Which statement about what happens to a Cisco IOS SIP VoIP dial-peer that never received any responses to its out-of-dialog OPTIONS ping is true?
Correct Answer: A
Explanation/Reference:
Explanation:
You can check the validity of your dial peer configuration by performing the following tasks:
* If you have relatively few dial peers configured, you can use the show dial-peer voice command to verify that the configuration is correct. To display a specific dial peer or to display all configured dial peers, use this command. The following is sample output from the show dial-peer voice command for a specific VoIP dial peer:
router# show dial-peer voice 10
VoiceOverIpPeer10
tag = 10, dest-pat = \Q',
incall-number = \Q+14087',
group = 0, Admin state is up, Operation state is down
Permission is Answer,
type = voip, session-target = \Q',
sess-proto = cisco, req-qos = bestEffort,
acc-qos = bestEffort,
fax-rate = voice, codec = g729r8,
Expect factor = 10,Icpif = 30, VAD = disabled, Poor QOV Trap = disabled, Connect Time = 0, Charged Units = 0 Successful Calls = 0, Failed Calls = 0 Accepted Calls = 0, Refused Calls = 0 Last Disconnect Cause is "" Last Disconnect Text is "" Last Setup Time = 0
* To show the dial peer that matches a particular number (destination pattern), use the show dialplan number command. The following example displays the VoIP dial peer associated with the destination pattern 51234:
router# show dialplan number 51234

VoiceOverIpPeer1004
tag = 1004, destination-pattern = \Q+1408555....',

group = 1004, Admin state is up, Operation state is up
type = voip, session-target = \Qipv4:1.13.24.0',
ip precedence: 0 UDP checksum = disabled
session-protocol = cisco, req-qos = best-effort,

fax-rate = voice, codec = g729r8,
Expect factor = 10, Icpif = 30,
VAD = enabled, Poor QOV Trap = disabled
Connect Time = 0, Charged Units = 0
Successful Calls = 0, Failed Calls = 0
Accepted Calls = 0, Refused Calls = 0
