CME – How to collect Debug Logs

====================> How to enable Voice call Debug Filtering

Voice call debug Filtering
————————–
First configure the filter  using “call filter match-list <tag> voice” and then
use the filter as a debug condition using “debug condition match-list <tag>

call filter match-list <tag> voice
incoming calling-number <pattern>
incoming called-number <pattern>
incoming dialpeer <tag>
incoming media local ipv4 <ip address>
incoming media remote ipv4 <ip address>
incoming port
incoming signaling local ipv4 <ip address>
incoming signaling remote ipv4 <ip address>
incoming secondary-called-number <pattern>
incoming uri <pattern>

outcoming calling-number <pattern>
outcoming called-number <pattern>
outcoming dialpeer <tag>
outcoming media local ipv4 <ip address>
outcoming media remote ipv4 <ip address>
outcoming port
outcoming signaling local ipv4 <ip address>
outcoming signaling remote ipv4 <ip address>
outcoming secondary-called-number

debug condition match-list <call filter tag>

===================> CME – How to collect debugs in SYSLOG Server

Collecting debugs in Syslog server
———————————-
Router#configuration terminal
Router(config)#no logging console
Router(config)#ntp update-calendar
Router(config)#ntp server <IP Address of NTP Server>
Router(config)#service timestamps log datetime msec
Router(config)#logging <Hostname or IP Address of SYSLOG server>
Router(config)#exit
Router#

Note: NTP configuration is required when the problem involves multiple gateways.

=========================> Collect debug logs in Router Logging

Collecting debugs in Router logging buffer
——————————————
Router#configuration terminal
Router(config)#no logging console
Router(config)#ntp update-calendar
Router(config)#ntp server <IP Address of NTP Server>
Router(config)#service timestamps debug datetime msec
Router(config)#logging buffered <buffer size> debugging
Router(config)#service sequence
Router(config)#no logging rate-limit
Router(config)#exit
Router#

Note: NTP configuration is required when the problem involves multiple gateways.
