11 Topicsinduce 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.747Views0likes0CommentsTeams 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).

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?Solved4.7KViews0likes6CommentsNeed 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,1.3KViews0likes2CommentsAdd second SBC to multi-tenant
Hi, I have question regarding adding second SBC to our multi-tenant setup. We have carrier tenant and one SBC. We have SBC on carrier base domain for example teams.domain.tld and every customer has it's own subdomain like customer1.teams.domain.tld. It has public IP address, certificate and everything works. Now we wanna add second SBC to configuration. Is it enough just to add second SBC into DNS with same name as first one but with different public IP? And also add DNS records for customers pointing to that same Public IP? Or do we need to add it with different name, different name for customers and add it to carrier tenant with New-CSOnlinePSTNGateway cmdlet? What is the correct procedure?Solved1.6KViews1like1CommentAnalogue devices and SBC
The way I understand it, if you want to keep your analogue devices, then aside from needing a certified Gateway that connects to an SBC. The SBC will need to be on prem? Otherwise if the SBC is in the cloud, the Analogue devices would need to go over the internet which presents a security risk? I guess the alternative is to have a private link to Azure/AWS and deploy a SBC there?Solved1.7KViews0likes2CommentsAvaya Session Border Controllers Certified for Microsoft Teams Direct Routing Non Media Bypass
After Cisco Cube/Voice Gateway/SBC was certified for Microsoft Teams Direct Routing its now another vendor which has been certified for Teams Direct Routing Services. Avaya SBC are now certified for Microsoft Teams Direct Routing enabling the organization who are using the Avaya SBC to interop with the PSTN Integration with Microsoft Teams. Currently SBC Avaya Session Border Controller for Enterprise (ASBCE) with the Release 8.1.1 version is Certified for Microsoft Teams Direct Routing. This will only support the Non-Media-Bypass Test Cases for Microsoft Teams Direct Routing.

Hi This is a bit old fashioned but we have 3 SBCS connected to Microsoft Phone System within our Teams Admin Centre / O365 tenant and we are trying to shape our outbound voice routing policies to simply try SBC#1 and SBC#2 in that order, rather than looking at the dialled number to decide which SBCS to use. It appears that MS Phone System outbound routing policies (what I would usually call trunks and trunk groups in PBX language) don't really allow for this. It feels like the only priority ordering exists for all policies together, when we want to put a user in a policy that simply tries 1 of 2 SBCs geographically local to them and nothing else. Am I just looking at this all wrong or is there a way to simply shape a Policy to try 1 SBC then another regardless of what number they dial? Currently we simply look for .* as the dialled number and pass it through to the SBC and then the SBC shapes the call accordingly. This works fine for us, but whatever we do, we cannot get it to try the second SBC if the first one is taken administratively offline.... ThanksSolved7.6KViews0likes7Comments
