📋 目次
1What internet speed do I need for a reliable Wi-Fi VoIP phone?
A minimum of 1.5 Mbps download speed is recommended for clear voice calls, but 5-10 Mbps is ideal for multiple simultaneous calls or video conferencing. Higher speeds ensure lower latency and fewer dropped calls, especially in busy networks.
2Should I choose a DECT or Wi-Fi VoIP phone for home use?
Wi-Fi VoIP phones are better for homes with strong, stable Wi-Fi coverage and multiple devices, while DECT phones offer better call quality in areas with weak Wi-Fi. Choose Wi-Fi if you want integration with smart home systems or mobile apps.
3How important is battery life for a Wi-Fi VoIP phone?
Look for at least 8-12 hours of talk time on a single charge for daily use. Phones with longer battery life are better for frequent travelers or those who use the device away from a power source for extended periods.
4What features should I prioritize for business use?
Prioritize features like HD voice, call waiting, voicemail, and integration with business apps like Microsoft Teams or Zoom. A phone with a built-in speakerphone and support for multiple lines or extensions is also essential for team communication.
5Are there security concerns with Wi-Fi VoIP phones?
Yes — ensure your phone uses end-to-end encryption and supports secure protocols like SIP over TLS. Avoid cheap models that lack firmware updates, as they may be vulnerable to hacking or eavesdropping over unsecured networks.
