Why teams migrate voice agents

We see these reasons regularly.

Cost reduction

Vapi at $0.05/min adds up fast at 10K+ calls/month. Migrating to Edesy (₹6/min) or Bolna can cut bills 30–60% with comparable quality.

Indian language quality

US-built platforms (Vapi, Retell, Bland) underperform on Hindi + regional languages. Edesy and Bolna are tuned for Indian voice quality.

Compliance requirements

BFSI/healthcare need DPDP, RBI Fair Practices Code, HIPAA-aware setups. Some platforms ship these defaults; others require retrofit.

Indian telephony bundling

Edesy bundles Exotel/Twilio India. Saves the operational overhead of managing telephony separately from voice platform.

Data residency

DPDP Act 2023 and various sector regulations push Indian customers toward platforms that can host data in India.

Quality degradation

Platforms ship breaking changes. Sometimes call quality, latency, or function calling regresses. We migrate before it gets worse.

Need different capabilities

Maybe you started with a no-code platform (Synthflow) but now need developer flexibility (Vapi). Or vice versa.

Better analytics / observability

Some platforms have limited dashboards. Edesy + Bolna offer richer call-analytics out of the box.

Vendor consolidation

Using 4 platforms for 4 use cases is hard to manage. Many teams migrate to one platform (usually Edesy) for ops simplicity.

Common migrations we do

Most common direction is toward platforms with better India fit (Edesy, Bolna). Some are reverse for technical reasons:

  • Vapi → Edesy (cost + Indian languages)

  • Vapi → Bolna (Indian + open-source preference)

  • Retell → Edesy (cost; English quality comparable)

  • Bland → Bolna (Indian use cases)

  • Synthflow → Vapi (developer-first preference)

  • Voiceflow → Edesy (voice-only focus)

  • Twilio Studio → Vapi/Edesy (modernization)

  • Custom build → Managed platform (reduce maintenance)

  • Bolna → Edesy (managed vs self-hosted)

  • Edesy → Vapi (specific developer needs)

What we preserve in migration

Migration should be transparent to your customers — they should notice no change:

  • Phone number (caller ID stays the same)

  • Conversation feel (voice persona, tone, pacing)

  • Business logic (qualification rules, routing logic)

  • CRM integrations (HubSpot, Zoho, Salesforce events keep flowing)

  • Recording archive (exported and re-imported if needed)

  • Function calling specs (re-wired to new platform's tool API)

  • Compliance posture (TRAI, DPDP, HIPAA defaults maintained)

  • Performance KPIs (latency, conversion rate compared before vs after)

Migration pricing

Fixed pricing depending on source agent complexity. 40% deposit, 60% on delivery.

How the migration works

Predictable 5-step process with rollback option built in.

1

Day 1 — Audit current agent

We listen to 10–20 recent calls + review current platform's prompt, voice, function calls, integrations. Identify what to preserve vs improve.

2

Days 2-3 — Migration plan

Detailed migration plan: what changes, what stays, telephony cutover strategy, rollback plan if needed.

3

Days 4-10 — Rebuild on target platform

Agent rebuilt on target (e.g., Edesy/Bolna/Vapi). Prompts re-tuned for new platform's STT/TTS/LLM stack. Integrations re-wired.

4

Days 11-13 — Parallel run + comparison

Old and new agents run in parallel on 10% of traffic for 2-3 days. Compare quality, latency, conversion. Sign-off before full cutover.

5

Day 14 — Full cutover + old platform decommission

100% traffic to new agent. Old platform subscription cancelled. Account exported (for compliance) and deleted. Final demo + documentation.
