Types of Ports

Simple Port

As defined by the FCC, simple ports: 

  1. Do not involve unbundled network elements 

  2. Involve an account only for a single line

  3. Do not include complex switch translations (e.g., Centrex, ISDN, AIN services, remote call forwarding, or multiple services on the loop/line) 

  4. Do not include a reseller.

Non-Simple Port

A non-simple port is any port that does not qualify as a simple port. Ports with more than 20 numbers and multi-line accounts qualify as non-simple ports and may require project management.
Contact Telnyx for details before submitting the LSR.

Please note that for non-simple ports Telnyx requires all telephone numbers to be listed on a separate, clean sheet of the LSR in a 10-digit format.

Rejected LSRs

Telnyx will provide a “reject” notice within 48 business hours

LSRs received after 2 PM CT will be considered received on the following business day.

Multi-line accounts may require project management and a longer interval.

Firm Order Confirmation

FOC will be issued if Telnyx determines, based on LSOR standards, that the LSR has no errors or discrepancies.

Telnyx does not accept same-day FOCs.

FOC is valid for 10 business days. The order will be canceled if the number is not activated in NPAC by the end of the third business day.

Cancellations or Reschedules

Cancellation or reschedule requests must be received by 2 PM CST the day before the scheduled port date.
