1. Key Requirements at a Glance
PE Certificate and LOI are client-arranged prerequisites. The PE (Principal Entity) Certificate must be obtained from either TATA Teleservices or Airtel, and an LOI (Letter of Intent) must be signed by the Principal Entity. Both are mandatory for procuring either a 140 or a 160 DID and should be arranged before initiating the process. Both series also carry a 12-month lock-in period from the date of allocation.
2. Terminology
The DLT portal and the carrier use specific terms. This is what each one means in the context of your provisioning request.3. Process for 140 DID
The 140 series follows a DLT header registration route via your Telemarketer (TM) ID.1
Principal Entity signs the LOI
The Principal Entity (PE) signs an LOI (Letter of Intent) authorising procurement of the 140 DID. This is mandatory before the number can be procured.

Principal Entity approves the header
The Principal Entity reviews and approves the header registration from their side.

Carrier approval
Once PE approval is confirmed, the header is submitted for approval at the carrier (TATA / Airtel) end.

DID allocated to your Vobiz account
Once both the PE approval and the carrier approval are complete, the 140 DID is allocated to your Vobiz account.

Start outbound calling
You can now begin making outbound calls using the allocated 140 number.

DID allocated to your Vobiz account
Once the DLT registration and approvals are complete, the 160 DID is allocated to your Vobiz account and outbound calling can begin.
