# Number porting and cutover

Number porting and cutover One page pulled from the Canon rooms named in the source column. Open the room before you quote a number in a design. This is not a copy of a Cisco document. Check What the room says Source What is a port? A transfer from the losing carrier to the winning carrier. [cite:1] T6-R06-number-porting-cutover.html What two documents prove you may port? A bill from the last 30 days and an LOA or eLOA. [cite:1] T6-R06-number-porting-cutover.html How many numbers does one license allow? One. The port count cannot exceed purchased licenses. [cite:1] T6-R06-number-porting-cutover.html When is the requested date real? When the losing carrier returns an FOC. Until then it is a request. [cite:1] T6-R06-number-porting-cutover.html What happens to numbers on the same account? They port together, even if they were typed on different orders. [cite:1] T6-R06-number-porting-cutover.html How do you prove you can still edit the order? FOC has not arrived. After FOC, Control Hub edits stop and PTS is the path. [cite:1] T6-R06-number-porting-cutover.html What evidence shows a port-out was ignored? One business day passed on PSTN & Routing → PSTN Orders. The article says the request is then accepted automatically. [cite:2] T6-R06-number-porting-cutover.html Back to the lab · Cheat Codes
