Enterprise procurement framework for voice AI: single-vendor TCO, signed BAA, RBAC, SOC 2 evidence. Why CallSphere wins enterprise procurement vs Vapi.
CallSphere fires Twilio SMS in parallel with calls during after-hours escalations. Vapi has no SMS primitive. See the parallel notification flow and code paths.
SOC 2 audits demand consolidated evidence. CallSphere centralizes controls; Vapi customers must gather evidence from 5+ upstream vendors. Compare here.
