Paging configuration in Call Manager Express

Just came across a requirement from a customer for implementing paging in Cisco Call Manager Express       ( CME )

The config is pretty much simple .

First  you need to define a ephone-dn for the paging and need to define a multicast ip address for paging.
The config will look like this  :

ephone-dn  5
 description Paging
 number 1001
 paging ip 239.0.1.20 port 2000

one u have configured the ephone-dn.
Apply the ephone-dn to the ephone you have configured in CME .

ephone  1
  paging-dn 5
!  
!
ephone  2
  paging-dn 5

Once the user dial 1001 from any phone .It will establish a one side audio to all the phone for paging.

Changing Bearer Capability in ISDN gateway

Many time it had happend with me that i get a bearer capability mismatch between my gateway and service provider switch due to which the call didn/t mature
and during troubleshooting you run the command " debug isdn q931 " in the router and get a error similar to "Invalid information element contents and Incompatible destination"

This signifies that the bearer capability of the service provider switch and the voice gateway didn't match.

In order to resolve this kind of issue there is a option  in the IOS gateway that you can  overwrite the bearer capability  using the IOS command in the voice-port config mode...

The command for this is

config−voiceport)#bearer−cap ?

This will give you option to overwrite the capability set....

Abbreviated dialing

Abbreviated dialing is similiar to speed dial and can be invoked by pressing the " abbvr " softkey.

The abbreviated dialing can be configued from the ccm end user page and selecting the device and configure the speed dial.

for example lets the 6th abbdial number you configured in end user page is 12345678.

Now in phone press a new call , enter 6 and press the "abbvr" softkey .

once pressed it will change the number to the number (12345678) you configured in end user page ..

Sending Mwi in different extension other then voice mail

During my various implementation project i came across a common requirement which is having a common voice mail box to a group of users
and the requirement is that they get a visual mwi indication to there extension when a call came to the common voice mailbox.

How to acheive this ????


Now to start with lets say your common voice mail box number is 1000 and you want the indication on the extension 2001,2002  etc

for enabling this go the the common mail box user setting in unity and navigate to Edit > Message waiting indicator

Add a new message waiting indicator  and mention the extension 2001 and 2002 etc



This will acheive the message indication when a  message got left in the common voice mail box ..

Changing Phone background in Cisco IP Phone

This is a very common requirement to customize the background image of phone for various deployment and is very commond practice across organization for branding purpose.

Here i am going to discuss the steps that you need to change the background image  for cisco phone.

Below are the few point that you need to keep in mind to acheive the result:

1. Keep with you the List.xml file remember the name of the file is case senstive

The xml file should contain the below text
 <CiscoIPPhoneImageList>
<ImageItem Image="TFTP:Desktops/320x212x16/TN-Image.png"
URL="TFTP:Desktops/320x212x16/Image.png"/>
</CiscoIPPhoneImageList>

2. Keep with you the image file that you want to upload  ,Actual Image size should be 320 x 212 pixels and the thumbnail image size should be 80x53 pixels

e.g Name the original image as  Image.png and the thumbnail as TN-Image.png

Now upload all the file  files to the TFTP file management by navigating to Operating Systme Administration > TFTP file management and upload the file , mention the directory for the file which will be specific to phone model for e.g Cisco 7941-61 uses /Desktops/320x196x4 as a directory.

Cisco IPMA -Manager Assistant feature

Cisco Manager assistant feature with proxy line support is a service in CUCM that intercept the manager call and send it to the assistant, So that the assistant answer the call. The manager can control this behaviour from his phone and softkey and enable or disable the divert .

There are a few steps to acheive this configuration which i am going to discuss here one by one.

1. First  Create  a Partition for the Manager Phone name it as PT-Manager
2. Create a partition for all Phone name in PT_All
3. Create two CSS one for all Phone name it CSS_All  -- PT_All, CSS_IPMA -- PT_All + PT_Manager


4. Create a CTI Route Point and assign it a DN 10000X (Remember the DN should be a Full number or mask that matches with the manager DN in our case manager DN is 10001

The CSS of the CTI RP should be CSS_IPMA that has access  to the Manager Phone and Agent Phone

5. Create a IPMA service from the Phone Service options

6. Go to service parameter and choose IPMA and define the below mentioned paramater




7. Assign the manager Phone the Softkey template for manager and subscribe to IPMA services and in the Assistant Phone associate the Softkey template for assistant

8. Go to Enduser and choose the manager user and associate the Manager Phone and assign the CTI role to the end user
9. Go to the enduser page and associate the assistant phone to the assistant User  and assign the CTI role 
10.In the Manager user from the related link choose the manager configuration and define the mapping for asistant phone  with the Manager phone


many time after the configuration you may need to restart the below services for troubleshooting

1. Cisco TFTP server
