Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid literal translation 'голос поверх...'. Use the established term 'IP-телефония'.
- The 'P' stands for 'Protocol', not 'Program' or 'Port'.
- It's a system/technology, not just a single application like Skype.
Common Mistakes
- Pronouncing it as /vɔɪp/ (like 'voip') in formal UK contexts where /ˌviːəʊaɪˈpiː/ is preferred.
- Using it as a verb incorrectly ('I VoIPed him' is informal/tech jargon; standard is 'I called him via VoIP').
- Confusing it with general 'internet calling' which may use proprietary protocols not strictly IP-based.

FAQ
Frequently Asked Questions
Skype and Zoom are applications that *use* VoIP technology. VoIP is the underlying technical standard that enables voice calls over the internet, which these apps implement.
You can use VoIP with a software application on a computer or smartphone, a dedicated IP phone, or an analogue telephone adapter (ATA) that connects a regular phone to your internet router.
The primary advantages are significantly lower cost, especially for long-distance/international calls, advanced features (call forwarding, voicemail to email), and flexibility (use anywhere with internet).
Reliability depends on your internet connection and power. During a power outage or internet downtime, traditional landlines may still work, but VoIP services will not without backup power.
