Exam 350-801 topic 1 question 27 discussion

Should be C 15 second

^update. Finding 15 sec is correct.

When matching a variable-length pattern, the Cisco Unified Communications Manager does not know when dialing is complete, so it will wait for 15 seconds by default before processing the call. This post-dial delay can be reduced or eliminated as follows:  Reduce the Cisco CallManager service parameter called the T302 Timer to allow earlier detection of the end of dialing. However, do not set this timer to less than 4 seconds, to prevent premature transmission of the call before the user finishes dialing.  Configure a second route pattern, followed by the pound sign (#) wildcard, such as 9.011!# for North America or 0.00!# for Europe. Then educate users that they can indicate end of dialing by terminating the number with the # key. This action is analogous to pressing the Send button on a cell phone.

Per the CCNP and CCIE Collaboration Core CLCOR 350-801 Official Cert Guide: Chapter 19: Configuring Globalized Call Routing in Cisco Unified Communications Manager: When matching a variable-length pattern, the Cisco Unified Communications Manager does not know when dialing is complete, so it will wait for 15 seconds by default before processing the call. A is the correct answer

A 15s is correct

15 is correct

T302 timer is set by default to 15 seconds

15 sec by default

default it 15 sec but it can be modified.

15 sec is correct, this is choise A

In the current SRND, the CUCM Service Parameter default is set to 15000, which is 15 seconds. Even when validating on the version of CUCM this test covers, hovering the mouse above the default T302 Timer value shows this javascript value, "javascript:getHelp('TimerT302_msec'), where msec = milliseconds. 15000 milliseconds to seconds converted is 15 seconds, respectively.

15 sec is correct, this is choise A

15 seconds

Now A is 15 second!

Answer C This is T.302 Timer, no matter if SCCP or SIP T302 Timer: Required Field This parameter specifies an interdigit timer for sending the SETUP ACK message. The timer restarts each time Cisco CallManager receives a digit. When this timer expires, Cisco CallManager routes the dialed digits. This is a required field. Default: 15000 ms Minimum: 3000 ms Maximum: 75000 ms If the user dials digits but then does not press the Dial softkey or the # key, the phone will wait for inter-digit timeout (15 seconds by default) before sending a SIP INVITE message to Unified CM. https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/srnd/collab10/collab10/dialplan.html

Should be C

The valid delay is 15 seconds
