A Low-Risk Transition Path to Salesforce Voice

A phased approach to modernizing voice without disrupting operations

Replacing a contact center's voice infrastructure is high-stakes work. Disrupt the flow of calls and you risk frustrated customers, burned-out agents, and lost revenue.For organizations relying on legacy Open CTI setups, the move to Salesforce Voice and Agentforce Contact Center feels inevitable. Open CTI has a hard end-of-life date of February 28, 2028. The promise of native voice, unified routing, and AI-driven insights is compelling. But the fear of a disruptive cutover often stalls progress.It does not have to be a high-stakes gamble. By rejecting the big bang migration model in favor of a phased, parallel approach, you can modernize your voice channel while minimizing operational risk.

Why a big bang migration rarely works

Many contact centers operate with complex routing logic, strict compliance requirements, and tightly defined service levels. Attempting to replace all telephony and agent workflows overnight introduces unnecessary risk:

Disruption to critical queues. One misconfiguration can leave your most important customers stranded.
Data invisibility. Switching systems often leads to gaps in reporting, blinding leadership during the cutover.
Adoption failure. Agents forced to learn a new interface under pressure often struggle, driving up handle times.
No way back. Once the old system is unplugged, there is often no easy rollback if critical issues arise.

A low-risk transition sidesteps these dangers by keeping your existing CTI fully operational while native voice is introduced in controlled, reversible steps.

The principles of a low-risk transition

Before discussing implementation, the strategic principles that govern a safe transition:Parallel, not replacement-firstYour Open CTI system remains the primary engine while Salesforce Voice is proven in a safe environment. Both systems run simultaneously until the new one earns trust.Small pilots, not broad rolloutsStart with limited, lower-risk queues and specific agent groups to validate the model. Internal queues (IT helpdesk, HR support) are good candidates for the first wave.KPI parity before expansionThe new system does not scale until it performs as well as, or better than, the legacy system. Compare handle time, first-contact resolution, abandon rate, and agent satisfaction side by side.Reversible stepsEvery phase must have a clear rollback path. If a pilot queue has issues, agents go back to Open CTI while the team resolves them. Business continuity is non-negotiable.

Step 1: Define scope and end state

Successful transitions start with clarity.Inventory the current setupMap your current Open CTI usage. Document telephony providers, IVR routing logic, screen pop configurations, compliance tooling, and recording workflows. Audit the KPIs your operations team actually uses versus the ones they ignore. This establishes the baseline your new system must match.Define the destinationDo not just replicate existing workflows. Define what the target state should achieve that the current state cannot. Common goals include: real-time transcription, AI-assisted guidance for agents, unified routing across voice and digital, and native voice data in Salesforce for analytics and automation.Also decide whether your end state is Salesforce Voice with your current telephony provider (BYOT), Salesforce Voice with Amazon Connect, or full consolidation onto Agentforce Contact Center. The migration steps are similar. The destination shapes your long-term architecture decisions.

Step 2: Choose your telephony model

Validate that your telephony provider has a certified Salesforce Voice integration and a migration path from Open CTI. If you are starting with BYOT, confirm that your provider (Genesys, NICE, Cisco, etc.) supports the Partner Telephony framework.If you are evaluating Agentforce Contact Center as your destination, you can still start with BYOT as the initial migration step and consolidate telephony later. The key is removing the Open CTI dependency first.

Step 3: Prepare the environment

In Salesforce, ensure Agentforce Service licenses, Salesforce Voice entitlements, and Omni-Channel are in place and aligned with your user and skill model.In your telephony platform, stand up the configuration needed to support the Salesforce Voice integration. This includes routing profiles, queues, and contact flows that mirror or improve your current IVR paths.Train a small group of agents on the new console experience before any calls touch the system.

Step 4: Pilot with low-risk queues

Start small. Select one or two queues that are lower volume and lower risk. Good candidates:

Internal support queues (IT, HR, facilities)
Non-revenue queues with predictable patterns
Queues staffed by agents who have volunteered for the pilot

Run these queues on Salesforce Voice while everything else stays on Open CTI. Compare KPIs daily. Gather agent feedback. Fix issues in a contained environment before expanding.

Step 5: Expand based on results

Only after the pilot queues show KPI parity or improvement do you expand to the next wave. Each wave follows the same pattern: migrate the queue, run in parallel, validate KPIs, gather feedback, then commit.Revenue-critical queues (billing, retention, sales support) come last. By the time you reach them, your team has resolved the integration issues, refined the agent experience, and built confidence in the new system.

Step 6: Decommission Open CTI

Once all queues are running on Salesforce Voice and KPI parity is confirmed, you can retire Open CTI. This should be a non-event if the transition was phased correctly. Agents are already working in the new system. Reporting is already running on native voice data. The old system simply turns off.After decommissioning Open CTI, you can evaluate whether to consolidate telephony further. Organizations using BYOT may decide to move to Amazon Connect or Agentforce Contact Center based on the results and cost structure they have observed during the transition.

Timeline considerations

With the February 2028 deadline, a possible timeline looks like this:

Months 1 to 3: Inventory, scope, vendor validation, environment setup
Months 3 to 6: Pilot with 1 to 2 low-risk queues
Months 6 to 12: Expand to mid-priority queues based on pilot results
Months 12 to 18: Migrate revenue-critical queues
Months 18 to 22: Full decommission and optional telephony consolidation

This timeline leaves buffer before the deadline. Organizations that start in 2026 will have room to learn and adjust. Those that wait until 2027 will face compressed timelines and higher risk.
