Call queue show "call for unknown user" for first couple of calls for each queue
On new call queues or new auto-attendant, the first 2-3 calls will show
"call for unknown user" for a call coming into a call-queue
"transferred by unknown user" for a call coming in via the auto-attendant.
If I repeat the call a couple of times, it will finally start showing the display name of the related Resource Account.
Why is this not simply showing the information that should be in the SIP exchange for the call? Seems particular odd that it appears to have a slow fill cache process it seems to be performing. This also causes issues since you're obviously caching this information it doesn't reflect the current configuration if a resource account's display name is changed. Need to clear the cache manually (non-trivial process for users) or what an undetermined amount of time for it to refresh (not quick)
The issue Im seeing is I have multiple main numbers for each office, and we use a centralised Switchboard with a legacy PBX the switchboard displays the name assigned to the incoming number so that the switchboard operators can answer with the relevant office or business name.
I thought the purpose of the resource account having a display name was for it to display the name when routed through the Auto attendant to the Call queue and then display at the agent when being answered. Teams is not doing this right now
