The printer isn’t working
Small incidents come in every few minutes. Each call pulls a technician out of the work they are doing for another customer.
Industry · IT service providers
Every incident becomes a ticket. Not a sticky note.
When every technician is with a customer, Call0 answers the hotline: understand the incident, match the company, create the ticket, log the callback. With TANSS, directly in the ticket system—otherwise as a complete report to your team.
Start without an account.

Why Call0
Less phone chaos. More clear next steps.
The forgotten ticket
Promised on the phone, forgotten in the car: whatever is not in the ticket system shows up in no invoice and no handover.
Server down at seven
Before office hours the hotline is not staffed. The customer with a total outage waits just as long as the one who wants toner.
Capabilities
A conversation that fits your workflow.
You define the knowledge, required fields, responsibilities and boundaries. Call0 applies that structure during the conversation.
Take the incident
What is not working, since when, how many workstations are affected—in the customer’s words, as a usable description.
Match the company
With TANSS, Call0 looks up the company named in the system before the ticket is created, and asks again if there are several matches.
Create the ticket
Title, description, company, contact person and callback number—in TANSS, Zendesk, Freshdesk, Jira or ServiceNow.
Log a callback
If the customer wants a technician to call back, Call0 enters it in TANSS as a callback.
Give the ticket status
If the caller gives a TANSS ticket number, Call0 reads out the current status—without guessing.
No remote access, no passwords
Call0 does not access customer systems, does not reset passwords and does not give out credentials.

FAQ
Frequently asked questions.
Your exact setup depends on telephony, workflows and the integrations you want to use.
Which ticket systems does Call0 work with?
During the call, Call0 creates tickets in TANSS, Zendesk, Freshdesk, Zoho Desk, Help Scout, Jira and ServiceNow. For TANSS there are also callbacks, ticket status, comments and the company search. You connect other systems through a custom API.
Does Call0 resolve incidents itself?
No. Call0 takes the incident and creates the record. There is no remote access and no guidance on changes to customer systems that you have not explicitly approved as knowledge.
How are emergencies handled?
You define what counts as critical, a total outage for example. For those cases you store forwarding to the on-call technician or a flag that marks the ticket as urgent.
Do I have to change my phone number?
No. You can forward your existing number—permanently, only when the line is busy, or only outside opening hours. Alternatively, you get a Call0 number of your own.
Do callers notice that they are talking to an AI?
Yes, Call0 introduces itself as a digital assistant at the start of the call. The voice sounds natural and the conversation is short and clear—with no hold queue.
