VOIP Yeahlink T28 Line ringtones

[Dayyan]

Good day
I need assistance. We have had issues with the yeahlink t26 phones in our office that continuously would require rebooting.

We have now acquired T28's. The issue is that we have 2 lines that we make use of. Lets call them Line 1 and Line 2.

These are 2 different numbers that outsiders call. The t26 allowed provision for each line to have a distinct ringing tone so that we in office would know which call it was.

The T28 seems to not have this functionality as I have gone through the settings already.

Kindly assist
