Do call queues in Microsoft Teams really need direct routing numbers? it has been suggested that any random number will work in the URI? for example.. I have a PSTN number assigned to an auto attendant. That attendant then is set up to send the calls to 3 groups, each group has a number configured via powershell - 88801, 02 and 03.... As teams should only be routing these calls to the groups from within its infrastructure should this work?
