Depends. If the customer is using Direct Routing, then it's whomever is providing their SIP trunk. If the customer is 
using Calling Plans, then it's Bandwidth.com.

Subject: MS Teams orig/term carrier?


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,
