India is not on the list is it work ??

The service isn't available in India.

well I use it for India but its just a single call how to make it loop

It's easy to make a loop, the problem is that the service has a number blacklist.
A user can only submit 1 number and if the call is rejected it will send a sms and further calls from the call center.

well its byside call api

It's not a api, byside is in JavaScript to be include in sites.
Byside is used by big brands to get leads.
