Why is Asterisk in the mix? If you call a SIP URI directly from Twilio, can't you land it directly on the ATA?

Voicemail, 7-digit dial (most SIP providers only take 10), forwarding, filtering, etc.

Twilio could theoretically handle these things for you, but they're typically handled in a PBX.

    Hm, maybe I should have been more specific. Given that this is an interesting hack to get a PSTN call to an analogue set through Twilio, why did they bother with the SIP proxy?

      I'm not sure I understand your question, but I think it's because the ATA (like most modern/cheap ATAs) only speaks SIP.
