Enabling calling on DND numbers is a two-step process.
Step 1: We need to get a screenshot of a lead in your CRM or lead management system which should have captured the lead name, URL, phone number, and company name are visible. In the absence of a CRM screenshot, the regulators approve any of the below sample document 

1. Application hard copy:- Subscription details to be clearly mentioned with name, phone number, and signature.
2. Transaction slip:- Invoice or payment slip which must not be older than 6 months & must contain either portal link (URL) or company name/logo along with customer details.
3. Mail entries captured in SQL 

Once we have received the opt-in, It will flow through an internal approval process. Post-approval, we can proceed with step 2.

Step 2:  We need a signed and stamped copy of your letterhead where the below text is mentioned.
