Customer service
Distribute callback requests from phone, website and e-mail fairly across the team and handle them within the target time.
Available
uttek Call
Callback management – no callback gets lost again.
Callback requests from phone, website and e-mail become one call list: assigned automatically to available staff, with target times, redial rules, one-click outcomes and reports. Self-hosted, full source code, 5 to 100 users depending on tier.
Live demo without sign-up · your own demo copy with sample data (customer service, trades, sales) · admin view-only
A customer asks for a callback – and then? The note sits on the wrong desk, the e-mail gets buried, and by the time someone calls, the customer is unreachable. uttek Call turns this into a clean call list your team simply works through.
Every callback request gets a number, a deadline by priority (in your business hours) and an owner. In focus mode uttek Call always shows the next due call: click the number, talk, record the outcome with one key. Not reached? The next attempt is scheduled automatically.
Statuses, priorities, topics, teams, outcomes and redial rules can be configured in the admin area. Via uttek Connect, Call works together with uttek Tickets and uttek Customers: an unresolved concern becomes a ticket with one click, customers come from one shared customer file.
Database
SQLite out of the box, MySQL/MariaDB at the push of a button
Starts with SQLite – no database setup. As your business grows, switch to MySQL/MariaDB (PostgreSQL optional) with the admin wizard: test the connection, migrate all data, verify counts, switch over – with rollback.
The upgrade wizard is a uttek standard and is being built into every tool in upcoming versions.
uttek Connect
Works together – every uttek tool talks to the others
With uttek Connect you link your uttek tools by address and key: tickets become Dispo jobs, customer data comes from the CRM, feedback lands in the ticket and the customer history, shop orders in the CRM – at no extra cost and without a cloud middleman.

What uttek Call can do

Call back within X minutes per priority, calculated in business hours with public holidays. Per outcome (voicemail, busy, no answer …) its own delay until the next attempt, maximum number of attempts.
Learn more →Click-to-call
Call via tel:, sip: or callto: – with softphone, PBX or smartphone. Numbers are stored in one format, callers are recognised by their number.
Learn more →Callback form for your website
Customers choose a topic and preferred time slot; with spam protection, privacy notice and iframe embedding.

Learn more →Reports (Pro and up)

Frequently asked questions
Is this a subscription?
No. You pay once and use the purchased version indefinitely. 12 months of updates are included; renewing afterwards is optional.
Do I need a specific phone system?
No. Click to call uses the standard dial function (tel:, sip: or callto:) of your browser, softphone or smartphone. A direct PBX integration (CTI) is not included.
How many users can I create?
Basic includes up to 5 users, Pro up to 30 users and Enterprise up to 100 users – technicians and staff count as users. Exception: with the app add-on (one-time per company: €33 (Basic), €59 (Pro) or €99 (Enterprise)) you get as many app users as you need. There are no per-seat prices – if you need more users, simply choose the next tier.
What do I need to run it?
Web space with PHP 8.2 or newer. The database (SQLite) is built in; MySQL/MariaDB is optional.
Are text messages and e-mails sent?
E-mails yes, via your mail server. For text messages an SMS provider is connected. During the test phase e-mails and texts are only logged, not sent.
Can I try the demo?
Yes, without sign-up. Every visit gets its own demo database with sample data (customer service, trades, sales), deleted after 24 hours.
How secure are logins and data?
Passwords are only stored as a secure hash; new passwords need at least 12 characters and are checked offline against a list of leaked passwords. Everyone can set up two-factor sign-in via an authenticator app (e.g. Google Authenticator, Aegis) with backup codes, and the admin can require it per role. After 5 failed attempts a login lockout with increasing delay applies; “forgot password” sends a single-use link valid for 1 hour. Optionally contact notes and call attempt notes are stored encrypted with AES-256-GCM, with the key outside the web root. The “Security (status)” page shows all measures at a glance.
uttek Call in a bundle – cheaper and connected
Bundles save around 15–20% compared with buying separately – and the tools are linked via uttek Connect.
