How to Switch from Phonely to CallSphere: Migration Guide: production view
How to Switch from Phonely to CallSphere: Migration Guide is also a cost-per-conversation problem hiding in plain sight. This walkthrough section adds the steps a buyer (or builder) actually has to execute, not just the high-level pitch. Once you instrument tokens-in, tokens-out, tool calls, ASR seconds, and TTS seconds against booked-revenue per call, the right tradeoff between Realtime API and an async ASR + LLM + TTS pipeline becomes obvious — and it's almost never the same answer for healthcare as it is for salons.
Buyer walkthrough
Before signing a pilot, verify five things in this order. One, vertical depth — does the provider already have an agent template for your vertical (dental, salon, MSP, real estate, behavioral health), or are they pitching a generic chatbot they'll customize? Templates that already exist mean an integrations layer that already exists.
Two, integrations — your scheduler (Athena, NexHealth, Boulevard, Square Appointments), your CRM (HubSpot, Salesforce), your messaging (Twilio for SMS, AWS SES for email). If any of these are "on the roadmap," your pilot is actually a beta. Three, support model — do you get a Slack channel and a named CSM, or a help-desk ticket queue?

FAQ
How does this apply to a CallSphere pilot specifically? Setup runs 24 hours, the trial is 7 days with no credit card, and pricing tiers are $49, $99, and $149 — so a vertical-specific pilot is a same-week decision, not a quarterly project. For a topic like "How to Switch from Phonely to CallSphere: Migration Guide", that means you're not starting from scratch — you're configuring an agent template that's already been hardened across thousands of conversations.
What does the typical first-week implementation look like? Day one is integration mapping (scheduler, CRM, messaging) and prompt tuning against your top 20 real call transcripts. Day two through five is shadow-mode running, where the agent transcribes and recommends but a human still answers, so you can compare side-by-side. Go-live is the moment your eval pass-rate clears your internal bar.
Where does this break down at scale? The honest answer: it scales until your tool catalog gets stale. The agent is only as good as the integrations it can actually call, so the operational discipline is keeping schemas, webhooks, and fallback paths green. The platform handles the rest — observability, retries, multi-region routing — without your team owning the GPU layer.
