Cisco Unified Communications Manager (CUCM) Make It Work

I have created a blog before about the installation of the CUCM https://ccieroot.com/2014/10/24/installation-of-cucm-8-6/ but after that you need to complete couple of steps to make your cucm run like a charm and all of your phone able to call Each Other in the network so lets start

the first step which is optional is to change the server name to an IP Address in case you dnt have a DNS and change the timing of the Server

Go to System – Server – press Find and change the name to an IP

Go to System – Date/Time Group and then Save and Reset

Second thing is the region which is configure by default, you can create a new one but in our case we will leave it as its
From System – Region Information – Region

Third step is the Location which also configure by default which we will use
Go to System – Location info – Location

Now the Biggest thing is the Device Pool which hold all this information together
Go to System – Device Pool and there is one configured by Default and configured with the CUCM Group and Region and the Timing you just need to add the Location to it

Now go to Call Routing – Class Of Control – Partition – Add New

since this blog only about the initial Step after Installation of CUCM i will not explain the partition and CSS but i will show you how to configure it

Save it and now Go to Call Routing – Class Of Control – Calling Search Space and configure the partition under each CSS that belong to
for Ex. Internal CSS only have internal partition which mean he can call people under internal Partition
Local CSS can call Internall Partition and also Local Partition…etc

Now we Configure the phones go to Device – Phone – Add New

Choose the Model of the phone and the protocol

Save and then go to the Left Side to add the Extension go to Line1 Press on it
Choose the Extension you want, in our case we put 7912 and we put it under partition Internal then i give name for the Alerting Name and ASCII Alerting Name and choose a Calling Search Space which we make it a mobile which mean he can call people in internal, local and mobile partition.
and then i configure the name in the field of Display (Caller ID), ASCII Display (Caller ID), Line Text Label and ASCII Line Text Label

Now Configure all your phone the same way with Different Directory Number and Like That all your employee can call each other and like that your CUCM is Ready
The next step is to configure the Gateway and Weather it was H.323 or SIP so you can be able to make an outside call, in our example we will configure an H.323
Go to Device – Gateway – Add New – Choose H.323 Gateway and Press Next it will take you to the page of the Gateway and you need to configure most important is the Device Name which is the IP Address of the Gateway, Device Pool, Location and configure Calling Search Space for Inbound Call when it come to your Port in our Case “Internal”. After you save you have to Reset so the Gateway Will Register to the CUCM

Now We Configure a Route Pattern so Go to Call Routing – Route/Hunt – Route Pattern – Add New
we will configure a route pattern to a mobile Number so you choose the Route Pattern which is 9.05XXXXXXXX, Choose the Route Partition and the Gateway/Route List. Afcors click the Provide Outside Dial Tone and change the Call Classification to Offnet

OMG this is the Longest Blog i ever write but don’t worry
Now this the Last thing to DO is to configure the IOS Gateway
First enable the voice service and allow it to communicate with different protocol

voice service voip
allow-connections h323 to h323
allow-connections h323 to sip
allow-connections sip to h323
allow-connections sip to sip

Then Go Under Each Port and Trunk all of them Under one Trunk Group and also configure that when ever a call come it will go to a specific directory number for example the Reception or the Attendant System … for this example i choose the Reception DN which is 7912

voice-port 0/2/0
trunk-group AYSAR
connection plar opx 7912
!
voice-port 0/2/1
trunk-group AYSAR
connection plar opx 7912

Now Configure the outpound Dial Peer

dial-peer voice 1 pots
trunkgroup AYSAR
description “Mobile Call”
destination-pattern 905……..
forward-digits 10

or

dial-peer voice 1 pots
trunkgroup AYSAR
description “Call Anywhere”
destination-pattern 9T
“This Call the Lazy 9 instead of Configure a dial peer for different Route Pattern (Local, Mobile, international) we just have this one dial peer for all”

and configure an Inbound Dial Peer for incoming Call

dial-peer voice 3000 voip
destination-pattern 791.
session target ipv4:192.168.200.10
dtmf-relay cisco-rtp rtp-nte h245-alphanumeric
codec g711alaw
no vad

Now Try to make a call and it will work and call your company and your phone will work
test it in your environment or lab and if you have any Doubt or didn’t work just ask me

The END
