3CX CRM Integration for Houston Businesses
Connect your 3CX phone system to HubSpot, Salesforce, ConnectWise, and Microsoft 365. Automatic call logging, screen pop on inbound calls, and click-to-dial from your CRM.
Your Phone System and CRM Are Separate Islands
Your sales team answers 40 calls a day and manually logs a fraction of them. The ones they do log get entered after the call, from memory, with incomplete notes. By end of week, a third of the week's call activity is either missing from your CRM or recorded with the wrong contact.
Your service desk picks up calls from clients whose names they don't recognize, spends 30 seconds looking up the account before they can start helping, and still sometimes pulls up the wrong record. That delay multiplied across hundreds of calls per week is real money.
3CX's native CRM integrations solve both problems. Call data flows into your CRM automatically. Contact records surface before the first ring finishes. Your team answers calls with context instead of uncertainty.

3CX + HubSpot
The 3CX HubSpot integration surfaces contact records on every inbound call before the agent picks up. Calls are logged automatically to the contact timeline with duration, direction, and recording link. Outbound calls can be initiated directly from HubSpot contact records via click-to-call.
- Inbound screen pop with contact name and deal status
- Auto-logged calls on contact timeline
- Click-to-dial from HubSpot contact records
- Missed call tasks created automatically
- Recording links attached to call log entries


3CX + Salesforce
Salesforce users gain the same screen pop and call logging functionality, with the addition of automatic activity record creation on Leads, Contacts, and Accounts. The integration works with both Salesforce Classic and Lightning Experience and doesn't require a third-party CTI adapter.
- Screen pop on Lead, Contact, Account, and Opportunity records
- Activity records created on every call
- Click-to-dial from any Salesforce record
- Call notes attached to activity from 3CX web client
- Supports Salesforce Classic and Lightning
3CX + ConnectWise Manage
Houston TechSys runs ConnectWise internally — we've built and refined our 3CX integration with ConnectWise Manage for MSP environments specifically. Inbound calls from clients show the company record, open tickets, and the caller's contact history. Calls can be logged as time entries directly from 3CX.
- Company record screen pop for inbound calls
- Open ticket count displayed on screen pop
- Calls logged as time entries in ConnectWise
- New service tickets created from missed calls
- Contact lookup against ConnectWise directory


3CX + Microsoft 365
The Microsoft 365 integration pulls your Outlook contacts into 3CX for caller ID resolution. Calls can be logged to Outlook calendar as appointments, and the integration supports Microsoft Teams presence sync — your Teams status reflects your 3CX call state in real time.
- Outlook contact directory sync for caller ID
- Call log entries written to Outlook calendar
- Microsoft Teams presence synchronization
- Shared contact directories across 3CX and Teams
- Exchange calendar used for availability routing
Custom and Proprietary CRM Integrations
If your business uses a CRM not in the list above — Zoho, Pipedrive, ServiceNow, Autotask, or a custom-built system — Houston TechSys can often build a custom integration using 3CX's REST API and webhook framework. We'll assess feasibility during discovery and quote accordingly.
Zoho CRM
3CX native Zoho integration with screen pop, call log, and click-to-dial. Available for Zoho CRM, Zoho Desk, and Zoho Bigin.
Autotask / Datto
PSA integration for MSPs. Calls from managed clients populate ticket data and time entry logs.
Custom REST Webhooks
If your CRM exposes a REST API, we can push call data into it using 3CX's webhook framework. Scoped per project.
Frequently Asked Questions
Does CRM integration require a specific 3CX license tier?
CRM integrations are available on 3CX's Standard and Pro licenses. Some integrations (like Microsoft Teams sync) require the Pro tier. We'll confirm license requirements during scoping.
How long does a CRM integration take to configure?
Most standard CRM integrations can be configured and tested in a half-day. Custom REST integrations take longer — typically 2–5 business days depending on the CRM API complexity.
Will integration slow down the phone system?
No. CRM integrations run asynchronously. A failed CRM lookup won't prevent calls from routing. Screen pop may not appear if the CRM is unreachable, but call handling is unaffected.
Can agents see CRM data on mobile devices?
Yes. The 3CX iOS and Android apps support CRM screen pop when the device is connected to the internet. The feature uses the same integration as the desktop client.
