Salesforce CTI Deprecation: Migration Guide for IT and RevOps Leaders
Salesforce Open CTI is being phased out. This guide covers transition options, migration strategy, and how to avoid common pitfalls when moving to modern telephony integration.
Salesforce is deprecating Open CTI in favor of newer telephony integration methods. If your org uses Open CTI for click-to-dial, screen pops, call logging, or softphone interfaces, you'll need to migrate — and soon.
This isn't a "wait and see" situation. Open CTI will stop working, which means your sales and support teams will lose the telephony integration they rely on daily. The good news: you have options. The bad news: each path has tradeoffs around cost, flexibility, and implementation complexity.
This guide walks through the migration process step-by-step: how to choose the right replacement path, validate your integration works, pilot with a small team, and roll out without disrupting call workflows. We'll also cover the most common failure modes and how to avoid them.
The problem
This is a forced migration. Open CTI will stop working, which means your sales and support teams lose the telephony integration they rely on daily. Call logs, recordings, and disposition codes must survive the move. And you're doing this with limited engineering bandwidth, budget pressure, and zero tolerance for broken call flows.
Most 10–200 person orgs face the same constraints: IT teams handle multiple systems (not just telephony), new solutions must justify their cost, and you can't afford to add yet another vendor to an already sprawling tool stack.
Success looks like this: users click-to-dial, log calls, and route contacts without noticing the change. Call metadata (duration, disposition, recording links) still writes to Salesforce. And you gain improved reliability—fewer dropped calls, better call quality, faster screen pops—treating the migration as an upgrade opportunity rather than just a forced change.

Pick the right replacement path
You have three main options for replacing Open CTI. Each has clear tradeoffs around cost, flexibility, and implementation time.
Service Cloud Voice
Best for: Simple call workflows, trust Salesforce roadmap
Pros:
- Native integration
- Salesforce support
- Faster setup
Cons:
- Limited customization
- Salesforce pricing model
- Voice-only (no SMS/chat parity)
Third-Party CTI Adapter
Best for: Feature-rich needs (IVR, recording transcription, omnichannel)
Pros:
- Advanced features (IVR, analytics)
- Multi-channel support
- Battle-tested integrations
Cons:
- Vendor lock-in risk
- Per-seat pricing scales
- Integration maintenance burden
Custom Voice Agent Integration
Best for: Complex routing logic, agent-assisted workflows, full control
Pros:
- Complete flexibility
- AI-powered automation
- Exactly matches your workflow
Cons:
- Requires engineering capacity
- Longer implementation timeline
- Ongoing maintenance responsibility
Default recommendation for most orgs
- Start with Service Cloud Voice if workflows are: inbound/outbound calls, click-to-dial, basic call logging
- Choose third-party CTI if you need: advanced IVR, workforce management integration, multi-channel (voice + SMS + email)
- Build custom integration if: you're automating parts of the call workflow with AI agents, need non-standard routing, or current CTI setup is heavily customized
Instrumentation (log from day 1)
Capture these metrics during and after migration to validate success and catch issues early:
- Call connection rate — (successful calls / attempted calls) × 100. Detect telephony provider issues.
- CRM sync success rate — (calls logged in Salesforce / total calls) × 100. Ensure call metadata writes to Salesforce.
- Screen pop latency — Time from call start to contact record display. User experience indicator.
- Call quality (MOS score) — Voice clarity from telephony provider dashboard.
- User adoption rate — Active users / total licensed users, measured weekly.
Critical
Set up alerting for CRM sync failures before go-live. Silent failures = lost call data.
Step-by-step implementation
Migration breaks down into four phases: scope definition, data integration, pilot validation, and full rollout. Each phase has clear gates—don't proceed until criteria are met.
Define scope + success
Understand what you're migrating and what "done" looks like.
Inventory current CTI usage:
- List all CTI-enabled users
- Document call workflows
- Identify Salesforce integrations
- Catalog customizations
Gate:
Can you list every feature currently used? Do you know success criteria?
Data + integrations
Ensure call metadata flows correctly between telephony, Salesforce, and middleware.
Critical checks:
- Telephony provider API access
- Salesforce API limits check
- Data schema mapping
- Idempotency (prevent duplicate records)
Gate:
Test call creates Salesforce Task with all fields populated. Recording link works.
Pilot + validation
Validate the new system meets requirements before rolling out to all users.
Pilot strategy:
- Week 1-2: IT team only
- Week 3-4: One sales/support pod
- Week 5-6: Expand to 50% if targets hit
Gate:
Call connection ≥95%, CRM sync ≥98%, screen pop <2s, user issues <5%
Rollout + monitoring
Expand to all users, establish support process, plan for iteration.
Rollout approach:
- Phased by team (recommended)
- Dedicated Slack channel for support
- Daily office hours (first 2 weeks)
Monitor (first 30 days):
Daily: sync + connection rates. Weekly: adoption + quality + top issues. Bi-weekly: cost vs budget.
Risks & failure modes
These are the most common ways CTI migrations fail. Each has a mitigation strategy—implement them before go-live, not after issues appear.
Silent CRM sync failures
Calls complete successfully, but Task records don't write to Salesforce. Users don't notice until days later.
Mitigation:
- Real-time alerting on sync failures
- Daily reconciliation job
- Test with 3× peak volume
Feature gap discovery
Users expect feature X (e.g., call barge-in, whisper coaching) that worked in Open CTI but doesn't exist in new system.
Mitigation:
- Document every current feature
- Explicitly ask vendor about each
- Full workflow tests before commit
User adoption resistance
New system works fine, but users refuse to use it or work around it (manual dialing, external phone).
Mitigation:
- Involve users early in selection
- Hands-on training (not slides)
- Leadership reinforces expectations
