Welcome to the Cisco Networking Professionals Ask the Expert conversation. This is an opportunity to get an update with Cisco expert Arun Ragunathan on the new Unified Communications product offering for the medium sized businesses. Cisco Unified Communications Manager Business Edition is an easy-to-manage solution that combines voice, video, mobility, and messaging on a single appliance to simplify system administration and reduce hardware and operational expenses. Arun is a product manager for Cisco in the IP Communications group, where he is primarily responsible for Cisco Unified Communications Manager. Arun has worked at Cisco since 2000, holding engineering positions focusing on service provider technologies and enterprise IP phones before moving to product management. Prior to joining Cisco, he worked for MCI and Nortel and has over 10 years of experience in the telecom industry. He has a bachelor's degree in computer science from the National Institute of Technology in India and a master's degree from Keanan-Flagler Business School of the University of North Carolina.

Hi sir

i have the followng questions on CUCM6-BE:

1: regarding licensing issue in CUCM6-BE, is the The Cisco Unified Communications Manager Business Edition base packages for users or for server node and VM ports? or is it a starter license for doing basic config after installation?

2: i did not get the idea behind the add-on user licenses? when to order this add-on lic?

3: doc says that Number of remote sites =

5 (centralized call processing, with Survivable Remote Site Telephony [SRST]), what is the limitation, the number of sites or users per these sites, i mean if i have 10 sites and a total of 400 users is this possible with CUCM6-BE?

4: what about redundancy, is there a possibility somehow to add a backup/subscriber server? if not, isn't it a limitation in CUCM6-BE?

5: what about integration between CUCM6-BE and CME in a case for CME to be backup for CUCM6-BE for failover?

6: are there supported servers other than 7828 ?

sorry for the number of questions

1) CUCM6-BE base package includes 7828 server, software and the first 50 seats. Each seat includes a CUCM user and a VM box. These are permanent licenses.

In addition to the seats, CUCMBE also has 50 device license units pre-populated for initial installation and configuration. DLUs should not be confused with the 50 seats that are included in the base package. The 50 device licenses are not cumulative. They will be removed from the system when purchased device licenses are uploaded on the system.

2) The add-on user licenses are required to build out a specific configuration. For example, if the system needs to support 150 7940 IP phone users, then you need to purchase the base package (which includes 50 seats), then you need to order qty 2 of the 50 seat add-on license to build out the 150 users. You then need to purchase phones and device licenses (4DLUs per 7940 x 150 = 600DLUs).

3) CUCMBE has been tested with 1 central site and 5 remote SRST sites with a total of 500 users. There is no technical limitation on the number of sites. Please check the CUCM 6.0 SRND CUCMBE chapter for better guidance on capacity planning.

4)& 5) The goal for Cisco Unified Communications Manager Business Edition is to offer the reliability medium businesses need in a cost effective manner. CUCMBE has a number of attributes that contribute to the availability of the solution.

a) At the software level, CUCMBE is based on an appliance model. Just as in Unified Communications Manager Appliance, the underlying operating system services are closely managed, hardened and inaccessible. There is no provision for running 3rd party software on the appliance. The appliance environment is tightly controlled and all information exchange is via standard APIs and interfaces. With the likelihood of virus and worm infections from outside sources significantly minimized, the software is inherently stable and secure.

b) At a component level the CUCMBE server has dual cold swap SATA drives that reduce system downtime and greatly improve serviceability in case of a hard drive failure.

C) At the system level, CUCMBE supports SRST at the central/HQ site as well as the remote sites. This is a cost effective solution that has very little administration overhead.

If the application requires the highest level of availability and full call processing feature redundancy in case of the primary system failure, then many customers may choose a Cisco Unified Communications Manager cluster with a redundant server as the optimal solution.

6) No. CUCMBE is currently only supported on MCS7828 appliance.

Hi aragunut.

Can you explain the need for 4 DLU's per 7940? Why four per 7940 and not one? Do all phones need 4 DLU's per phone?


Arun Ragunathan Fri, 08/24/2007 - 12:00
User Badges:

The number of DLUs (Device license units) required for the phones/softclients depends on the phone model. Please refer to Unified Communications Manager ordering guide for the exact number of DLUs required for each phone model.

In Unified Communications Manager 6.0, softclients - Cisco Unified Personal Communicator, Cisco IP Communicator, Cisco Unified Mobile Communicator - require only 1 DLU if they are provisioned as a secondary device or an adjunct device.

My CCNA expired a few years ago, I took the 642-812 and passed it. Will I get credit from passing the exam? And once I am finished the CCNP track, can I go back and take the CCNA.

Hello Arun,

What are the migration options supported on Cisco Unified Communications Manager Business Edition?



Arun Ragunathan Thu, 08/16/2007 - 11:36
User Badges:


CUCMBE is targeted at greenfield customers and is intended for new installations only. Therefore, migration TO CUCMBE FROM Stand-alone Unified Communications Manager or Cisco Unity Connection environment is not supported.

We are currently working on migration FROM CUCMBE TO stand-alone Unified Communications manager environment.

Hardware: We plan to support MCS 7828 HW in a Communications Manager cluster environment in a major version release. We are working on determining the release vehicle now.

Licenses: Device licenses for phones can be migrated to Communications manager today. In addition, migration SKUs will be available in the future to migrate CUCMBE seats to Communications manager.

Data migration will be manual initially. We are trying to get this roadmapped so customers can upgrade CUCMBE to CUCM without having to manually migrate the database.

Hope this answers your question.

Hi, we successfully linked Morocco, but had a problem video and audio from Morocco. They could hear and see us perfectly. The link was through the ADSL link without going through a firewall. What could be the problem.

hi, A small question here.

What kind of issue a customer should expect if running out of sync between database (I guess you can answer all ccm6 release question).

I trying to find out, how can I provide my first level support to identify a syncronization problems between database that will require a "re-sync" or "reset" of database connection.

As the subscriber are now reading there local DB.

In CUCM 6.0, most services read data locally instead of the publisher i.e. read from Communications manager node that phone is registered to. For user facing features like Extension Mobility, Call Forward All etc last update wins.

Hi Arun,

one question regarding security: I know there is a feature in CUCM that allows IP phones to use certificates to register with CCM. Are you supporting this in that business edition too? Do I need those USB tokens for that, i.e. are they mandatory if I want to deploy secure signalization and SecureRTP?

Arun Ragunathan Fri, 08/24/2007 - 12:13
User Badges:

Yes. CUCM Business Edition support the same security capabilities supported on CUCM 6.0.
