Call Daily’s dialOut API with

• DAILY’s API KEY for your domain as$TOKEN

• phone number you want to dial ($PHONE): e.g., +18622038924

• Twilio’s SIP URI: e.g., $domain.sip.twilio.com , e.g.: daily-twilio-integration

• Daily meeting room: $ROOM , can be

curl -H "Content-Type: application/json" \
     -H "Authorization: Bearer $TOKEN" \
     -XPOST -d '{"sipUri": "<sip:$PHONE@$domain.sip.twilio.com>", \
				"displayName":$PHONE, "video":false }' \

Twilio Configuration

A. Buy a phone number

B. Configure a SIP Domain (e.g., daily-twilio-integration — you can choose any name here. Whatever you choose, you’ll have to use in the examples)

C. webhook code that executes when the above SIP URI gets a dialout from Daily’s meeting room

This is code running at: https://ldcwrxkisf.execute-api.us-east-2.amazonaws.com/prod/twilioDialOutHandler — you will have to create your own lambda or similar to handle the hooks
