Comma is accepted in speed dial as delimiter and pause.
-Comma used to delineate dial string, FAC, CMC, and post connect digits For post connect digits, commas insert a 2 second delay Commas may be duplicated to create longer delays.
In Cisco Unified Communications Manager (CUCM), SIP dial rules are used to control the interpretation and normalization of dialed digits. The dial rules are applied to digits that are received from a phone, either when the user dials them or when they are received through digit collection. A comma in a SIP dial rule is a delimiter character that separates different dialing patterns.
Answer C is correct: A comma in a SIP Dial Rule pattern that is associated with a Cisco 9971 IP Phone that is registered to Cisco Unified Communications Manager is a delimiter and has no significant dialing impact. It is used to separate different dialing patterns and to make it easier to read the dial rule.
Answer A is incorrect: A comma does not insert a 500-millisecond pause between digits. If a pause is needed, the semicolon character (;) should be used instead.
Answer B is incorrect: A comma does not cause the phone to generate a secondary dial tone. A secondary dial tone is generated by the phone when it receives a dial plan tag that is associated with a specific digit string.
Answer D is incorrect: A comma does not indicate a timeout value of 5000 milliseconds. Timeout values are set in other parts of the CUCM configuration, such as in the route pattern or in the gateway configuration.
Answer E is incorrect: A comma is not an obsolete parameter and will not be ignored. Commas are used to separate different dialing patterns in SIP Dial Rule patterns and are a fundamental part of the dial plan configuration in CUCM.
