Twilio is a Voice Over IP service that integrates with Agent Autopilot to allow phone calls, texts, and ringless voicemails.
Most field agents will spend $10-$20 a month on Twilio fees. They are super cheap. Around 1 penny a minute and 3/4 of a penny per text.
You will be copying the Twilio SID and Auth Token and pasting them in the Business Account Setup Form (make sure to show Auth Token before copying and pasting)
