SIP support is a win for Plivo. I love Twilio and the overall constant innovation in the space, but inventing proprietary mechanisms (Twilio Client) is backwards for telephony.

Plivo is on the right track -- http://plivo.com/opensource. I'm excited to use this and watch them grow.

Even our hosted cloud supports SIP and we dont lock you in with our carriers. :)
