ISDN replacement
ISDN technology is outdated and expensive. Replace it with a more modern, cheaper VoIP solution — the SIP trunk is its natural successor.
ISDN replacement — why switch now?
ISDN (Integrated Services Digital Network) was the basis of business telephony for decades, but the technology is now outdated and disproportionately expensive to maintain. Internet telephony (VoIP) beats it in every way: cheaper, more flexible and easier to expand.
Why is ISDN expensive?
- Physical copper lines and PRI circuits — standalone, expensive hardware
- Limited channel count, expandable only with hardware
- High monthly fees and maintenance costs
What you get by switching to VoIP
- SIP trunk — the natural, modern successor to ISDN
- Competitive per-minute rates (landline 4.5 HUF/min, mobile 20 HUF/min)
- Scalability: as many channels as you need
- Keep your numbers through portability
