How a call actually goes
Brookline Print and Design
- Assistant
Thanks for calling Brookline Print and Design. I'm an AI assistant for the team, and this call is recorded. How can I help?
- Caller
Hi. What are your hours, and do you make custom signs for events?
- Assistant
We're open 9 to 5, Monday through Friday, and yes, the team makes custom signs and banners. What's the event?
- Caller
A grand opening next month. I'd like to talk to someone about options.
- Assistant
Jordan on our design team is the right person for that. Would you like me to connect you now?
- Caller
Yes, please.
- Assistant
Jordan is with another customer right now. Can I take a message and set up a callback?
- Caller
Sure. It's Sam, (800) 555-0142. Tomorrow morning works.
- Assistant
Got it, Sam. Jordan will call you tomorrow at 10 AM. Anything else I can help with?

When a caller needs a person
When a caller needs more than an answer, the assistant gets them to the right person, or makes sure that person calls back.
- An inbound call comes in.
- The assistant answers general questions and works out who can help. If the caller is urgent or ready to buy, it offers to connect them.
- Nobody is transferred without the caller saying yes.
- If the teammate answers, the call goes straight to them.
- If nobody answers, the assistant takes a detailed message, emails that person and puts a callback hold on their calendar.
