How it works?
The Allo + Intercom integration does two things exceptionally well: it keeps your contacts in sync, and it makes sure no phone interaction ever falls through the cracks.
Users and companies
Allo pulls your Intercom users and companies directly into your Allo contacts. Every phone call you make will be matched against a real Intercom profile.
Interactions
Every call, text, or voicemail handled in Allo gets pushed as a note into the corresponding ongoing Intercom conversation.
User activity
Beyond live conversations, Allo also writes call events to each user's activity timeline in Intercom. Every phone touchpoint becomes part of the complete customer history.
AI Summaries
Allo's AI automatically generates a call summary and full transcript after every conversation. Both get pushed into Intercom alongside the interaction.
The phone gap in Intercom is now closed
Intercom is exceptional at managing digital conversations. But when your customers pick up the phone, that context disappears, until now.
Before and after Allo
See what changes when your phone system and Intercom actually talk to each other.
The Perfect Contact Sync
Stop building your contact list twice. Allo imports your Intercom users and companies so your team always knows who's calling with full Intercom context before they even pick up.
Your Intercom users are ready to call from day one
The moment you connect Allo with Intercom, your entire user and company database flows into Allo. Phone numbers, email addresses, company associations, all mapped and ready. New users added in Intercom appear in Allo automatically, so you never have a stale contact list.
When a call comes in from a known Intercom user, Allo surfaces their name, company, and recent Intercom activity instantly. Your team picks up knowing exactly who they're talking to and why they might be calling.
Every call lands in
the right Intercom thread
Your support team is handling a conversation in Intercom. Meanwhile, your colleague takes a phone call with the same customer. With Allo, both touchpoints end up in the same place automatically.
The notes include the call direction, duration, AI-generated summary, and a link to the full transcript. Your support team has complete context without switching apps.
If there's no active conversation, Allo creates one and tags it appropriately. Nothing slips through. Every phone interaction is accounted for in Intercom.
The full picture of every customer relationship
Beyond conversations, Allo writes events directly into each user's activity timeline in Intercom. Every call, every text, every voicemail becomes a permanent entry with timestamps, duration, direction, and AI summaries.
This is the single most valuable view your customer-facing teams can have. Instead of bouncing between a phone app, a CRM, and Intercom, everything is in one place. Who called, when, for how long, and what was discussed.

Frequently
asked questions
Are AI summaries always included in the Intercom note?
Yes. Allo's AI generates a clean summary after every call and includes it in the Intercom conversation note automatically. You can also include a link to the full transcript and the call recording. All of this is configurable in settings.
Is the contact sync bidirectional?
The contact sync pulls your Intercom users and companies into Allo, so your phone contact list is always up to date. Phone activity (calls, texts, voicemails) flows from Allo into Intercom. Changes made to contacts inside Allo are not written back to Intercom — Intercom remains your master CRM for user data.
Do I need a paid plan to use this integration?
Yes, the Intercom integration is available on the Allo Business plan. You can start with a free 7-day trial to test the full integration before committing.
Does Allo work on mobile?
Yes, that's actually Allo's core design philosophy. Allo is a mobile-first phone system, meaning it works seamlessly on iOS and Android, not as an afterthought but as the primary experience. Your team can make and receive calls on their mobile devices with a real business number, and everything syncs to Intercom just the same.
What happens if a caller isn't in Intercom?
If the caller's phone number doesn't match any Intercom user, the call is still logged and transcribed in Allo. You can choose to create a new Intercom user from Allo with a single click, or keep it as an unmatched contact. Nothing is lost.
What if the user has no active Intercom conversation?
If a matched Intercom user has no active conversation, Allo creates a new one and posts the call note there. The activity timeline is always updated regardless of whether there's an active conversation.
Who should use this integration?
Support teams, customer success teams, and sales teams that use Intercom as their main customer communication platform and also handle phone interactions. If you're tired of phone calls being invisible to the rest of your team in Intercom, this integration is exactly what you need.
