Just begin to learn Twilio API. My intention is to make call directly from Android phone to any landline number. I have read QuickStart guide, build sample Android application and found that to make a call one need to have his own REST server.
I didn't have any experience with any SIP alike apps, but my understanding was that there's SIP provider server through which I could place a call and that's it... (with any kind of authorisation and so on).
So the question: is any possibility to place call using Twilio without my own server? Or as option - could someone advise me 3d party provider of those server which can be used to place call through Twilio?
