What is the difference between Twilio Elastic SIP Trunking, and Twilio SIP -


basic question here...for making calls in/out of twilio, between pstn numbers , sip endpoints (e.g. pbx), seems accomplish using 1 of 2 methods:

  1. twilio sip (using twiml translating between pstn call , sip call)
  2. elastic sip trunking

i'm wondering main differences in these methods are. seems twilio sip have use of twiml-based applications, , sip trunking not...is difference?

elastic sip trunking twilio voip carrier option global reach such load balancing / geographical redundancy , every other interconnect pain point handled twilio , can focus on application , not worry interconnect partners , call termination in different countries.

i believe, after having built partnerships call terminations applications making calls using twiml, decided open infrastructure applications dont have written on twiml.
