Shared calling policy enabled user can not login to teams sip gateway enabled phones like VVX400/500
We have enabled shared calling policy with Rogers Operator connect and assigned to users, which works great but while logging in to sip gateway enabled device like Polycom vvx400s/500s it throws error that please assign a phone number to the user to login to this device. So, i run the Get-csonlineuser command for one of the user enabled with shared calling and line uri was empty even after assigning shared calling policy and incoming outgoing calls were working. Even on teams admin center user profile shows that there is an assigned phone number but because lineuri for that user is empty it did not allow a user to login to sip devices. Any work around or solutions to this? Because i opened a ticket with Microsoft engineering teams and product team but even they don't know the reason and solution. Any help is really appriciated. Thank you.
