Telephony + CRM: how to make sure no call gets lost

A missed call is a lead that went to a competitor. How to connect IP telephony to Bitrix24 or amoCRM, what it gives the sales team, and how it works in a contact centre with 150 operators.

In many companies I start working with, calls live separately from the CRM. Managers call from personal phones, nobody has listened to the recordings, and nobody counts missed calls. The owner learns about a lost customer when that customer has already bought from a competitor.

What is wrong with "just a phone"

  • Missed calls are invisible. There is no list of who called and who was never called back.
  • The customer belongs to the manager, not the company. An employee leaves, and their contact list leaves with them.
  • Nothing to check. Without recordings you cannot sort out a dispute or train a newcomer on real conversations.
  • No statistics. How many calls a day, how long customers wait, which manager is overloaded — nobody knows.

How the setup works

The scheme is almost always the same, only the components change:

  1. Numbers. Landline or mobile numbers are connected through a SIP operator, and the company's number stays with the company.
  2. PBX. Cloud or your own (Asterisk, Issabel) — it routes calls to queues and operators.
  3. Connector. It links the PBX to the CRM: for example, ITGRIX for Bitrix24 and amoCRM.
  4. CRM. Every call shows up in the customer's card: who called, who answered, the recording.

What the sales team gets

  • New number, new deal. A call from an unknown number creates a lead with an owner straight away.
  • The call reaches the right manager. The PBX connects a returning customer to the person who handles them.
  • A missed call becomes a task. The CRM sets a call-back task and reminds about it.
  • Recordings in the card. The manager listens to calls in the same place they see the deal.
  • Reports. Operator load, missed calls, response time — without counting by hand.

Example: the Nutva contact centre

Nutva has two sales lines, and calls for each must reach the right operators and the right pipeline at once. We built telephony on Issabel/Asterisk with the ITGRIX connector, wrote our own module that routes deals between pipelines, and set up the FOP2 operator panel and a call recording archive.

The contact centre now has 150 operators, and the conversion of enquiries into deals has grown by 45%.

How long it takes

A typical telephony-to-CRM connection takes 1–2 weeks: choosing the scheme and numbers, setting up the PBX and the connector, routing, testing on real calls, training. Large contact centres with their own routing are done in stages.
