Key Steps in the Porting Process

1. Initiation, Discovery, and Select RDD (Requested Due Date)

• Activities:
  • CallTower collaborates with the customer to create a Letter of Authority (LOA), authorizing the port activity.
  • Customer provides a recent carrier invoice (dated within 30 days) and, if necessary, a Customer Service Record (CSR).
  • Pre-validation of number portability is conducted.
• Requirements:
  • LOA must match billing or CSR information and be signed by an authorized company contact.
  • Toll-free numbers require a separate LOA.
• Duration: Pre-validation ensures smooth processing.

2. Order Submission

• Activities:
  • CallTower gathers all required information and coordinates the order request with relevant teams.
• Duration: 1-2 days.

3. Carrier-to-Carrier Order Submission

• Activities:
  • CallTower submits the port order to a partner carrier, which notifies the old service provider.
  • The new carrier validates the port request based on the LOA.
• Notes:
  • Inconsistent LOA information may result in order rejection.
  • Complex orders (e.g., over 50 DIDs) may take longer.
• Duration:
  • Domestic: 3-15 days.
  • International: 6-45 days.

4. FOC Granted and Port Scheduled

• Activities:
  • The old service provider validates the LOA and grants a Firm Order Commitment (FOC) with a port date.
• Notes:
  • FOC is the expected port date.
• Duration:
  • Domestic: 8-10 days.
  • International: 10-30 days.

---

5. Port Readiness

• Activities:
  • CallTower ensures all systems are ready for the port date.
  • Customers confirm readiness for the FOC date.
• Notes:
  • Changes to port orders require at least 5 business days’ notice and may incur additional fees.
• Duration: At least 5 days before the port date.

---

6. Port Completion

• Activities:
  • On the FOC date, the carrier change is activated, completing the port.
  • Scheduled ports occur automatically, while triggered ports require manual activation by CallTower.
• Timing: Typically occurs Monday-Friday, 8 AM–3 PM local time (varies by carrier).
