MiVoice Office 250/Mitel 5000 / Re: Mitel 5000, Twilio, and SIP Integration

It looks like you will want to use a Twilio <Dial><Sip> to reach your Mitel over SIP.

The below links will help you there.

Use SIP With Twilio
https://www.twilio.com/docs/voice/api/sip-interface

TwiML Voice: <Sip>
https://www.twilio.com/docs/voice/twiml/sip

We just send a vanilla RFC 3261 SIP INVITE to your Mitel using SIP/UDP, SIP/TCP, or SIP/TLS.

You will want to use G.711U/PCMU as the Codec and RFC 2833 to handle DTMF.
