📞 Ensuring Great Call Quality

At Kiwi VoIP, delivering crystal-clear call quality is one of our top priorities. We use high-quality audio codecs and implement QoS (Quality of Service) tagging to prioritise your voice traffic across networks — ensuring your conversations sound as natural as possible.

🔗 On-Net Calls (Kiwi VoIP to Kiwi VoIP)

When you're making calls between Kiwi VoIP numbers, we control both ends of the call. That means:

• We automatically use HD audio codecs, like G.722, where supported

• This results in clearer, fuller-sounding audio — ideal for internal business calls

📢 Make sure your device supports G.722 or other HD codecs to get the best possible experience

🌐 Off-Net Calls (Calls to Other Networks)

For calls that go outside the Kiwi VoIP network (e.g. mobile, landline, or international), we use:

• G.711a/u – the standard industry codec for carrier interconnects

• QoS tagging – we mark voice traffic for priority handling wherever supported

While G.711 is not HD, it still provides very good voice quality and compatibility with nearly all phone networks worldwide.

🚀 Get the Best Quality – Use Kiwi VoIP Internet

Using Kiwi VoIP broadband ensures optimal call performance:

• We have full control of both voice and data traffic

• QoS tags are guaranteed to be recognised and prioritised

• You'll experience less jitter, fewer dropouts, and more consistent call quality

⚠️ If you use a third-party internet provider, we cannot guarantee QoS tags will be honoured — this may affect call stability or audio quality during peak traffic times.
