The port process step by step
A managed handoff from your old carrier to Teloz with no service interruption.
- 1
Step 1Inventory and LOA
Teloz collects the carrier bill, account numbers, and a signed Letter of Authorization.
- 2
Step 2Submission
The port request goes to the losing carrier with the FOC (Firm Order Commitment) date, following rules outlined in the FCC number porting guide.
- 3
Step 3Parallel provisioning
Extensions, queues, voicemail, and routing are built in Teloz before cutover.
- 4
Step 4Cutover
On FOC day, the number activates in Teloz. Inbound switches instantly; outbound can continue from the old carrier until verified.
- 5
Step 5Verification and backout
Teloz runs test calls and keeps a backout path open for 24–48 hours.
Avoiding the common porting failures
Most port rejections come from three problems. Teloz checks all three before submitting — because a rejection restarts the FOC clock and costs days.
For toll-free, RespOrg changes are handled inside the SMS/800 database; for international, each country has a different release process — Teloz manages end-to-end.
When a port can't go through
Some numbers can't be ported. Teloz flags these in the inventory review so you can decide on the next best move.
- Pre-paid mobile DIDs in certain markets
- Numbers locked by the losing carrier
- Numbers where the account is in dispute
