How easy is it to track calls from a website?

Question

Telephony

Is there a service or some solution to simply transfer data on the achievement of the goal to Ya.Metrika, so that without newfangled substitutions of numbers, end-to-end analytics, etc.?
PS I would like a more budgetary way and not overpay for unnecessary features :)

Answer 1

Calls

Answer 2

on sending the application form, you can hang an event about the achievement of the goal

Answer 3

how do you want the call to be tracked if it goes to the same number?
On the basis of what there should be identification of the client that?

Answer 4

Only different numbers, each goal has its own, otherwise you can’t make out ....

Answer 5

Virtual PBX is used for this.
In fact, this is a separate number available only on the site, the implementation is already a matter of 10.
Up to dynamic for an advertising company.
Here already from the task.
