### Three Acquisition Paths

| #  | Path             | Description                   |
| -- | ---------------- | ----------------------------- |
| 01 | 140 Series       | Vobiz assigns from pool       |
| 02 | 160 - Scenario 1 | You acquire; Vobiz delivers   |
| 03 | 160 - Scenario 2 | Vobiz acquires on your behalf |

## 2. 140 Series - Vobiz Assigns from Pool

Vobiz assigns a number from its existing pool directly to your TATA DLT ID.

<Info>
  **Pre-requisite** - You must be registered on **TATA DLT specifically** - no other DLT provider is accepted. If not yet registered, Vobiz will guide you through TATA DLT registration before proceeding.
</Info>

### Step-by-Step Process

<Steps>
  <Step title="Share Your TATA DLT ID with Vobiz">
    Provide your registered TATA DLT Entity ID to the Vobiz team. This is the identifier under which the 140 number will be assigned.
  </Step>

  <Step title="Sign the Letter of Intent (LOI)">
    Vobiz issues an LOI. Review and sign it. This formalizes the number acquisition request.
  </Step>

  <Step title="Submit Required Documents">
    Upload your GST certificate, Certificate of Incorporation, and Authorised Signatory KYC documents to Vobiz.
  </Step>

  <Step title="Vobiz Assigns the Number to Your DLT ID">
    Vobiz assigns a 140 number from its existing pool to your TATA DLT ID on the DLT platform.
  </Step>

  <Step title="You Approve the Number on Your DLT Platform">
    Log into your TATA DLT account and approve the number that Vobiz has assigned to you.
  </Step>

  <Step title="Telecom Operator Approves">
    The telecom operator reviews and approves the number assignment once both parties have confirmed.
  </Step>

  <Step title="Add Your Communication Template on DLT">
    Create and submit your communication template on the TATA DLT platform. This defines the type of calls you will be making.
  </Step>

  <Step title="Template Approved - Number is Live">
    Once the telecom operator approves the template, your 140 number is active and ready to use on the Vobiz platform.
  </Step>
</Steps>

### Activation Flow

### Documents Required

* Signed Letter of Intent (LOI format provided by Vobiz)
* GST Registration Certificate

</Info>

### Step-by-Step Process

<Steps>
  <Step title="Technical Discussion with Vobiz - First">
    Before requesting the number from any operator, engage Vobiz to agree on: the data centre where the 160 number will be delivered, the protocol to be used, and any technical constraints. This agreement must be in place before the number is requested.
  </Step>

  <Step title="You Request the Number from Your Operator">
    Approach any telecom operator of your choice and request a 160 series number. Mention that the number will be routed through Vobiz infrastructure.
  </Step>

    The operator will ask for Vobiz's technical information - specifically the IP address and the data centre where the 160 number should be delivered. Vobiz provides this directly to the operator.
  </Step>

  <Step title="You Assign the Number to Vobiz's DLT ID">
    Once the operator has set up the number, assign it to Vobiz's DLT ID (shared by Vobiz with you). This is done on your DLT platform.
  </Step>

  <Step title="Vobiz Approves the Number">
    Vobiz reviews and approves the number assignment on their DLT platform.
  </Step>

  <Step title="Add Your Communication Template on DLT">
    Create and submit your communication template on your DLT platform.
  </Step>

  <Step title="Vobiz Tests the Number">
    Vobiz runs end-to-end tests to confirm the 160 number is routing correctly, audio quality is acceptable, and the integration is working as agreed.
  </Step>

  <Step title="Number is Live">
    Once tests pass, you can start using the 160 number on the Vobiz platform.
  </Step>
</Steps>

  </Step>

  <Step title="Vobiz Approves - Operator Gives Final Approval">

  </Step>

  <Step title="You Create a Communication Template on DLT">
    Create and submit your communication template on the TATA DLT platform. This defines the nature of calls being made.
  </Step>
