How to choose
Match channel priority first: most agents focus on WhatsApp plus voice, so confirm your main contact method. Check autonomy level—some book and follow up independently while others need quick human handoff rules. Review pricing and language support, especially for clinics or multi-language markets. Avoid agents that only train on documents if you need real-time voice or cart recovery. Test escalation paths before committing.
