How can we make Microsoft Teams better?

Teams calling with on prem cisco CUCM

Around 45 million cisco iphone endpoints mostly via cisco on prem CUCM deployements.
Need Teams to integrate with on prem cisco CUCM so that we can use it as enterprise softphone with on prem PSTN cabability.
I am sure this would make teams adoption even more compelling within large enterprises like us.

    I am looking to achieve exactly what is mentioned below. Can someone guide me ??
    Tony:
    1) Inbound and outbound PSTN calls from Cisco Phones remain the same
    2) Inbound PSTN calls will not only ring the end user’s Cisco Phone but also ring the end user’s Microsoft Teams client through Cisco SNR feature
    3) Both Cisco and Microsoft users can call each other through internal short extension dialing. When that happens, both end user’s Cisco phone(s) and Microsoft teams client will ring at the same time.
    4) Microsoft Teams client can make PSTN calls through the existing PSTN/SIP trunks on premises. The outbound calls will show the end user’s DID as calling number

    We also need this integration.
    Microsoft has to adapt an easy integration strategy for Microsoft Teams with existing enterprise infrastructure.
    We use the CISCO phone system in our premises and for our call center and we need that to be integrated with Microsoft Team.

    Making a call using the Jabber plug in within MS Teams basically invokes Jabber to make the call. I can't find anywhere that I can use Teams to answer incoming calls.

    Anyone tried with Jabber plug in for Ms Team? How is it compare with the SIP trunk integration below?

    New to M365 and Teams. Coming from a CUCM environment. Is it possible to integrate teams voice with the CUCM without adding a "phone system" license to each user? We are looking at M365E3 licensing that does not include this.

    I've done this for Skype for Business. Should be the same for MS Teams as well.

    All you need to create a SIP trunk pointing to the Team server from CUCM and a SIP route pattern point to the same SIP trunk.

    Configure SNR for a specific user with URI ( usually email on MS Team end. eg : tom@yourcompany.com )

    SIP Route Pattern : *@yourcompany.com ----> SIP Trunk ( To Team server )

    Create a Trunk in Microsoft Teams server to receive calls from call manager

    Inbound from VG/CUBE will come to callmanager end point and since SNR is configured, both Cisco & MS end point will ring simultaneously

    If you have a Cisco CUCM Platform you can configure Jabber devices and get the Cisco Jabber Client activated on your MS Teams Tenant and link the Jabber instance and MS Teams client together and then you can use your on CUCM PSNT on prem Solution to make pstn calls.

    If you have 45 million endpoints in CUCM why wouldn't you use Webex Teams? It's a much cleaner app and works better. Integration is a couple clicks to make it work in control hub.

    @ Tervor Can you share the some more details how to set up SBC and what is the requirement to integrate call manager with Team.

    Hi All
    A couple of years ago I did an integration between Lync Server and CUCM. Now I need to do the same but with Teams. Who can share information about how to make settings on the Teams side?

    TIA
