How Much Does It Cost?
VoixCall charges by where you're calling, not where you are. Calls to numbers in the Netherlands cost 55.8¢/min to landlines and 42.1¢/min to mobiles. At the landline rate, a 30-minute call to KLM, hold time included, comes to about $16.72.
Your first call is free. After that you pay from prepaid credit, with no subscription. Recording adds $0.003/min. Rates as of 2026-10-06; see current rates for the Netherlands.
Record the call and keep the reference number
A call to KLM usually ends with a case or reference number and a promise about what happens next. After a long hold, in a second language, it's easy to miss a digit.
Switch on Record on the VoixCall dialer before you call ($0.003/min). If you've also turned on "Record and transcribe my calls" in Settings in the web app, about a minute after you hang up Call History shows a short summary, the reference numbers that were said (each with a Copy button), what each side agreed to do next, and the full transcript, for $0.02/min.
Recording is off by default. KLM hears a short recording notice when the call connects, and only you can see your recordings and transcripts. Speech-to-text can mis-hear fast numbers, so check important digits against the recording. Recording laws differ by country. How call transcripts work →
