If agents spend half the shift listening to ringing lines, the dialer solution is the problem, not the people. Choosing the right contact center dialer Germany teams can run legally and comfortably comes down to two things: how the dialer places calls, and how well it fits German rules and working habits.
This guide walks through five dialing modes that KingAsterisk Technologies sets up for teams based in Germany. All five run on VICIdial and Asterisk, so you will see the real campaign settings behind each one. By the end you will know which mode suits your team, what a dialer costs, and how to start using it.
What German teams need from a dialer
Outbound calling in Germany is shaped by two rules. GDPR requires a lawful basis for processing phone numbers and call recordings. The UWG (Gesetz gegen den unlauteren Wettbewerb) requires prior express consent for advertising calls to consumers. For business contacts, telephone advertising may be permitted where there is at least presumed consent based on specific circumstances indicating a genuine interest in the call. This is general information, not legal advice, so confirm your process with your own counsel.
In practice, a contact center dialer Germany teams use should:
- store a consent date and source against every lead
- check your internal DNC list before each dial
- announce recording at the start of the call
- show a real German number as caller ID
- run the agent screen in German
The top 5 dialers for contact center teams in Germany
Here are the five modes, with the VICIdial settings behind each one.
1. Predictive dialer
A predictive dialer places several calls per free agent and adjusts the pace from live answer rates and talk time. In VICIdial this is Dial Method ADAPT_TAPERED, ADAPT_AVERAGE or ADAPT_HARD_LIMIT, with a ceiling set in Maximum Adapt Dial Level and a cap in Drop Percentage Limit.
For a large contact center dialer Germany campaign with 30 or more agents, this mode gives the most talk time per hour. The risk is abandoned calls, which German consumers report quickly. Keep the drop limit low and play a short message when a call is dropped.
2. Power dialer
A power dialer dials a fixed number of lines per agent, for example 1.5 or 2.0, and never changes it by itself. In VICIdial this is Dial Method RATIO with Auto Dial Level set to 1.5 or 2.0. It fits teams of 10 to 30 agents whose answer rates stay steady through the day. Watch the answer rate: if it jumps, two people can answer at once and one of them gets dropped.
3. Progressive dialer
A progressive dialer dials one line per available agent. In VICIdial this is Dial Method RATIO with Auto Dial Level 1.0. Agents get a short gap between calls and very few calls are dropped, which makes this the safest choice when consent must be exact. Talk time per hour is lower than in predictive mode, but the pace is easier on agents and on your drop rate.
4. Preview dialer
A preview dialer shows the lead record first. The agent reads the notes and clicks to dial. In VICIdial this is Dial Method MANUAL with Manual Dial Preview enabled. It suits insurance, finance and B2B teams where each call needs context. It is the slowest mode by volume and the strongest on call quality.
5. Auto dialer
An auto dialer works through a list and connects answered calls to an agent, or plays a recorded message. Teams use it for appointment reminders and payment notices to customers who have agreed to be contacted. Automated calls with promotional content need prior express consent under the UWG, so the rules above apply in full.
Which dialer is best for a contact center?
There is no single winner. Match the mode to your team:
- fewer than 10 agents and strict consent rules: preview or progressive
- 10 to 30 agents with steady answer rates: power
- 30 or more agents and large consented lists: predictive
- reminders and confirmations only: auto
Most teams end up running two modes, not one, inside a single contact center dialer Germany setup. For example, preview for key accounts and predictive for a large consented list, each in its own campaign.
Setting up numbers and the SIP trunk
People who search for a contact center dialer Germany number usually need two things: German numbers to show as caller ID, and a SIP trunk to place the calls. KingAsterisk does not supply numbers, DIDs or SIP routes. You get them from a carrier licensed in Germany, and we connect them to your dialer.
Use a number people can call back, such as a +49 30 (Berlin) or +49 89 (Munich) number. German rules do not allow hiding your number on sales calls.
Lead formatting matters too. German national numbers start with 0, so remove it and store 49 in the phone_code field. The Berlin number 030 1234567 becomes phone_code 49 and phone_number 301234567. In the VICIdial carrier settings, set Dial Prefix to 9 and use a dial plan entry like this:
exten => _949X.,1,AGI(agi://127.0.0.1:4577/call_log)
exten => _949X.,2,Dial(SIP/de-carrier/${EXTEN:1},,tTo)
exten => _949X.,3,HangupReplace de-carrier with your trunk name, and set the Campaign CallerID field to your German number. If you use answering machine detection (AMD), test it on real German greetings first. AMD is timing based, and settings tuned on English greetings can misread German ones.
How to use a dialer in a contact center
Here is the basic flow for a new contact center dialer Germany campaign.
- Load your list as a CSV with phone_code 49, the consent date and the consent source.
- Run the list against your internal DNC list before importing.
- Create a campaign and choose the Dial Method from the modes above.
- Add agents to a user group and set the agent screen to German.
- Write the script: greeting, company name, recording notice, consent check.
- Start with a test batch of 20 to 50 calls and listen to the recordings.
- Watch the real-time report and adjust the dial level or drop limit before scaling up.
How much does a dialer system for contact centers cost?
There are two ways to pay. A monthly subscription is charged per agent, and vendors commonly list somewhere between 20 and 70 euros per agent per month, depending on features. A licensed dialer is bought once and installed on your own server, with setup and support priced separately.
Run the numbers for your team. At 40 euros per agent per month, 25 agents cost 12,000 euros a year, every year. A licence is spread over all the years you use it, plus your server and support.
The KingAsterisk price depends on agent count, dialing modes, CRM link and the German interface, so a quote after a short call is more accurate than any list price. When you compare any contact center dialer Germany quote, ask about extra charges for recording storage, reports and API access.

KingAsterisk Technologies has 14 years of experience, with more than 900 contact centers set up and over 2,000 projects delivered. For Germany, we offer a custom VICIdial German interface, licensed installs on your own server and 24/7 technical support.
The KingAsterisk CRM dialer keeps the lead record, call history and disposition on one screen, so agents do not switch tabs between calls.
