induce delay on ringback tone
using direct routing with teams phone system ... noticed when a teams client dials out to external pstn number it pretty much straightaway sends calling party the ring back tone ... so there could be 2-3 ring back tones on the calling end (approx. 4-5 secs.) before the called party eventually receives the first ringing tone .. is there a way to induce a delay in that initial ring back tone Teams phone system sends to the Teams client ? i just don't want to start giving ringback tone straight away when 180 ringing from itsp is not received for another good 3-4 seconds. thanks.
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?

Transport connection all non-operational
Hi Guys, We're running an Anynode SBC with a carrier tenant and currently 2 customer tenants. The other day all of the transports for calls to Teams (sip[2,3].pstnhub.microsoft.com) all went non-operational for no apparent reason. I have a called logged with MS but have not received anything back from them as yet. I cannot figure out what has broken. There have been ZERO changes in our Teams environment and the SBC for the past month. Nothing has changed in the config at all. It just stopped working. I've checked everything I can think of and everything looks to be exactly as it was and configured correctly. Cert has not expired. I am baffled. Hoping someone has seen this behaviour and has some clue that can help. The only thing I haven't tried is a complete rebuild of the VM running Anynode. There are no DNS issues, I am at a total loss. This has been running perfectly since we implemented it a couple of years ago. If anyone has any clues, I'd love to here them. Outbound calls from Teams are working fine - it's just inbound not working (because the transports are all offline). Thanks, GlennTeams Toast Notification Showing "Unkown Users" When the Call Comes from Auto Attendant
We are running in problem where if I assign a direct number to the teams user and call that number the Caller ID of the caller is displayed in Teams Toast notification. But if we route the call via Auto Attendant and then to a call queue like: PSTN>SBC>Auto Attendant>Call Queue and put the same user in the queue, (who was called Earlier) then the Caller ID of the same caller is shown as "Unknown Users". We are using the setup with Direct Routing and Ribbon SBC 1000. Secondly, If we direct the same caller to a "Person in Organization" and direct all the incoming calls to the same user (Might be an operator) then again the called ID of the caller is "RECEVIED" properly. But whenenver the call enters a call queue, the caller ID turns into "Unknown Users". The incoming call format is already in E.164 Format. We have cleared the cache of the Teams Application, enabled/disabled the Caller ID policies. Even changing the caller ID policies does not have any affect on the incoming call. The version of the Teams App is "1.5.00.17656 (64-bit)". Any Suggestions?Need a guaidance for Direct Routing set up
Hi Everyone! I hope you are doing well. I am looking for step by step guidance to set up Direct Routing with different SBCs. Could you please share the links or documents if you have, and I would like to schedule a meeting to meet and learn. email address removed for privacy reasons Regards,
Teams Dev Setup Integration with SBC on Azure
Hi Everyone I am trying to test Teams Direct routing using Azure (trial) Cloud based SBC. Azure provide Public IP using which i am able to open the SBC. Problem is that i cant see to find Public IP of the Teams Dev platform which i can use on SBC to perform the integration. Is this something even available? Sorry i am quite new to Teams. Is this is something that's only available to partners?Avaya Session Border Controllers Certified for Microsoft Teams Direct Routing Non Media Bypass
