Understanding Port Types
DEL (Direct Exchange Line) — Simple Port
Select DEL for:
Single-line PSTN services
Standard telephone services
Numbers without complex features
DID/DDI (Direct Inward Dialling) — Complex Port
Select DID/DDI for:
Number ranges or blocks
Numbers with complex services
PABX or private system numbers
Numbers that allow direct dialling without operator intervention
Important: If porting a number block, you must port the full range or have your current carrier disassociate the specific numbers you wish to port.
