where is BLF in version 4.0?

Hi Rob,

Just to add a note to the good info from Arvind. There are no BLF settings in CCM 4.0. Have you tried this setting for each Shared Line appearance on the 7914;

Line Settings for this Device

Ring Setting (Phone Idle) Flash Only

Ring Setting (Phone Active) Flash Only

This way the Extension that the person with the 7914 is monitoring will only Flash and not Ring on the 7914. Usually a very helpful thing for the Admin person.

Hope this helps!

Rob

yea, I have tried that, but the call shows on the display of the receptionist 7960 phone though. I just want the button beside the extension to flash and change color as the action is different.

hmm. I have another CM 4.0. that location does not have DID and the 7914 on there shows the extension and changes color as needed, but that doesnt ring on the receptionist phone. It just shows on the 7914 side car.

Rob,

Will an upgrade from CCM 4 to CCM 5 allow a BLF scenario to be used or do you have to have the Presence server?

Regards,

Kerrie

BLF works well on CCM5 without presence server.

Thank you for replying, does DSS work as well? I should have asked the question for both BLF/DSS.

Hi Kerrie,

Sorry for the delay :) Yes, both DSS and BLF are supported natively.

Unified CM Presence Guidelines

Unified CM enables the system administrator to configure and control user presence capabilities from within Unified CM Administration.The Cisco Unified Presence Server is used for Instant Messaging and Presence Leveraging Extensions (SIMPLE) to provide a common demarcation and point for integrating all SIP or SIMPLE applications into the Cisco Unified Communications System.

Unified CM Speed Dial Presence

Unified CM supports the ability for a speed dial to have presence capabilities via a busy lamp field (BLF) speed dial. BLF speed dials work as both a speed dial and a presence indicator. However, only the system administrator can configure a BLF speed dial; a system user is not allowed to configure a BLF speed dial.

The administrator must configure the BLF speed dial with a target directory number that is resolvable to a directory number within the Unified CM cluster or a SIP trunk destination. BLF SIP line-side endpoints can also be configured with a SIP URI for the BLF speed dial, but SCCP line-side endpoints cannot be configured with a SIP URI for BLF speed dial. The BLF speed dial indication is a line-level indication and not a device-level indication.

The following Cisco Unified IP Phones support BLF speed dial for SCCP:

Cisco Unified IP Phone 7914G

Cisco Unified IP Phone 7940G

Cisco Unified IP Phone 7960G

Cisco Unified IP Phones 7941G and 7941G-GE

Cisco Unified IP Phones 7961G and 7961G-GE

Cisco Unified IP Phones 7970G and 7971G-GE

The following Cisco Unified IP Phones support BLF speed dial for SIP:

Cisco Unified IP Phones 7941G and 7941G-GE

Cisco Unified IP Phones 7961G and 7961G-GE

Cisco Unified IP Phones 7970G and 7971G-GE

The Cisco Unified IP Phones 7905, 7906, 7911, and 7912 do not support BLF speed dial.

Thanks Rob, I had to make sure I don't need a Presence Server with CCM5 to get the BLF working.

What do you mean by DSS?

Hi Anton,

Sorry about that, I shouldn't really use that name here as it is really associated with CME. Old habits die hard!

DSS (Direct Station Select) Service

In Cisco Unified CME 4.0(2) and later versions, the DSS (Direct Station Select) Service feature allows the phone user to press a single speed-dial line button to transfer an incoming call when the call is in the connected state. This feature is supported on all phones on which monitor line buttons for speed dial or speed-dial line buttons are configured.

When the DSS service is enabled, the system automatically generates a simulated transfer key event when needed, eliminating the requirement for the phone user to press the Transfer button.

In this case, for CCM, the terminology really should be "BLF speed dial" :)

Hope this helps!

Rob
