Taking the time down by hand
vs booking with Allo
Taking the time down by hand
Callers asked to leave a message and wait for a callback- A time promised on the phone, then double-booked
- Somebody typing the appointment in later, or not at all
- Evenings and weekends going straight to voicemail
With Allo
The meeting booked while the caller is still on the line- Only slots that are genuinely free, inside your hours
- The event on your Google Calendar, with nothing retyped
- Bookings taken after hours and at the weekend
Allo is an AI phone system,
not just an integration
The Google Calendar sync is one part. Allo is the phone your team calls, texts and gets coached from every day.

The one you choose. Allo only offers calendars you have write access to in Google, and if you don't pick one it books onto the account's primary calendar. You also set how long each booked meeting is, 30 minutes by default.
Yes. Any team member can connect their own Google account, and any connected account in the workspace can be the one an agent books from, including a teammate's. Changing which calendar it uses and how long the meetings are is restricted to the account's owner, an admin or a manager.
Booking rules. A 30 minute buffer between meetings and a 2 hour minimum notice are on by default, business hours are respected by default, and you can turn on a booking window to cap how far ahead callers can book, 60 days by default. Blocked dates are never booked over.
Allo only shows calendars you can write to. Check your sharing permissions for that calendar in Google, or connect the account that owns it.
Yes. The Google Calendar connection exists so your Allo AI receptionist can book a caller in during the call. It's what turns an after-hours call into an appointment instead of a voicemail.
