there are two kinds of caller id tech from my understanding. if you are using a device imported from usa, it would not work on indian lines. you need to add a converter in the middle. at least that's how it works on regular landlines.
i am planning to buy a cordless phone from usa . i found that on Amazon india we get phones working on 2.4 ghz band . that means there will a lot of disturbance coz the jio router also works on 2.4ghz band . cordless phones from usa work on 1.9ghz band . so i took that decision . i will check and inform you guys whether the caller id feature is working here or not
