Mobility MS Teams App outbound call to PSTN?

Question

Mobility MS Teams App outbound call to PSTN?

Bai, Andy 241

Hi All,

We are going to integrate with Cisco UCM with MS Team, if we enable the phone system license, can we make an outbound call from the mobility Teams App? Can we make the call from the mobile phone MS teams application?

Thanks.

@Bai, Andy ,

The Phone System license is not enough. There are four steps to configure Direct Routing:

Step 1. Connect the SBC with Microsoft Phone System and validate the connection
Step 2. Enable users for Direct Routing, voice, and voicemail
Step 3. Configure voice routing
Step 4. Translate numbers to an alternate format

The step 4 guides you to use the Number Translation Rules policy to translate numbers for outbound calls, which is from a Teams client(caller) to a PSTN endpoint(callee).

For more details, please refer to the Example SBC configuration part in this link.

Hi Sharon,

Thanks for your information. Phone System License including the Direct Routing, right?
We have MS E3+Phone System License, and following the four steps will complete the voice calling to PSTN? Desktop Teams client can make an outbound call, how about the mobile Teams client?
About the Step 4 , we can also translate number in SBC instead of MS Teams, right?

Thanks.
