Keep Your PBX: How the Connector Works

For many existing 3CX users, keeping the PBX intact while adding a connector to the CRM is the preferred integration approach. This method preserves the native 3CX SIP infrastructure and call control APIs, ensuring no disruption to telephony services.

  • 3CX Side Wiring: Utilizes the Call Control API and webhooks to capture call events without altering SIP configurations.
  • CRM Side: Field mapping and workflow triggers enable automatic logging and customer data updates.
  • Connector Side: Handles event ingestion, contact matching, and attaches call recordings to CRM records.
  • Monthly Cost: See the pricing page for current options.
  • Training: Recommended 1-2 days for administrators and 2-4 hours for sales teams to maximize adoption.
  • Migration Timeline: Configuration usually takes 1-2 weeks with no need for PBX migration.

This approach allows businesses to maintain their existing telephony investment while gaining CRM integration benefits.

What 3CX CRM integration looks like in practice — a typical first 90 days

Days 1 to 14: discovery and connection

During the first two weeks, the operations lead focuses on auditing the existing 3CX dial plan to understand the current call routing and queue setup. This involves listing all call queues and extensions that require CRM context, ensuring that each queue is paired with the relevant stage in the CRM pipeline. The lead then initiates the OAuth handshake between the 3CX call control API and the connected CRM platform to establish secure communication. Throughout this period, the existing 3CX deployment remains unchanged, with no need for rip-and-replace or number porting, preserving the current telephony environment while preparing for integration.

Days 15 to 45: workflow design and pilot

In this phase, the team selects three to five high-value workflows to implement, such as missed call SMS notifications, post-call disposition logging, and voicemail-to-task conversion. These workflows are configured within the connected CRM workflow builder to automate routine tasks. A pilot group of agents is chosen to test the integration, allowing the team to observe how call data flows into the CRM record-of-truth. Weekly reviews are conducted to monitor call-disposition completion rates and identify any issues or areas for improvement. This pilot helps validate the integration setup and informs adjustments before full rollout.

Days 46 to 90: rollout and optimisation

After successful piloting, the integration is rolled out to the full team. Training sessions are held for sales and support managers to ensure they understand the new workflows and system capabilities. Baseline metrics such as first-call resolution, missed-call recovery rate, and average handle time are captured to measure performance. The team then conducts the first optimisation round, refining workflows and addressing any challenges identified during the pilot. Throughout this period, the integration operates alongside the existing 3CX licence, so there is no need for a parallel contract review by finance, maintaining cost stability.

How 3CX CRM integration changes daily workflow for sales and support teams

Sales team: from cold list to closed loop

A typical day for a sales representative begins by opening their CRM call queue, where they see a list of prospects to contact. Using the 3CX softphone integrated within the CRM, the rep clicks to dial a contact directly, eliminating the need to switch between applications. When the call connects, the CRM automatically pops the contact record on screen, providing immediate access to relevant information. During the conversation, the rep captures call notes inline, ensuring accurate and timely data entry. After the call, the disposition dropdown menu triggers predefined workflows such as booking a follow-up meeting, sending a proposal, or marking the lead as unqualified. The call recording is automatically attached to the opportunity record, providing a complete history. This integration saves time by removing the need to alt-tab between the 3CX client and the CRM browser tab, allowing sales reps to focus on conversations and closing deals.

Support team: from inbound ring to ticket resolution

When a customer calls the support queue, the connected CRM performs an immediate phone-number lookup against the contact database. The support agent sees the caller’s open tickets and recent invoices before answering, enabling a more informed response. After the call, the agent logs the call disposition using a dropdown menu, which triggers workflows that either close the ticket or escalate it to a senior engineer based on the issue’s complexity. The connected CRM now includes call-handling data, feeding into the SLA dashboard to report on response times and first-call resolution rates. This integration helps support teams manage cases efficiently and maintain service quality.
