From a Java application, what is the best way to be able to dial a phone number (via any API or service) and receive an SDP from this endpoint?
I don't want to be able to just call a number (by using Twilio or Plivo or similar), I want to place a call but I want to have control over it, such as the other endpoint it connects to, by taking advantage of a Session Description Protocol packet.
Should I look in the SIP direction? Something like Sip trunking? I think this is the direction but it looks like there isn't a popular java SIP library to use (I've been looking at peers but I don't know if it very good)
