Is it possible for Panasonic PBX KX-NS500RU to play a different melody on one phone, depending on which button was pressed to call?

Question

Telephony

The one who was engaged in the terminal ended his career. I decided to improve my skills, set it up for new users on trifles, a situation arose:
There is a KX-NS500RU, and system phones (kx-dt521)
two people are sitting next to one phone, the phone number is 130.
On the right, the phones have programmable buttons, pressed - called number programmed into the PBX.
I would like to make it so that if from another office they pressed button number one, signed "Gregory", and a call went to number 130, there was a ringtone number 1, and if they pressed button number 2, signed "Mikhail", then a call went to number 130, but ringtone number 2 would be played so that the melody could distinguish who it is calling now. Is it real or do I want too much? Whatever such functionality is called, Google is silent like a partisan due to the fact that I don’t even know how to properly name such a feature.

Answer 1

Extremely unlikely
How will the phone understand that both calls from number 120 to number 130 are for different people?
And what about putting a second phone, even a stupid TS2350 is generally a problem?
Theoretically, if only "Gregory" is sent to 130, and "Mikhail" is allowed to 1130, from there redirect to 130 and if the phone can assign a melody to the incoming number, then it will succeed - but this is a fierce crutch

Answer 2

assign 2 numbers
in the phone settings bind the call to the number, if you can of course

Answer 3

The feature is called " Ring Patterns "
