Setting up Cisco CME without the setup command

For versions prior to 8x, the “setup” command has been “depreciated”, but yet it’s still seen on the Cisco router. It literally gets bitchy and basically tells you to eff-off and configure it the more complex way.

Also for $85 in the summer of 2018, it did not include the GUI. While I had an image for the GUI, it was for Release 4. And yet all the nerds love to brag doing everything in terminal  I also defend GUI because it also helps you for the small things, like changing the time at the end of the Daylight time, if you happened to fudge it up, or you want to change the music on hold, stuff like that. I consider the GUI to be the admin, and the terminal for heavier lifting tasks like the routing, etc.

If you so choose to, you’re going to have to set things up line by line.

If you have not assigned a DHCP pool yet, and the VOIP VLAN is separate to your data VLAN; you’re going have to enter (if you don’t have a DHCP server for the sets)

ip dhcp pool ITS*   

network 172.18.2.0 255.255.255.0

option 150 ip 172.18.2.2

default router 172.18.2.2

dns-server 172.18.2.16

* I used “ITS” for the sake of legacy uses because this is what would’ve been entered for the name if you had “setup” still in use.

Network means the server will spit out IP addresses along the network it’s bounded on, by the IP address set up on the interface. I used FastEthernet 0/0 because I felt internal/private LAN should be on the lowest port possible. Your option 150, handles the TFTP server, which will need it’s own discussion later.

Now enter telephony service by entering in

CORE1# telephony-service

Now you want to tell the router how many Cisco SCCP phones you want to have, say

CORE1(telephony)# max-ephones 24

For the number of extensions, double it plus a few more (especially if you want to do paging and Key system functionality)

CORE1(telephony)# max-dn 80

you want to remind the telephony service where its assigned on

CORE1(telephony)# ip source-address 172.18.1.2 port 2000

where port 2000 is the default pipe for Cisco’s SCCP

Do you want to change the line of “Cisco Unified CME” (that on the big CallManager it’s known by “Your Current Options” above the softkeys?

CORE1(telephony)# system-message  ((')) Merry Halloween (('))

CORE1(telephony)# voicemail 8*97

The voicemail button could in theory dial any pre-defined number, and I just used the most likely default carrier number if you don’t have Unity Express installed.

CORE1(telephony)# moh music-on-hold.au

ensure your music-on-hold.au meets Cisco’s spec and it’s living on the flash drive

Entering IP phones is not done in telephony-service at all. This could be because it could be used for SRST functionality, and they kept that prompt at the low level.  You can’t do SRST and CME at the same time.
