CallTower DID Porting Timelines and Process
This document outlines the steps, timelines, and requirements for porting Direct Inward Dialing (DID) numbers with CallTower, ensuring a smooth transition between carriers.
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), authorising 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 authorised 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).
Summary of Timelines
- Domestic Porting: 8-15 days (average).
- International Porting: 10-45 days (depending on complexity).

CallTower’s DID porting process ensures a seamless transition with clear steps, timelines, and support to minimise disruptions.
