Chatbots are usually the fastest win: website widget, WhatsApp, or help center — trained on your FAQs and docs. They reduce ticket volume and give 24/7 answers with CRM handoff.

Voice agents shine when customers still call: appointment booking, order status, lead qualification, and IVR replacement. They need telephony (e.g. Twilio), strong latency control, and escalation rules.

If your traffic is mostly web/app, start with a chatbot. If call volume is high or phone is your brand channel, prioritize a voice agent. Many teams launch chat first, then add voice on the same knowledge base — a pattern DevScribes implements for support platforms and AI voice products.
