t actually work for anywhere from 5 minutes to three hours (yes, really, multiple hours…) We provide service to Teams, but use Ribbon gateways as the ‘last hop’ before Teams because they’re “officially” supported, and we’re offering this as a commercial service, so customers want to know that they’re using “officially supported” solutions. With that said, we do route the calls to the ribbon gateways through teams. Ben Kaufman [email protected]<mailto:[email protected]> From: sr-users <[email protected]> On Behalf Of Bugaian A.
