WHY OUTSOURCE?
Why companies outsource their telephone service
The phone remains the channel customers trust most. For complex questions, complaints or urgent situations, customers pick up the phone. But telephone availability is also the most expensive and labour-intensive channel to organise in-house: you need enough cover, including during breaks, holidays and sick leave.
Byteleaders builds telephone teams that speak to your customers as if they were sitting in your own office. No recorded messages, no eight-layer menus, just real people who know your products and help right away.
Reachability
Missed calls are missed opportunities. We make sure your customers always reach a person, including outside office hours, at weekends and during peaks.
Personal and tailored
Our agents answer in your company name and follow your scripts and escalation protocols. The caller does not notice they are speaking to an external party.
Trained on your products
Together we build a playbook with all product information, frequently asked questions, escalation paths and exceptions. Our agents are trained on it thoroughly before they go live.
Cost saving
An in-house phone agent quickly costs EUR 40,000 or more per year, including employer costs. With us you only pay for productive time or resolved tickets, with no idle time.

Service in detail
What makes telephone service at Byteleaders different?
We are not a traditional answering service that only passes on messages. Our agents resolve questions directly. They have access to your Zendesk, CRM and relevant systems, so they can help customers within a single call, with no call-back needed.
Advanced VOIP/CTI integration
Our telephony exchange supports routing, transfers, IVR menus, queue management and call recording. You are reachable without having to think about it.
Detailed reports
What are people calling about? How long do calls last? What is the first call resolution? We measure everything and report monthly, so you can keep adjusting.
Flexible deployment
From full takeover to overflow only or out-of-hours cover. Our automated backbone checks the queue every minute and calls up an agent when it gets busy, so you have nothing to manage.
Multilingual
Our agents answer calls in Dutch, English, German, French and Spanish.
Curious what it would cost for your situation?
We would be happy to calculate it for you, without obligation and transparently.

FREQUENTLY ASKED QUESTIONS
Frequently asked questions about outsourcing telephone service
The questions we receive most often from companies considering outsourcing their customer service.
What does outsourcing telephone service cost?
You can choose from several pricing models: per resolved ticket (from EUR 2.18), per hour (EUR 26) or per conversation (on request). The best model depends on your call volume and the complexity of the conversations. We are happy to advise.
How does the call forwarding work technically?
We connect our VOIP/CTI exchange to your existing phone number through a simple forward. Your customers call your number as usual and are connected automatically to our agents. You do not need to change anything about your own telephony.
Can I outsource only outside office hours?
Yes, this is one of our most chosen models. Many clients answer the phone themselves during the day and forward to Byteleaders outside office hours, at weekends or during holidays.
Do I get insight into the calls?
Absolutely. Through monthly reports you receive insight into call volumes, call topics, average handling time and customer satisfaction. Calls are sampled for quality monitoring.
Do you use scripts or is it free conversation?
We work with a playbook we build together with you. No rigidly read scripts, but guidelines that keep our agents consistent and on-brand. The playbook is continuously refined.
How quickly can you start?
On average, onboarding takes 2 to 4 weeks, including technical setup, product training and quality assurance testing. Simple engagements can be faster.
