Shall I buy PSTN phone Number Using scholarship account subscription

Hello Soundhar M, to purchase phone numbers in Azure Communication Services, you need to have a subscription that supports phone number capabilities. Currently, phone number capabilities are available in the following subscription offers:

• Microsoft Customer Agreement (Field and Customer Led)
• Modern Partner Agreement (CSP)
• Enterprise Agreement
• Pay-As-You-Go

Subscription eligiblity offers changes based on the country in which you're trying to puchase the phone number. You would want to keep a tab on this page -- https://video2.skills-academy.com/en-us/azure/communication-services/concepts/numbers/phone-number-management-for-united-states.
