Why cloud telephony
instead of a classic ISDN system?

ISDN is history. Cloud telephony offers more flexibility, lower costs and features a classic system could never provide – without expensive on-site maintenance.

Frequently Asked Questions

Straight answers to questions that matter to decision-makers.

How much does switching to cloud telephony cost?

expand_more
Costs depend on the number of employees and the desired feature set. In many cases companies save money from day one, as cloud telephony requires no expensive hardware, maintenance or ISDN lines. We will provide you with a transparent quote.

Can I keep my existing phone numbers?

expand_more
Yes, number porting is standard and available with all providers. Your existing landline numbers are seamlessly transferred to the new cloud phone system – without interruption.

Does cloud telephony work during an internet outage?

expand_more
Yes, with mobile fallback and failover solutions we ensure you remain reachable even during an internet outage. Calls are automatically redirected to mobile devices or alternative locations.

How long does the switch to cloud telephony take?

expand_more
The switchover typically takes 2–4 weeks. Setup runs in parallel with live operations so there is no downtime. The actual cutover usually happens over a weekend.

Which cloud phone systems does HELITS recommend for SMEs?

expand_more
For SMEs with up to 50 employees we recommend Cisco Placetel or NFON – both are designed specifically for German mid-sized businesses and are GDPR-compliant. Microsoft Teams Phone is ideal when Microsoft 365 is already in use. The choice depends on your existing infrastructure.

Can the phone system be connected to our CRM?

expand_more
Yes. Via CTI integration we connect your phone system to CRM systems such as Salesforce, HubSpot, Microsoft Dynamics or industry-specific solutions. Caller identification, automatic contact display and call logging are standard.

Does HELITS also offer support and maintenance for phone systems?

expand_more
Yes. Within a maintenance contract we proactively monitor your phone system, carry out updates and resolve faults with guaranteed response times. Standard SLA: response within 4 hours, Priority SLA: response within 1 hour during business hours.
