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.
