Explore the different types of CRMs compatible with 3CX for seamless telephony integration. Find tailored solutions for your SME's communication needs.
Selecting the right customer relationship management (CRM) platform to work alongside 3CX is crucial for achieving seamless telephony integration and efficient call handling. 3CX supports a wide range of CRM types, from well‑known cloud systems to on‑premise databases and industry‑specific solutions. Popular cloud‑based CRMs such as HubSpot, Salesforce, Zoho and Microsoft Dynamics 365 can be integrated using 3CX’s built‑in connectors or standard APIs, providing click‑to‑call, screen‑pops, automatic call logging and call recording links. Many SMEs also rely on more straightforward contact management tools or helpdesk platforms, which can often be connected using generic CRM templates, webhooks or REST APIs. This flexibility allows businesses to maintain their preferred CRM while enhancing it with telephony features that streamline daily operations.
Beyond mainstream platforms, 3CX is compatible with various on‑premise and bespoke CRMs through ODBC, server‑side integrations and custom development. This is particularly valuable for organisations that hold sensitive data in local databases or use vertical‑market systems such as legal, healthcare, automotive or property management software. Integration options include synchronising caller details, logging interactions against customer records and routing calls based on CRM data. Whether the CRM is cloud‑hosted, server‑based or custom‑built, 3CX’s integration framework supports a wide spectrum of technologies, enabling SMEs to unify their communications and customer data. By choosing a CRM that offers an open API or supported connector, businesses can achieve a seamless link between telephony and customer records, improving response times, reporting accuracy and overall customer experience.

3CX offers native integration for many leading cloud CRMs, which is often the simplest route for SMEs. These integrations typically provide click‑to‑dial from within the CRM, automatic contact matching when a call arrives, and call logging with notes and call duration. For many businesses, this level of integration is sufficient to improve productivity and ensure consistent record‑keeping.
For organisations using on‑premise or legacy CRMs, 3CX supports connectivity through ODBC, server‑side scripting and API‑based connectors. This allows integration with SQL databases, proprietary systems and older applications that remain central to business operations. Features such as caller identification, activity logging and call history can still be achieved, even when the CRM is not cloud‑based.
Where a CRM is highly specialised or custom‑built, 3CX’s generic CRM integration and REST interface enable tailored solutions. Developers can map fields, define triggers and control how call data is exchanged, ensuring the telephony system aligns with specific workflows, compliance requirements and reporting needs.
