Unable to call 200 help line using Microsoft Teams (US based)

[RaizelX]

Hello Team,

We would like to confirm if others are experiencing or is aware of this behavior. We are using Teams as our telephony service and we are able to call emergency numbers like 911 using Teams but not 211 helpline nor 800. Is there any documentation regarding this? Thank you!

Is 211 something local? I'm not familiar with it.
And 800? All by itself? That's odd
