MS Direct Routing Integration

[bcmike]

Hi,

I'm looking for someone who has completed a successfull MS Teams integration directly with Freeswitch. I need some questions answered and some general consulting. I'm happy to pay for the time.

I have made it with Kamailio, and Teams works like a extension, MS-Teams 703 is 703 on FusionPBX

This will be the approach I try when I get around to doing it with FusionPBX.

 

[robvandenbulk]

... Are you working on Teams - Fusionpbx ...

I've got this working on an Audiocodes and can pass along one tip for the CallID_Prefix_Name to work on Teams it must contain a number.

ie. Support_RG (will not work)
Support_RG1 (will work)

I have Teams to FusionPBX now with Opensips, I did get it working in a limited way with direct Teams to FusionPBX. I'm sure I could with a bit of work go straight to FusionPBX but I see no value, better to keep it separate, I'll test the caller id prefix thing, thanks.

Maybe its a limit of the SBC, I just made this call to the ring group from 200?

Try calling in again to that RG from the PSTN. Let me know if that works.

 

[DigitalDaz]

I now get nothing at all from the PSTN!!!!!!!!!!!!!!!!!!!!!!

 

[DigitalDaz]

So this is using it as you said, I don't believe this is anything to do with teams being as when I dial the ring group from internal it displays correctly. Morover in the pic here, I added a prefix in the inbound too and that is now displaying though I think one should potentially override the other. Its late here now so I will dig into this tomorrow. I am on the very latest master on this too, I upgraded earlier.

 

[gflow]

I'm on 4.4.

When I dial external with a digit in the CallerID_Name_Prefix in my ring group I get nothing as well.

When I number a number (Support_RG1) it shows up nicely Support_RG1#88883333.

But as you said and I actually never tested that until now, it does seem to work fine when performing an internal number dial to the ring group so it must be a fusion issue. I'll look into this as well.

Kamailio MS-Teams-SBC

Does anyone know if we can handle presence in teams in one way or another?

I'm pretty sure you cannot get a Teams User's status over SIP. You must get it over an API. They support notification subscriptions too.

 

[DigitalDaz]

Thanks. Are you familiar with how we can inject events into Freeswitch?

 

[KonradSC]

Teams client -> teams server -> MS Graph Server -> Custom middleware that talks to MS & then injects events into Freeswitch -> FreeSWITCH -> BLF

What could possibly go wrong

I'm guessing that once you receive a status change from Teams you would need to call a lua script with parameters like fs_cli -x "luarun status.lua 1000 busy". That would then dump an event into FreeSWITCH. Kind of like MWI or Feature Sync.

Of course you'd want a little front end to manage which users that you want to monitor in Teams as well.

Sounds like a fun little project.
