How It Works
Three phases. One seamless experience.
Memory runs silently in the background. Callers feel it, but never see it.
<100ms
before agent speaks
Pre-Call Recall
When the call arrives, the caller's phone number is matched against the memory database instantly. Their profile is injected into the agent's context before a single word is spoken.
- Name, preferences, and history loaded
- Last call summary available
- Agent greets by name from word one
During
the conversation
Real-Time Extraction
As the call unfolds, the memory system listens alongside the agent. Discrete facts (preferences stated, details volunteered, decisions made) are extracted and tagged with type, confidence, and source.
- Preferences, email, address, and more
- Confidence-scored per fact
- Sensitive data flagged and protected
After
every call ends
Post-Call Consolidation
When the call ends, the profile is updated. New facts are added, corrections applied, and a natural-language call summary stored. Every subsequent call begins richer than the last.
- Profile updated automatically
- Call summary and outcome recorded
- Corrections supersede old facts
Everything that matters. Nothing that doesn't.
Caller Memory stores a structured profile for each returning caller, with two layers of knowledge that build naturally from every conversation.

Last call summary
Caller requested a follow-up appointment after treatment on 4 Jun. Prefers Thursday mornings. Confirmed 9am slot on 17 Jun. No outstanding issues.
Call history
Memory is not a summary. It is a ledger of individual facts.
A paragraph of notes cannot be queried, corrected or trusted. Every single thing an agent learns is stored as its own record, in a category, with a confidence score, the date it was first heard and the date it was last confirmed. The store is append only, so a fact is never quietly overwritten. You can always see what was known, and when.
Thirteen categories, sorted the way a person would look for them
Contact
Second number, best time to reach

Site address, access notes

Preferred name, who they work for
Preferences
Morning appointments, no voicemails

