10 Steps to Configure Cisco Call Manager Express

Simplify the transition from legacy telephony to unified communications and collaboration at the branch office. Cisco Unified Communications Manager Express is a customizable solution that is affordable, simple to deploy, and scalable. Provide localized call control, mobility, and conferencing alongside data applications on Cisco Integrated Services Routers.

Step 1. Configure a Switch Trunk Port

  • SwitchA(config-if)#switchport trunk encapsulation dot1q
  • SwitchA(config-if)# switchport mode trunk
  • Step 1.1. Create VLAN

  • SwitchA# configure terminal
  • SwitchA(config)# vlan 10
  • SwitchA(config-vlan)# name VOICE
  • SwitchA(config-vlan)# exit
  • SwitchA(config)# vlan 50
  • SwitchA(config-vlan)# name DATA
  • Step 1.2. Assign Switchport to a VLAN

  • SwitchA# configure terminal
  • SwitchA(config)# interface fa0/10
  • SwitchA(config-if)# switchport mode access
  • SwitchA(config-if)# switchport access vlan 50
  • Step 1.3. Assign Voice and Data VLANs

  • SwitchA# configure terminal
  • SwitchA(config)#interfac range fa0/1 - 4
  • SwitchA(config-if-range)# switchport mode access
  • SwitchA(config-if-range)# switchport access vlan 50
  • SwitchA(config-if-range)# switchport voice vlan 10
  • Step 1.4. Configure a Trunk to the CME Router

  • SwitchA# configure terminal
  • SwitchA(config)# interface fa0/20
  • SwitchA(config-if)# description CONNECTION TO ROUTER-ON-A-STICK CME ROUTER
  • SwitchA(config-if)# switchport trunk encapsulation dot1q
  • SwitchA(config-if)# switchport mode trunk
  • Step 2. Configure Inter-VLAN Routing

  • Router# configure terminal
  • Router(config)# interface fa0/0
  • Router(config-if)# no ip address
  • Router(config-if)#exit
  • Router(config)# interface fa0/0.10
  • Router(config-subif)# description ROUTER INTERFACE FOR VOICE VLAN
  • Router(config-subif)# encapsulation dot1q 10
  • Router(config-subif)# ip address 172.16.1.1 255.255.255.0
  • Router(config-subif)# ip helper-address 172.16.2.5
  • Router(config-subif)#exit
  • Router(config)# interface fa0/0.50
  • Router(config-subif)# description ROUTER INTERFACE FOR DATA VLAN
  • Router(config-subif)# encapsulation dot1q 50
  • Router(config-subif)# ip address 172.16.2.1 255.255.255.0
  • Step 3. Configure a Router-Based DHCP Server

  • RTR# configure terminal
  • RTR(config)# ip dhcp excluded-address 172.16.1.1 172.16.1.9
  • RTR(config)# ip dhcp excluded-address 172.16.2.1 172.16.2.9
  • RTR(config)# ip dhcp pool DATA_SCOPE
  • RTR(dhcp-config)# network 172.16.2.0 255.255.255.0
  • RTR(dhcp-config)# default-router 172.16.2.1
  • RTR(dhcp-config)# dns-server 4.2.2.2
  • RTR(dhcp-config)# exit
  • RTR(config)# ip dhcp pool VOICE_SCOPE
  • RTR(dhcp-config)#netowrk 172.16.1.0 255.255.255.0
  • RTR(dhcp-config)# default-router 172.16.1.1
  • RTR(dhcp-config)# option 150 ip 172.16.1.1
  • RTR(dhcp-config)# dns-server 4.2.2.2
  • Step 4. Set the Clock of a Cisco Device with NTP

  • RTR# configure terminal
  • RTR(config)# ntp server 64.209.210.20
  • RTR(config)# clock timezone Cairo +2
  • Step 5. Install CME Files into Flash Memory

  • CME_Voice# archive tar /xtract tftp://172.16.2.5/ flash:
  • Step 6. Configure Router-Based TFTP Services for IP Phone Firmware Files

  • CME_Voice# configure terminal
  • CME_Voice(config)# tftp-server flash:/phone/
  • Step 7. Configure the Cisco Unified CME System-Level Functions

    Provision CME Phone and Directory Number:

  • CME_Voice# configure terminal
  • CME_Voice(config)# telephony-service
  • CME_Voice(config-telephony)# max ephone x
  • CME_Voice(config-telephony)# max dn x
  • Configure CME for Firmware Loads:

  • CME_Voice# configure terminal
  • CME_Voice(config)# tftp-server flash:/phone//
  • Set the firmware load for each phone:

  • CME_Voice# configure terminal
  • CME_Voice(config)# load
  • Step 8. Source IP Address Information

  • CME_Voice# configure terminal
  • CME_Voice(config)# telephony-service
  • CME_Voice(config-telephony)# ip souerce address 172.16.1.1
  • Step 9. Generation IP Phone Configuration File

  • CME_Voice# configure terminal
  • CME_Voice(config)# telephony-service
  • CME_Voice(config-telephony)# creat cnf-files
  • Step 10. Verify Files Served by the CME TFTP Service

  • CME_Voice# show telephony-service tftp-bindings
