SMS messaging using Twilio with SIP

I'm trying to use Twilio to send and receive SMS on my iPhone. I've gotten inbound and outbound calling set up following these instructions. I'd like the equivalent instructions for SMS. I'm presently using Zoiper as a SIP client, but that's flexible.

The phone number configuration page (from here click a phone number) has a section called "Messaging" which allows one to configure a TwiML bin. However, I haven't been able to find any documentation about how to configure SMS over SIP, let alone TwiML code.

I don't believe you send SMS over SIP. SMS uses a protocol called SMPP. I couldn't see anywhere in the Zoiper documentation that mentioned SMS messages either. - philnash
Zoiper does have a "Chat" section. The two kinds of accounts it seems to support, though, are SIP and IAX. Presumably at least one of these supports messaging. - brandones
When I try to send messages via Zoiper (with a SIP account registered and successfully making/receiving calls via Twilio), I see a little red X icon, and the details say Error: Request Timeout (408). I can't find anything in Twilio's SMS TwiML docs about sending an SMS to SIP. - Jonathon Reinhart

Twilio doesn't support SMS or Video over SIP, only Voice. Sorry about that! let me know if you have any other question related to this.
