I always get a little suspicious about how little Twilio talks about their SIP stack. Barely a mention of it except for 'Asterisk/FreeSwitch/JSR289'. All of those ostensibly can provide the same functionality (SIP, Sip Termination) yet no mention of why all three?

I mean, this is their core businesses/functionality.

EDIT: I didn't mean for this to imply I think something sinister is going on, or that I don't think Twilio is really cool! I'm just curious of why they went with what I would consider an unorthodox technology stack (the combination, not picking any one of the three).

I mean, wouldn't you guys think it was interesting if Github made a brief mention of the fact that some user information was stored in Oracle, others in MS SQL, and some in Postgres? shrug
