Here is as usual a basic configuration that you can perform to enable your CME router.
!
tftp-server flash:<<firmware>>
telephony-service
max-ephones <<X>>
max-dn <<Y>>
load <<phone_type>> <<firmware_load>>
ip source-address 10.1.2.1 port 2000
create cnf-files
transfer-system full-consult
!
ephone-dn <<tag-number>> <dual-line>
number 1234
name technical
!
ephone <<tag-phone>>
mac-address <<AAAA.BBBB.CCCC>>
type <<phone_type>>
button 1:<<tag-number>>
CME provides call processing and enterprises telephony features in a small-to-medium sized network environment, and supports an amount of IP Phones depending the router platform.
To deploy it , you must also install several additional files in the flash and be sure to have the clock set up (it can be done also via the NTP) as it is needed to generate the CNF-Files.
In order to your DHCP to give the TFTP address to your phones , the common configuration is to use the option 150 which is the main and the more expanded concept used for providing your TFTP. It can provide an IP Address as well an array of IP Address.
This is also the code which you are using under IOS configurations.
But in some old implementation , you can find also the option 66 to give the TFTP to the phones . Option 66 is different in the meaning that you must provide a server name so you need to have DNS enabled . Also you can only pass one parameter!!!
So don’t be too disturbed if you see this option 🙂
Hi ,
Just thinking how can we make a pstn emulator in a lab …. First thought is to use a CME router with several T1/E1 , BRI cards to distribute PSTN connection back-to-back to all locations …..
Need to think about it !!!
Very good article on how to maintain the CSS under the SRST mode but it is also true for CCME Config .
