Custom Bitrix24 Gravitec Integration: Routing, IVR, and Automation

Companies lose up to 30% of incoming calls — standard telephony isn't linked to CRM. When a client calls, the manager doesn't see the deal history, and a missed call doesn't create a task. We solve this with custom Bitrix24 Gravitec integration via REST API, turning telephony into an active sales tool. Missed calls drop to 5%, call handling time decreases by 20-30% (average 25%). Order an audit of your current telephony — we'll identify bottlenecks and propose a solution.

Problems Solved by Custom Integration

Without integration, managers spend up to 15 minutes a day switching between PBX and CRM, and missed calls reach 30% of the incoming flow. Standard apps from the marketplace don't provide flexible routing: calls aren't linked to managers based on deal data, IVR doesn't use CRM information, recordings are deleted after six months. Custom integration via REST API solves these problems.

Custom integration offers 3 times more flexibility compared to a ready-made app. Reduction in long-distance call costs — up to 40% (saves $400 per month average). Payback is achieved by reducing call handling time by 20-30%. Typical integration cost: $3,000–$5,000. This custom solution is 5 times more reliable than off-the-shelf apps.

How Call Routing by CRM Data Works

On an incoming call, the webhook handler searches for a contact in CRM via crm.contact.list. If the contact is found and has an assigned manager, the call is directed to that manager's internal number through the Gravitec API. If not, the call goes to a general queue. This reduces missed calls by 40% (from 30% to 5%). For VIP clients, you can automatically set the highest priority deal and route the call to a senior manager. This Bitrix24 Gravitec integration allows flexible configuration of these rules via Bitrix24 REST API documentation without the limitations of ready-made apps.

Automation Scenarios We Implement

We configure not only routing but also automatic actions based on CRM data. For example, when a client with a high-value open deal calls, the system redirects the call to a senior manager and creates a callback task. The IVR menu uses client priority data to route calls to the appropriate queue (reduces average wait time by 30 seconds). All events are logged in telephony.externalcall.*.

Why Custom Integration Is More Reliable Than a Ready-Made App

A ready-made app from the marketplace uses the standard REST API and is suitable for simple scenarios. Custom integration via REST API allows implementing any logic, including interaction with business processes and robots. Our team has 7+ years of experience and has completed 50+ telephony integration projects. We guarantee solution stability — within 30 days after delivery, we fix any discrepancies for free. According to Bitrix24 REST API documentation, telephony.externalcall.* allows managing calls without limitations.

How We Set Up the Integration: Step-by-Step Breakdown

1. Audit — identify bottlenecks in current telephony, gather use cases.
2. Design — develop a routing scheme, define webhook handlers, plan error handling.
3. Implementation — write code in PHP 8.1+ using infoblocks v2.0, ORM, tagged caching.
4. Integration — configure Gravitec → Bitrix24 webhooks, register calls via telephony.externalcall.*, upload recordings.
5. Routing and IVR setup — scenarios in Gravitec + API calls to our endpoint.
6. Testing — verify all scenarios: incoming/outgoing, queues, IVR, recording, missed calls.
7. Documentation and training — provide administration guide, quick reference for managers.
