All three support Twilio. Retell has the deepest telephony integration. Bland has built-in dialer for outbound. Vapi gives you the most flexibility.
Vapi supports multiple model providers including Claude. Retell primarily uses OpenAI. Bland uses their own + OpenAI.
All three operate primarily in US regions. For strict Canadian data residency, custom builds on AWS Bedrock Canada Central are the safer choice.
