Dial Plan Component	Cisco IOS Gateway	Cisco Unified Communication Manager
Endpoint addressing	POTS dial peers for FXS ports and ephone-dn if using UCME/SRST	DN
Call routing and path selection	Dial peers	Route patterns, route groups, route lists, translation patterns, partitions, and calling search spaces
Digit manipulation	Voice translation profiles prefix, digit-strip, forward-digits, and num-exp	Translation patterns, route patterns, and route lists
Calling privileges	COR and COR lists	Partitions, calling search spaces, and FACs
Calling coverage	Dial peers, hunt groups, and call applications	Line groups, hunt lists, and hunt pilots

This information about the PSTN Dial Plan Requirements:

PSTN Requirements	Dial Plan Components
Inbound call routing	· Call routing and path selection for inbound PSTN dial peer to outbound VoIP or local dial peer · Digit manipulation to transform inbound DNIS to endpoints
Outbound call routing	· Call routing and path selection for inbound VoIP or local dial peer to outbound PSTN dial peer · Digit manipulation to transform outbound DNIS to PSTN requirements
Correct ANI presentation	· Digit manipulation to transform ANI meet PSTN requirements
