Add Outbound Rule to Teams
1. Outbound Rules
2. Select + Add
3. Configure Rule
Below is an example rule on how to point calls to Teams with a prefix:
Rule Name: VTS Slave Bridge
Calls to Numbers starting with prefix: 8080
Calls to Number with a length of: 8
Route: VTS Teams | Strip Digits: 4
In our example, we could dial 80802048, then the call would go to Teams as 2048, as the 8080 would be stripped off. Our extensions are 4 digits in length. If we are doing a 3 digit extension, the length would be set to 7.
4. Finish the Outbound Rule by pressing "OK"
Add Extension and Routes to a User in Teams
1. Log into your Teams account via PowerShell
See guide here
2. Add Voxtelesys SBC/PSTN
If you haven't already set up your Voxtelesys SBC please refer to these instructions.
- Skip the "Assign DID and Voice Routing to Users" part as you will do that a little differently below.
3. Add Extension Number to User
Command:
Set-CsUser -Identity “user@example.com” -EnterpriseVoiceEnabled $true -HostedVoiceMail $true -OnPremLineURI Tel:2048
- For
user@example.com, set the user's email that you want to assign the caller ID. - For
2048, set the user's extension number on the 3CX.
4. Grant User Access to Voice Routing Policy
Command:
Grant-CsOnlineVoiceRoutingPolicy -Identity “user@example.com” -PolicyName “voxtelesys”
5. Test calls in and out of Teams/3CX
Dial the extension/user on Teams with the prefix:
3CX strips the prefix off and dials the slave bridge.
Teams can be answered on your desktop or cell phone app.
Now test call back into 3CX by dialing the extension number (no prefix needed).
For calls to ring to the Teams client all the time, you can assign the prefix and extension as the mobile number, then select ring my mobile simultaneously on the forwarding rules.
