I'm using the Telephony Forward Call API to forward a call to an extension (in this case, a call queue). We want to pre-populate the call queue with members before the call is forwarded.
I get successful Status Code responses to make all the API calls... however, the newly added queue members are not invited on calls until they receive an email notification stating they're added. Likewise, the members that are removed, will get rang to until after some time passes.
I don't know the exact timeframe, but it takes about a minute before the desired behavior is achieved after make the Bulk Assign API call.
