How to collect call statistics on the site-catalog of organizations?

Question

Telephony

We are developing an online catalog of organizations, there is a task: to measure the effectiveness of placing information about a company in the catalog.
Naturally: efficiency is measured in calls.
How to measure calls from the site? Call tracking instead of a phone number. 10-20 numbers - 25,000 for connection + 5,000 for a month of service.
But what if there are 1000 organizations in the catalog? not to buy 100 times 20 numbers for 250,000 + subscriber 50,000 per month. Are there any alternative options so that there is a generated phone number for the organization, and when a call is made to it, a request would be automatically sent to the server and redirected to the organization's phone.

Answer 1

1. As already mentioned, your own PBX
2. Contract with a telecom operator, take a pool of numbers.
3. Call by button, you can even display the number on the site, but just make a "call" button
4. Or dynamically give the user some number on the open page, and so each user has a new number each time. PBX integration - the site allows you to identify the company and not the number at once.
5. Based on paragraph 4, you need a pool of numbers that will be equal to the simultaneous number of users on the site, and not the number of companies. Well, if you think about it, even less.
Or do not take any numbers at all, but limit yourself to clause 3 and one number from which the call will go + integration with PBX
PS: integration of the site and PBX in any case

Answer 2

Organize your calltracking, with your own PBX and issuing numbers to organizations.
