Your AI Agent answered the call, handled the caller’s questions, and found a good reason to book. The last thing you want is to end with, “Someone will send you a link.”
Connect a calendar to your 800 AI Agent, and it can check availability and schedule the appointment while the caller is still on the phone. The right choice depends on how your business already manages time, leads, and customer follow-up.
Here are five calendar options to consider, starting with our top pick.
The best calendar integrations at a glance
| Calendar | Best for | Why it works with 800 AI Agents |
|---|---|---|
| Calendly | Most businesses | Uses your existing Calendly event types and availability rules |
| Google Calendar | Google Workspace users | Reads availability and books appointments to a selected calendar |
| Outlook Calendar | Microsoft 365 users | Keeps appointments in the Outlook calendar your team already uses |
| HubSpot Calendar | CRM-led sales teams | Keeps scheduling close to lead records and follow-up workflows |
| 800.com Calendar | Businesses that want fewer tools | Keeps basic appointment booking inside 800.com |
| Bottom line | Calendly is the best overall choice | Start with the calendar your team already trusts |
1. Calendly: Best Overall
Calendly is our top choice for most businesses because it gives you a dedicated scheduling system without forcing you to rebuild your workflow inside your phone platform.
When you connect Calendly to 800.com, your AI Agent books appointments through an active Calendly event type. Your existing availability and event settings continue to control what callers can book.
That makes Calendly a strong fit for businesses with more than one kind of appointment. A law firm might use separate event types for an initial consultation and an existing-client call. A home-service company might separate estimates from service appointments.
Calendly is a good choice if you:
- Already use Calendly on your website or in sales emails
- Need different event types for different calls
- Want one scheduling workflow across phone, web, and email
- Prefer to manage scheduling rules in a dedicated platform
To connect it, you need an active Calendly account and at least one active event type. Then select that event type in 800.com, update the configuration, and verify the connection.

2. Google Calendar: Best for Google Workspace users
If your team already lives in Gmail and Google Workspace, Google Calendar is the practical choice. Your appointments land in the calendar your team checks every day, so there is less chance of creating another schedule that someone forgets to monitor.
The 800.com integration lets your AI Agent read availability from a selected Google Calendar and book appointments to it. You can use your account business hours or set custom bookable hours. You can also define appointment length, start-time intervals, and buffers before or after meetings.
Those controls matter when a full calendar does not tell the full story. A contractor may need travel time between estimates. A consultant may want a 15-minute gap to finish notes before the next call.
Google Calendar is a good choice if you:
- Run your business on Google Workspace
- Want appointments added to an existing team calendar
- Need custom booking hours or meeting buffers
- Prefer a familiar calendar over a separate scheduling platform

3. Outlook Calendar: Best for Microsoft 365 users
Outlook Calendar is the natural fit for teams that manage email and meetings through Microsoft 365. Instead of copying bookings between systems, your AI Agent can place the appointment on the Outlook calendar your team already uses.
The 800.com integration reads availability from your selected Outlook Calendar and books appointments to it. You can set bookable hours, a time zone, appointment duration, start-time intervals, and buffers around each meeting.
This is especially useful for offices where scheduling needs to match established business hours. A legal office can keep consultations inside intake hours. A property team can leave enough space between appointments for travel.
Outlook Calendar is a good choice if you:
- Use Microsoft 365 across the business
- Want AI-booked appointments in Outlook
- Need control over booking hours and time zones
- Want buffers between meetings

4. HubSpot Calendar: Best for CRM-led sales teams
HubSpot Calendar makes the most sense when every booked meeting belongs to a lead, deal, or follow-up sequence. Keeping scheduling close to your CRM can help your sales team see the conversation that led to the meeting and act on it quickly.
800.com already connects with HubSpot to sync call activity and contact data. Call events can appear in HubSpot contacts and timelines, create new contact records, and trigger HubSpot workflows. A calendar connection would make this setup especially useful for teams that want the phone call, customer record, and next meeting in one sales process.
HubSpot Calendar is a good choice if you:
- Manage leads and deals in HubSpot
- Want call activity tied to contact records
- Use HubSpot workflows for sales follow-up
- Prefer meetings to stay inside your CRM process

5. 800.com Calendar: Best for keeping things simple
You may not need another calendar platform. If your main goal is to let an AI Agent book basic appointments, the 800.com Calendar keeps the workflow in one place.
This option is a good starting point for a small team that does not already depend on Calendly, Google Calendar, Outlook, or HubSpot for scheduling. It cuts down on setup and gives the AI Agent a clear place to put appointments.
The 800.com Calendar is a good choice if you:
- Want to start booking appointments with fewer tools
- Do not have an established calendar workflow
- Need a straightforward setup for one team or location
- Prefer to manage calls and appointments in 800.com
As your scheduling needs grow, you can move to a connected calendar that matches the tools your team uses every day.
Which calendar should you choose?
If you don’t already have a calendar in place, or you’re ready to upgrade your booking setup, choose Calendly. It’s our top recommendation because it gives you a dedicated scheduling workflow that can work across phone, web, and email.
If you’re happy with Google Calendar, Outlook Calendar, or HubSpot Calendar, keep using the system your team already knows. The best calendar is the one your team will keep current and check every day.
The calendar matters, but the real goal is faster follow-up. A caller who is ready to book should be able to confirm a time before the conversation ends.
Turn more calls into booked appointments
800 AI Agents can answer calls around the clock, collect caller information, qualify leads, and book appointments through supported calendars. Give callers a clear next step while their need is still fresh.
