Many organizations are modernizing their customer service operations by moving from Open CTI to advanced cloud contact center solutions such as Salesforce Voice or Amazon Connect. These modern platforms offer AI-powered capabilities, real-time call transcription, intelligent routing, omnichannel support, and deeper integration with Salesforce Service Cloud.
However, migrating from Open CTI is not simply a matter of replacing one telephony solution with another.
Over the years, many Salesforce environments evolve with custom integrations, automation, workflows, APIs, reports, and user-specific configurations that depend on the existing CTI implementation. These dependencies often go unnoticed until the migration process begins, leading to unexpected delays, broken functionality, and increased project costs.
A successful Open CTI migration starts with a comprehensive assessment of your Salesforce environment. By identifying hidden dependencies early, organizations can reduce risk, maintain business continuity, and ensure a smooth transition to a modern contact center platform.
In this guide, we'll explore ten commonly overlooked dependencies that every organization should audit before migrating from Open CTI.
Unlike standalone telephony applications, Open CTI is often deeply integrated into Salesforce. Over time, organizations customize their CRM to support unique customer service processes, sales workflows, and business requirements.
These customizations may include:
Replacing the telephony platform without evaluating these dependencies can result in missing functionality, inconsistent customer experiences, and operational disruptions.
A structured audit helps organizations understand how voice capabilities interact with the rest of the Salesforce ecosystem before any migration begins.
Organizations that skip a dependency assessment often encounter challenges such as:
A proactive audit minimizes these risks while improving project planning and implementation accuracy.
One of the most overlooked aspects of an Open CTI migration is the level of customization built around the existing telephony solution.
Many organizations have customized their CTI implementation to support unique business processes, including:
These customizations may not automatically transfer to Salesforce Voice or another contact center platform.
Before migrating, document every customization and determine:
In many cases, organizations discover they can simplify processes instead of rebuilding legacy customizations.
Many Open CTI implementations rely on external telephony providers that connect Salesforce with PBX systems, SIP providers, or cloud contact center platforms.
Examples include integrations with:
These integrations may include custom APIs, middleware, authentication methods, or vendor-specific configurations.
During your audit, evaluate:
Understanding these integrations early helps avoid compatibility issues during migration.
Many Salesforce implementations include Apex code that interacts with CTI events.
Examples include:
Review all Apex classes and triggers to identify references to:
Custom code may require refactoring to support Salesforce Voice or another telephony platform.
Ignoring custom Apex dependencies can result in broken automation after migration.
Although many organizations have migrated to Lightning Experience, legacy Visualforce pages are still common in Open CTI implementations.
You may find custom components used for:
Similarly, Lightning Web Components (LWCs) or Aura Components may interact with Open CTI APIs.
During the assessment, identify:
Modern platforms such as Salesforce Voice may offer native alternatives that eliminate the need for some legacy components.
Call history is essential for customer service reporting, compliance, and sales visibility.
Organizations often customize call logging to capture:
Before migration, determine:
Preserving historical call information ensures reporting continuity and supports future customer interactions.
The first five dependencies represent the technical foundation of most Open CTI implementations. Customizations, integrations, custom code, user interfaces, and historical call data are often deeply connected to business operations.
Identifying and documenting these dependencies before migration helps organizations:
A thorough technical assessment at this stage lays the groundwork for a successful migration and minimizes unexpected issues later in the project.
Many organizations have built business processes around Open CTI using Salesforce automation tools. These workflows often trigger actions based on call events, case updates, or customer interactions.
Examples include:
Before migrating, review all:
Determine whether these automations depend on Open CTI objects, fields, or events. Updating them before migration helps prevent broken workflows and ensures a seamless transition.
Salesforce reports and dashboards provide valuable insights into contact center performance. However, many organizations build these reports using data generated by Open CTI.
Common reporting metrics include:
If the underlying data structure changes after migration, existing reports may no longer function correctly.
During your audit:
This ensures business leaders continue to receive accurate operational insights after migration.
Security settings are often overlooked during telephony migrations.
Users may have permissions specifically configured for:
Review:
A security audit helps ensure agents, supervisors, and administrators have appropriate access once the new telephony platform is deployed.
Most enterprise Salesforce environments connect with multiple external applications.
Examples include:
Many of these integrations exchange call-related information through APIs or middleware solutions such as MuleSoft.
Before migration:
Ignoring API dependencies can interrupt critical business processes and impact customer service operations.
Technology is only one part of a successful migration. Even the most advanced contact center solution will struggle if users are not prepared for the transition.
Moving from Open CTI to Salesforce Voice introduces new features such as:
Without proper training, organizations may experience:
A structured change management plan should include:
Preparing users early increases confidence and accelerates adoption of the new platform.
A successful migration requires more than replacing telephony software. Following best practices helps reduce risk and ensures business continuity.
Review your Salesforce environment, integrations, customizations, automation, reports, and user requirements before planning the migration.
Engage customer service managers, Salesforce administrators, IT teams, and business users to understand current processes and future requirements.
Not every customization needs to be rebuilt. Remove outdated workflows and simplify processes where possible to reduce complexity.
Validate integrations, automation, reporting, security, and user workflows in a sandbox environment before deploying changes to production.
For large organizations, consider a phased implementation. Migrating teams gradually reduces operational risk and allows time to address issues before a full rollout.
Track key performance indicators such as call handling time, first-call resolution, user adoption, and customer satisfaction to measure the success of the migration.
