MS Teams orig/term carrier?

Fri Mar 26 21:42:32 UTC 2021

Despite having worked for an ILEC in network ops for 10yrs, I can't figure out how to answer this without an SS7 sniffer (which I obviously no longer have, nor access to an SSP or SCP).

What 3rd-party carrier(s), if any, does Microsoft use to originate & terminate MS Teams-to-PSTN voice calls in Canada?

Pointers to rabbit holes welcome, if you think there’s an actual answer at the end ;-).

Thanks,
-Adam
