Important testing commands on the router

To simulate test outbound call on the router- R1#show dialplan number <test number> This command will show you which dialpeer will be hit if this number is dialed. Example- RTR1#show dialplan number 911 Macro Exp.: 911 VoiceOverIpPeer15400 peer type = voice, system default peer = FALSE, information type = voice, description = `CME1-TO-CME2-911', tag = 15400, destination-pattern = `911$', voice reg type = 0, corresponding tag = 0, allow watch = FALSE answer-address = `', preference=1, To test translation rules- R1#test voice translation-rule <rule#> <number to translate> Example voice translation-rule 1  rule 4 /^914102850417/ /DEAD/  rule 5 /^91410915..../ /DEAD/  rule 36 /9011204/ /000204/  rule 37 /9011226/ /000226/ RTR1#test voice translation-rule 1 914102850417   Matched with rule 4 Original number: 914102850417 Translated number: DEAD Original number type: none Tr

Three-step DHCP basic configuration on a router

Basic configuration of DHCP on a router- By deafult, DHCP server and relay agent service is enabled on a router, hence, we do not need to start it. 1. Instead of mentioning the range which should be assigned as IP address for the devices using your DHCP server, we mention the address it should exclude to assign to the devices- R1(conf)#ip dhcp excluded-address <range of IP address> example R1(conf)#ip dhcp excluded-address 142.100.10.20 142.100.10.50 R1(conf)#ip dhcp excluded-address 142.100.10.80 142.100.10.254 This means only range 142.100.10.1-10 and 142.100.10.51-79 is available for the devices. 2. Configure the DHCP Pool R1(conf)#ip dhcp pool POOL1  ---- define the name of the pool R1( dhcp-config)# network 142.100.10.0 255.255.255.0 -- define the IP&mask of the DHCP pool's network R1( dhcp-config)#default router 142.100.10.20  -- define default gateway R1( dhcp-config)#option 150 142.100.10.20 -- define TFTP address 3. Configure IP helper Addres

NTP Configuration on router

NTP configuration on the router is pretty simple. Make your router as NTP server - 1. Set the clock on the router. You can use "clock" command in the privilege mode to set the time. 2. In order to configure it as master, configure the router as - "ntp master <stratum>". The stratum n umber from 1 to 15. Indicates the NTP stratum number that the system will claim. This will make your router as master. 06:49:10.078 UTC Sun Mar 22 2015 ntp master 5 NTP client configuration- 1. Configure ntp master server address in the privilege mode- ntp server <ip address of ntp master> Validating NTP associations - Check its clock R1#show clock 06:58:15.888 UTC Sun Mar 22 2015 R1#show ntp associations   address         ref clock       st   when   poll reach  delay  offset   disp *~157.26.1.254    .LOCL.           1   1021   1024   377  0.706  -0.926  0.054  * sys.peer, # selected, + candidate, - outlyer, x falseticker, ~ configured

web dialer configuration on CUCM

Web Dialer is the feature which helps you to dial through web using your IP Phone. Its configuration is pretty simple as the application user is auto created. All you need to do is- 1. Enable the web dialer service. 2. Go to Service Parameters > web dialer - Provide CTI Manager Primary and Secondary Servers. This would require restart of the service. 3. Assign "Standard CTI Enabled" user group on your End User Configuration. Your end user should have your IP Phone as controlled device. 4. Access web dialer service : https://<IP-Address-CTI-Manager>/webdialer/WebDialer 5. Enter the username and password and you are done. Enjoy the web dialer service!
