How to configure UCCX Simple Auto Attendant

How to configure UCCX Simple Auto Attendant

I  am going to configure UCCX and CUCM for simple Auto Attendant using inbuilt script (aa.aef) in Cisco UCCX. I am not making any restriction so I am not using CSS and Partition to make it very simple .

we need to go through following steps .

  • Creating UCCX Call Control Group (CTI Ports in CUCM)
  • Adding  UCCX Script Application
  • Adding UCCX Trigger (CTI Route Point in CUCM)
  • Make a Test Call to Auto Attendant

Before going above steps  UCCX basic configuration  should be done as AXL, JTAPI and RMCM integration. As it is the POST  UCCX configuration after installation  .

PID: CISCO2811 , VID: V05 , 

NAME: “VWIC2-1MFT-T1/E1 – 1-Port RJ-48 Multiflex Trunk – T1/E1 on Slot 0 SubSlot 0“, DESCR: “VWIC2-1MFT-T1/E1 – 1-Port RJ-48 Multiflex Trunk – T1/E1”

 

Show inventory command shows you the location installed VVIC card in our case it is installed on Cisco Router Slot 0.

Call is connecting but phone is not ringing CCIE Voice LAB setup

I was trying to build the CCIE Voice lab for practice and learn Cisco Voice .I configured T1 connection from HQ site to PSTN T1 with tree channels .HQ site I had to configure HQ site MGCP with using three channels .I configured the MGCP on T1 line and it was registered in CUCM. I  configured T1 line channels manually because i wanted to use 3 channels . as soon as i was applying the registering on cucm it was making it 24 channels . but T1 channels was up and multiple frame was established .when i was calling from HQ site to PSTN phone On the phone call was showing connected but PSTN phone was not ringing. I did the mistake on my PSTN router I did not configured following parameter. so it was not ringing my phone .

dial-peer voice 1 pots
incoming called-number .
direct-inward-dial

Below was the my configuration on HQ site and PSTN site .

How to configure cisco router as NTP server

How to configure Cisco router as NTP server

1- you have to obtain public NTP server addresses from www.ntp.org
2-  configure you router with NTP server IP

GK_RTR#configure terminal
GK_RTR(config)#ntp server 64.209.210.20
GK_RTR(config)#ntp source lo
GK_RTR(config)# ntp master
GK_RTR(config)#clock timezone ARIZONA -7

3- Verifying NTP Configurations

GK_RTR#show ntp associations
GK_RTR#show clock

4- After you configure the Cisco router to synchronize with an NTP server, you can configure it to provide date and time information to a CUCM server and other devices,

 

Note :- If you want to allow your Router act as NTP server and specify specific interface to provide NTP services then you have to give command “ntp source ”  before “ntp master” otherwise it will give NTP services from 127.0.0.1 .

Cisco Router as DHCP Server

Cisco Router as DHCP Server

Using a Cisco router as a DHCP server is a somewhat common practice in smaller networks.In this example we have two VLANs one for Voice and one for DATA.

DATA VLAN  IP  Nework Range  172.16.1.0  Gateway IP 172.16.1.1  DNS Server  10.31.144.1
Voice VLAN  IP  Nework Range  172.16.2.0  Gateway IP 172.16.2.1  DNS Server  10.31.144.1
TFTP Server for Cisco Phones 172.16.2.1

GK_RTR#configure terminal
GK_RTR(config)#ip dhcp excluded-address 172.16.1.1 172.16.1.9
GK_RTR(config)#ip dhcp excluded-address 172.16.2.1 172.16.2.9
GK_RTR(config)#ip dhcp pool DATA_SCOPE
GK_RTR(dhcp-config)#network 172.16.1.0 255.255.255.0
GK_RTR(dhcp-config)#default-router 172.16.1.1
GK_RTR(dhcp-config)#dns-server 10.31.144.1
GK_RTR(dhcp-config)#exit
GK_RTR(config)#ip dhcp pool VOICE_SCOPE
GK_RTR(dhcp-config)#network 172.16.2.0 255.255.255.0
GK_RTR(dhcp-config)#default-router 172.16.2.1
GK_RTR(dhcp-config)#option 150 ip 172.16.2.1
GK_RTR(dhcp-config)#dns-server 10.31.144.1

If you are using Windows server or some other centralized device for DHCP services. Even Cisco Unified Communications Manager includes DHCP server capabilities. you need to configure ip helper-address <central DHCP server IP address> to your VLAN interface to forward DHCP requests to the central DHCP server for the voice and Data VLANs.
