Open CTI Is Reaching End-of-Life. What Comes Next?
For over a decade, Open CTI has been the backbone of Salesforce telephony integrations. It allowed organizations to connect third-party telephony systems directly to the Salesforce console, with features such as click-to-dial, screen pops, and call logging.
But the Salesforce roadmap has shifted.
Open CTI is now entering retirement and will no longer receive enhancements, signaling Salesforce’s move toward Service Cloud Voice as the future of voice interactions within the platform.
For organizations running contact centers on Salesforce, the question is no longer if migration will happen — it’s how to migrate without disrupting customer service operations.
Why Salesforce Is Moving Beyond Open CTI
-
Open CTI was designed when voice was simply an extension of the agent desktop. Modern contact centers operate differently.
Customers expect support across:
- Voice
- Messaging
- Chat
- Social channels
At the same time, organizations want to leverage AI for:
- Real-time transcription
- Conversation insights
- Next-best action recommendations
- Intelligent routing
Service Cloud Voice was designed to support this new environment by embedding voice natively into Salesforce’s service platform, rather than treating telephony as an external integration layer.

What Migration Really Means for Contact Centers
Migrating from Open CTI to Service Cloud Voice is not just a technology upgrade.
It involves rethinking several parts of the service architecture:
- Telephony infrastructure
- Contact center workflows
- Data integration
- Agent experience
- AI enablement
Organizations that treat this as a simple replacement project often run into problems. The more effective approach is to treat migration as a phased modernization of the voice stack.
A Practical Migration Approach
1. Assess Your Current CTI Landscape
Start by understanding how Open CTI is currently used.
Typical dependencies include:
- Custom screen pops
- Click-to-dial workflows
- Call logging logic
- Telephony routing rules
- Third-party integrations
This helps determine what needs to be replicated, redesigned, or retired.
- Define the Target Voice Architecture
Service Cloud Voice supports multiple telephony models, including:
- Native Salesforce telephony
- Partner telephony providers
- Bring-your-own-telephony integrations
The right architecture depends on:
- Existing telecom providers
- Compliance requirements
- Call routing complexity
- Regional infrastructure
- Redesign the Agent Experience
Service Cloud Voice enables a more contextual service experience.
Agents can access:
- Real-time call transcription
- AI recommendations
- Unified customer history
- Integrated omnichannel routing
Instead of replicating the Open CTI interface, focus on optimizing workflows around these capabilities.
- Introduce AI Gradually
One of the biggest advantages of Service Cloud Voice is AI integration.
Capabilities can include:
- Call transcription
- Conversation analytics
- Automated summaries
- Next-best action guidance
However, introducing these features gradually helps ensure adoption.
- Execute Migration in Phases
A phased migration approach reduces operational risk.
Typical rollout stages include:
Phase 1: parallel environment setup
Phase 2: pilot team migration
Phase 3: workflow optimization
Phase 4: full contact center rollout
This allows organizations to transition smoothly without interrupting service operations.
Common Challenges During Migration
Organizations moving from Open CTI often face a few predictable challenges:
Telephony vendor compatibility
Not all vendors support Service Cloud Voice integrations.
Legacy workflow dependencies
Custom scripts and call handling logic may require redesign.
Agent training and adoption
The new interface and AI capabilities require onboarding.
Data governance
Voice data and transcription introduce new compliance considerations.
Addressing these early ensures the migration delivers value rather than disruption.
Our POV: Migration Is an Opportunity to Modernize Service
At ABSYZ, we see Open CTI migration as more than a technical upgrade. It’s an opportunity to modernize customer service operations by:
- Unifying voice and digital channels
- Enabling AI-driven service interactions
- Improving agent productivity
- Building a scalable service architecture
Organizations that approach migration strategically don’t just replace Open CTI — they build the foundation for the next generation of contact centers.
The Bottom Line
Open CTI served its purpose well, enabling Salesforce contact centers to integrate voice for more than a decade.
But as customer expectations evolve and AI becomes central to service delivery, the limitations of legacy CTI integrations are becoming clear.
Migrating to Service Cloud Voice allows organizations to move toward a more unified, intelligent service platform — one designed for the future of customer engagement.
