Explanation
A URI (Uniform Resource Identifier) dial plan addresses endpoints using a format like 'user@domain' (e.g., [email protected]), which closely resembles an email address. This is commonly used with SIP (Session Initiation Protocol) as a SIP URI. E.164 is the international PSTN numbering standard (e.g., +12025551234) and uses only digits. H.323 is a protocol suite that can use IP addresses or aliases but not email-style URIs. DNS is a resolution system, not a dial plan format itself. The email-like addressing format is the defining characteristic of URI-based dial plans.
