Formal:
* നിങ്ങൾ അവിടെയുണ്ടോ? (Ningal avideyunndo?) - This is the most literal translation and is appropriate for formal situations.
Informal:
* ഇവിടെയുണ്ടോ? (Ivideyunndo?) - This is a more casual way to say "Are you there?" and is suitable for friends and family.
* നീ ഉണ്ടോ? (Nee undo?) - This is even more informal and is used for close friends and family.
Other options:
* നിങ്ങൾ കേൾക്കുന്നുണ്ടോ? (Ningal kelkkunundho?) - This means "Can you hear me?" and is a good option if you want to make sure the other person is paying attention.
* എന്നെ കേൾക്കുന്നുണ്ടോ? (Enne kelkkunundho?) - This means "Can you hear me?" and is a good option if you want to make sure the other person is paying attention.
It's important to note that the choice of which phrase to use depends on the specific situation and the relationship between the speakers.
