hi, 15 years ago i was using asterisk in combination with Cisco Cucm providing voicemail rather than paying for Unity. Fast forward to now and we are all-in with MS teams and i think its not just tinfoil hat thinking to be aware that we should have a plan for not having these cloud services available. I like the idea of having Asterisk back and connected to our audiocodes SBC’s and be able to service basic telephony services and contact center should it be needed.
Has anyone done this before ?
Yes.
You could also plug it into teams either directly with a small patch or over/via your audiocodes SBC.
Having a cloud provider hosting your numbers means being able to bypass the ingress point as well // —> Teams
// —> asterisk

the ITSP is only connecting to the Audiocodes SBC’s and Teams is using Direct routing. Unless there was a good reason to add asterisk to Teams to be able to collect and sync data it probably makes more sense to keep them seperate right?
Speaking as an IT Director that runs stuff like this for an org you are completely missing the point of redundancy here as well as cloud services.
All cloud services incorporate internal redundancy. At least, they all say they do. They tell you that part of why you pay them more money to provide the same service you could provide with on-prem hosting something yourself, is because they have redundancy.
Your choice is to either believe them and drink the kool aid or not believe them. And, if you choose to not believe them - as you are choosing to do here - with in my opinion, very good reason - then the simple fact is you are paying MORE money for WORSE service than you could do yourself - and therefore violating your primary fiduciary duty to your company to make profit.
We all work to make money to put food on our table. We do not work to put food on someone else’s table, that someone else being Microsoft’s Teams people’s table. When your job changes from making profit for your employer so that some of that is diverted into your own pocket, to making excuses and covering the behinds of the losers at some vendor, so that they can soak your employer and divert the money that should be going to you, into THEIR pockets, you have completely lost sight of the entire point of why you are working in the first place.
For you to even ask the question you are asking implies that you CAN setup an Asterisk system and self-host. Therefore, you don’t even need cloud telephony in the first place. If I was your CEO I’d be asking myself, why am I paying a salary to jon0881 when he’s turned his job into basically being a tech support gofer for Microsoft? I can fire him and hire some minimum-wage tech who knows nothing who can sit on the phone with Microsoft all day long, and the money I save doing that wil pay for the increased cost of paying Microsoft’s telephony fees.
I use Teams in my org. It is restricted to collaboration. Telephony is NOT a part of collaboration regardless of what the Cisco kool aid says. Telephony is a completely redundant system.
If I have a user who calls me and says “I have an important meeting that’s scotching because Microsoft cloud services just went down” I can tell them “pick up the receiver on your desk phone and dial your collaborators and use your mouth the old fashioned way. Live without the videocameras. Half your people have their cameras switched off in your videoconference meetings anyway so why do you even give a tinkers damn?” I can do this because I have not squashed telephony into videoconferencing so that if one card in the house of cards collapses the entire house collapses.
Instead of setting up Asterisk to back up telephony in Teams, you need to consider that telephony IS the backup for Teams, and decouple it from Teams so that if Teams goes down your Telephony isn’t pulled down with it. If you simply don’t remember anymore how to setup an on-premise server there’s tons of cloud providers who will host telephony separately from Microsoft Teams.
Anyway, I don’t mean to be harsh. At LEAST you are smart enough to begin to see through the baloney and lies of fads and IT assumptions and start questioning. Too many IT admins don’t even get to that place.
