Subject: Question about PSTN forwarding charge on invoice [INVOICE NUMBER]

Hello FlyNumber support,

I am the administrator of our FlyNumber account and I have a question about a recent invoice.

Invoice number: #944073
Period: from 1. september to 1. october
Charge: “PSTN forwarding” - 19.69 USD

We do not have any PSTN forwarding configured. The PSTN Forwarding tab in our phone system panel is empty. We use one Slovak number (+421 55 230 2623) with an IVR menu, and incoming calls ring users only in the phone system app on their mobiles. Our users do have “Enable external outbound calls” turned on in their app configuration, so they can call regular phone numbers.

Could you please tell me:

  1. What exactly was charged as “PSTN forwarding” on this invoice (which calls, dates, destination numbers, and minutes)?
  2. Are outgoing calls from the app to regular phone numbers billed under this name, or is the charge from inbound calls forwarded somewhere else, for example in a call flow module?
  3. Where in the panel can I see the cost of each call? In our Outbound CDRs and Call Logs views there is no cost column.
  4. How can I find out which module or setting is generating these charges?

Thank you for your help.

Best regards,
František

Hi @juraj,

That line is your team’s outgoing calls from the app to regular phone numbers. On invoices from our older billing system, per-minute calling is labelled “PSTN forwarding” whether someone dialed out or a call flow forwarded a call, so nothing is being forwarded on your side and there’s no module to look for.

Those calls are billed per minute from your prepaid balance and invoiced every two weeks. The price depends on where each call goes, and the rates page lists it by country. The phone system panel doesn’t show a cost per call, so we’ll email you the call-by-call breakdown for that invoice.
