How to Choose a Conversational AI Vendor for Telephony Infrastructure
Blog post from Retell AI
In selecting a conversational AI vendor for telephony infrastructure, businesses must carefully evaluate vendors' ability to integrate seamlessly with existing SIP trunk providers and manage telephony layers effectively to avoid integration failures. The guide emphasizes the importance of a structured evaluation framework, which includes scoring vendors on eight telephony-specific criteria like SIP trunk compatibility, response latency, call transfer reliability, and compliance certifications. It outlines the necessity of running SIP compatibility and latency tests under real production conditions, evaluating compliance and security infrastructure, and comparing pricing based on total cost of ownership rather than per-minute rates. Furthermore, it highlights the need for a production pilot to assess performance under live traffic, ensuring stable telephony infrastructure is prioritized over AI features. The guide also stresses the importance of retaining existing phone numbers and avoiding lock-in with platforms that require number porting. Key considerations include telephony stability, regulatory compliance, total cost, and the ability to handle concurrent call volumes effectively.
