Redirecting SIP calls from another SIP server to Teams user
I am trying to understand if SIP calls can be transferred/redirected from a another/thirdparty SIP server to a Microsoft Teams user. I was reading below links: https://docs.microsoft.com/en-us/microsoftteams/direct-routing-protocols-sip https://docs.microsoft.com/en-us/microsoftteams/sip-gateway-plan https://docs.microsoft.com/en-us/microsoftteams/direct-routing-plan As per my understanding we need to use Direct routing, and for direct routing Microsoft certified SBC need to be configured along with the SIP proxy. But if we have the URL for the Microsoft Teams SIP Endpoint and the credentials to access it, can we transfer calls from another SIP server by configuring the URL and credentials? Will it work or is this supported? I have below questions: 1. Can we transfer the SIP calls from another SIP server to Microsoft Teams user? 2. If it is possible what are the available ways of achieving this? 3. Do we need to have SBC configured for having this functionality, is it must? 4. Is there a document which explains this process step by step?
Is it possible to call a Teams contact from a SIP client, like Linphone?
There is a commercial solution, Cybergate (https://www.cybertwice.com/#:~:text=CyberGate%20is%20a%20subscription%2Dbased,any%20extra%20hardware%20or%20software), that allows to call a Teams contact from a SIP client. I was not able to find any other free or even commercial alternatives. I had a look at MS Graph API and chat bots, but this can programmatically trigger a call only between a bot (which is already a Teams account) and a user, so no luck there. Is there a way to call a Teams contacts from a SIP client? Can somebody point me into the right direction?
Microsoft Teams SIP gateway locations
Hi all, We have recently migrated to Teams and are now utilising our Skype 3PIP phones on the new Microsoft SIP gateway. When we sign in via aka.ms/devicelogin and enter in the code generated by the phones we get the following message: " You're signing in to teams sip gateway on another device located in Ireland. If this isn't you, close this page. " Sometimes it is Ireland and other times its Netherlands. I presume that this might be location of the SIP gateways (may be I am wrong about this!). This concerns our users as they think they are being directed to a non-approved site. If this is indeed the location of the gateways then does Microsoft publish an official list of their SIP sites so we have a better understanding and allay the fear of those logging in? Many thanks, RajenHow does Azure Load Balance SIP? Ref: Direct Routing setup with virtual SBC in Azure Cloud
With options under "health probe" to monitor TCP,HTTP and HTTPs ports can anyone help me understand how does the health probe monitors if the SIP services is accepting requests. Based on my reading, for HTTP, the health probe waits of 200 OK message. Will it be same for SIP ports (5060, 5061 or any other)? Example scenario, I have got 3 x virtual SBCs setup in an availability group with each SBC set for max 200 connections/sessions via CAC. I want that if all the 600 sessions on 1st SBC is occupied, the load balancer would sent new requests to 2nd SBC and so on. Now, if the Azure Load Balancer would just monitor if the SIP port is up, it won't find any issues since port 5060 (or any other as defined) would still be open on SBC01. I wanted to understand which kind of SIP message gets exchanged by the Azure Load balancer's health probe monitoring SIP interface/port.
