Using Twilio's API, I would like to retrieve the data displayed on this page: https://www.twilio.com/voice/pricing/us but I cannot find the call that I need to make in order to retrieve the "SIP INTERFACE" pricing:
Are these values even available through Twilio's API? All I could find was Voice, Messaging, PhoneNumbers and Trunking.
The SIP-Interface has, as of now, a flat prices of $0.004 and doesn't have country-specific pricing like PSTN or ESIPT. Therefore, it's not included in the API.