Shared memory
One customer, one memory, however many agents.
Most businesses do not run one agent. They run a receptionist, an out of hours line, a booking agent and a chaser, and a customer does not care which one they reached. Put those agents in a memory group and they all read and write the same caller profile.
Group the agents that serve the same customer
A caller who books with one agent is recognised by the next one, with everything the first learned already there.
Or keep them deliberately separate
Memory scopes are a choice. Two brands under one account, or a sales line and a support line, can stay entirely walled off from each other.
It stays current on its own
Every call in the group adds to the same profile, so the record does not depend on someone remembering to update it.
Memory group: front of house
One shared caller profile
Whoever picks up, the customer never repeats themselves.
Memory the agent can use is one thing. Memory you can search is another.
Every profile lives in a console you can actually work with. Search by name or number, filter by agent, sentiment, outcome or date, watch it update in real time as calls come in, and export the whole thing to a spreadsheet whenever you need it somewhere else.
Updates as calls land
The list is live. A call finishing now changes the row now, without a refresh.
Sentiment and outcome, tracked
Every profile carries how the last call went, so a customer heading the wrong way is visible before they leave.
Yours to take
Export to CSV or Excel whenever you want. It is your customer data, not something held hostage.
Compounding Value
The longer it runs,
the smarter it gets.
Memory compounds with every call. Businesses that deploy it today build an intelligence advantage no competitor can instantly replicate.
Month 1
Names and greetings
Your agent greets every returning caller by name. The frustration of re-introducing yourself is gone from day one.
- Name remembered
- Call history begins
- Returning callers recognised
Month 3
Preferences and patterns
Preferences, habits, and contact details accumulate. The agent anticipates. It doesn't just react.
- Preferences mapped
- Preferred times known
- Complaints tracked
- Email + address stored
Month 12
Deep caller intelligence
Rich, nuanced profiles built across dozens of interactions. A depth of context it would take a human receptionist years to accumulate.
- Full call history
- Behaviour patterns
- Long-term relationship context
- Competitive moat built
A caller who is remembered spends more with you.
Persistent memory means the agent picks up where the last conversation left off, instead of starting from nothing every time.
Use Cases
Memory works everywhere
people call.
Healthcare
Patients feel known. The agent recalls their last appointment, their GP preference, and that they asked about their flu vaccination. No-show rates fall.
· Appointment preferences
· GP preference
· Medical context notes
Real Estate
Buyers call back and the agent already knows their budget, bedroom requirement, and preferred school catchment. Conversion improves because continuity builds trust.
· Property criteria
· Properties viewed
· Budget and timeline
Hospitality
Returning guests receive a concierge-quality interaction. The agent knows their preferred room type, extra pillow requests, and dietary requirements.
· Room preferences
· Dietary requirements
· Past stays and extras
Automotive
The agent knows the vehicle, the last service date, and that the customer mentioned a noise from the front wheel. Bookings arrive pre-qualified.
· Vehicle details
· Service history
· Outstanding issues noted
Legal
Clients feel their matter is being managed attentively. The agent captures detailed context, not just a generic message, every time they call.
· Matter reference
· Communication preferences
· Awaited outcomes
Financial Services
Clients in complex financial processes feel informed and supported on every call, without disclosing data the agent is not configured to share.
· Case status context
· Product preferences
· Last human touchpoint
Remembering everything is easy. Knowing what not to show is the hard part.
A memory system that surfaces a card number to the wrong person is worse than no memory at all. Facts carry a sensitivity flag, and anything marked sensitive is masked by default everywhere it appears. Revealing one is a deliberate action on a screen that already checks who you are.
Sensitive facts are masked
Payment details and anything else flagged sensitive render masked by default, in one place in the code rather than per screen.
VIP, where it counts
Mark a caller VIP and every agent that shares the memory treats them accordingly from the first second of the call.
Do not call, honoured
A do-not-call flag on the profile travels with the caller, so no agent and no campaign rings them again.
Isolated per tenant
Profiles are read through row level security, so one account can never see another account customers. Not by policy, by database rule.
Caller memory is available on Growth and Command. If you operate somewhere with strict rules about storing personal data, that is a conversation worth having on the demo rather than after you have signed.
Built for compliance.
From the ground up.
GDPR & UK GDPR compliant
Built from the ground up for data privacy. Lawful basis templates, transparency best practices, and full documentation support included.
Configurable retention
Set the retention period per agent (30, 90, 365 days, or custom). Automatic deletion enforced at the platform level.
Sensitive data controls
Payment references, allergies, and complaints are flagged as sensitive. Sensitive fact types are disabled by default and require explicit enablement.
Right to erasure
Find any caller's profile by number, view all stored facts, and permanently delete on request. Every operation is audit-logged.
Data residency
Memory profiles are stored in your account's data region (EU, UK, or US). AES-256 encryption at rest, TLS 1.3 in transit.
Do Not Call propagation
DNC flag set during any call automatically suppresses the contact from all outbound campaigns. No manual cross-system sync required.
What people ask about caller memory
Mostly about how the recall actually works, and what happens to the data.
Sysevo matches an incoming call against a caller profile by phone number, so the agent has the person’s history before the first word is spoken. Memory is stored as individual facts rather than as a summary: each one has a category, a confidence score, the date it was first heard and the date it was last confirmed, in an append-only store so a fact is never quietly overwritten.
Everything included
Memory is one part of it. Here's the rest.
Everything below is in your account from day one, built in and switched on, with no separate service to buy or connect. This is what you get for your money.
Caller memory
Recognised from the second call on
A caller’s number is matched the moment they call, and their profile loads before the agent even says hello.
The details, remembered
Names, preferences, addresses and what happened on past calls, carried into the next one automatically.
Organised the moment it is captured
Contact details, preferences, orders and complaints are sorted into their own sections automatically, so a profile stays scannable instead of turning into a wall of text.
Tuned to your industryGrowth+
The fields memory looks for are pre-set for your industry, covering recruitment, property, retail and more, with anything else the agent picks up still captured as a custom fact.
One profile, the whole history
Every call is linked to the same caller profile, so nothing has to be repeated or looked up by hand.
Follows them off the phone, too
The same memory carries into WhatsApp and Telegram conversations, so a caller never has to reintroduce themselves on a different channel.
Shared across agentsGrowth+
Route a caller to a different agent and the memory follows them, so the story does not reset.
You set the rules
Choose what gets remembered, and clear a caller’s memory whenever you want.
Notes only your team can see
Flag a caller VIP or do-not-call, add tags, or leave a private note, kept separate from what the agent captures automatically, and every change is logged.
New information supersedes old, nothing gets erased
When something changes, such as an updated address or a new preference, the old value is superseded rather than overwritten, so the history stays intact until you ask for it to be cleared.
Read back as facts, never as instructions
What a caller says can update their profile, but it is never treated as a command. Nothing said on one call can change how the agent behaves on the next.
Card details never touch Sysevo
Payments run through your provider’s own checkout, so only the reference comes back into the caller’s profile.
Erasable on request
A caller’s profile and memory can be cleared whenever you need, and the change is logged.
Never shared between businesses
One customer’s caller profiles are isolated from every other Sysevo account at the database level, not just in the interface.
No add-ons, no second subscription, nothing to wire together yourself. It is one platform and one bill. Everything unmarked is on every plan; a handful of the heavier modules open up further up the tiers, and those are marked above. See what each plan includes.
This is the part of the platform this page is about. See everything else it comes with.
Your customer has told you thisthree times already.
They should not have to say it a fourth. Bring a number you have called before and we will show you the profile the agent builds, the facts behind it, and the greeting it produces.
