Here is one caveat that you may not realize:
PureCloud attempts to route callbacks, email replies, and message replies to the last agent who handled it. The agent must be on queue and not be fully utilized on those interactions. If the agent is not available, PureCloud routes the interaction to the next available agent. For more information about how to determine if an agent is fully utilized, see Configure agent utilization.If this happens, it can throw off the Service Level for Callbacks based on agent utilization and availability.
Also, this will affect (or not affect rather) the SL for voice:
Any interactions that leave a queue without an agent handling or transferring the interaction, including callbacks, count as flow-outs. Callbacks do not count as answered within service level, even if the callback was offered before the Service Level Target was reached.So, from what I read, you can't really have an SL for callbacks. Now, you can report on callbacks and calculate your own, but not sure you can have callbacks affect queue SL calculation.
