Routing Methods

Routing Method Description
Attendant When attendant routing is used, the first call in the queue will ring all of the agents at the same time. The first call agent to pick up the call gets the call. 
Serial* When serial routing is used, incoming calls will ring call agents one by one, starting from the beginning of the call agents list.
Round Robin When round robin routing is used, each call agent will get the same number of calls from the queue.
Longest Idle When longest idle routing is used, the next call in the queue will ring the opted-in call agent that has been in presence state "Available" the longest.

*Please review group management options for support of this routing method.

Opt-In

You may designate whether members of a call queue may opt-in or out of the call queue. This is similar to signing in an out of an ACD on a traditional phone system. This option may be found in each user’s Teams client under manage account settings/calls.
