Hi Arun,

   For unified messaging, I would consider the following

1. Exchange on-premise (2003, 2007 or 2010) or cloud (Office 365)

2. What UM features you're looking for i.e. Single Inbox, SpeechView, TTS, Access to Exchange Calendar etc. For more details, I suggest the following -

Introduction to Unified Messaging in Cisco Unity Connection 9x

http://www.cisco.com/en/US/docs/voice_ip_comm/connection/9x/unified_messaging/guide/9xcucumg010.html

3. UM accounts that are created in Exchange with role of ApplicationImpersonation. For more details on Unity Connection Single Inbox and Exchange 2010 performance characteristics, I recommend the following document

Cisco Unity Connection Single Inbox with Microsoft Exchange 2010

http://www.cisco.com/en/US/prod/collateral/voicesw/ps6789/ps5745/ps6509/solution_overview_c22-713352.html

4. UM Service to be created on Unity Connection. This can be used for granting UM feature access to users.

For example, you might configure one unified messaging service that enables text to speech (TTS), another that enables access to Exchange calendars and contacts, and a third that enables single inbox. With this design, if you want a user to have access to all three features, you would create three unified messaging accounts for the user, one for each of the three unified messaging services.

5. Number of users with UM feature is the same as a voice messaging deployment, however the following consideration applies "Allowing Connection or Exchange mailboxes larger than 2 GB can affect Connection and Exchange performance."

6. Populating SMTP Proxy address field in unity connection for each user with UM access. This is the user's exchange email address or use Viewmail for Outlook (VMO) as it addresses messages to Unity Connection only.

7. Firewall b/w Unity Connection & MS Exchange. For more on ports used by Unity Connection, refer to

IP Communications Required by Cisco Unity Connection 9.x

http://www.cisco.com/en/US/docs/voice_ip_comm/connection/9x/security/guide/9xcucsec010.html

8. Bandwidth Requirements. For that I recommend going through the following document

Requirements for Using Unified Messaging Features

http://www.cisco.com/en/US/docs/voice_ip_comm/connection/9x/requirements/9xcucsysreqs.html#wp515351

9. Round Trip Latency should be less than 250 ms. Sync threads required for mailbox sync or else users may experience delays. The default is 4 and the max is 64 (can be changed by a CLI command). For more details on latency and calculating connections needed, refer to Latency section in the design guide located here -

http://www.cisco.com/en/US/docs/voice_ip_comm/connection/9x/design/guide/9xcucdg032.html#wp1132131

10. Whether or not secure voicemails are required by user with UM access.

11. Mailbox quotas & messag aging in connection. As mentioned earlier having mailbox size of 2GB or more can affect Exchange & Connection performance. So having mailbox quotas & message aging policy can help in improved performance. Preferrably have the same quota at both ends.

From a deployment perspective, you need to consider the following

1. UM accounts & services to be used for UM features

2. Populating SMTP Proxy address. One way of doing this is to enable LDAP sync and creating a user template with Generate SMTP Proxy Address with corporate email address checkbox checked. If you're adding users via BAT, the field is CreateSmtpProxyFromCorp. In case you're updating existing users the field is SmtpProxyAddresses. For details, I recommend the following document -

Using the Cisco Unity Connection 9.x Bulk Administration Tool

http://www.cisco.com/en/US/docs/voice_ip_comm/connection/9x/user_mac/guide/9xcucmacappa.html

3. For more details on configuring UM for Unity Connection, I recommend the following guide

Hi Aashish,

What exactly is the command to monitor UCxN working in HA mode , the way we do in Cisco Call Manager [utils d breplication runtimestate]?

Hi Aman,

The cli command show cuc cluster status is one possible way. The  second group of information displayed by the command pertains to database replication. If database replication is running, the State field for both the pub and sub server should be Active and the Status field should show Connected for the other server. Here's an example of the command output for both a Pub and Sub where database replication is working properly:

Command run on the Pub:

admin:show cuc cluster status

Server Name   Member ID  Server State  Internal State  Reason

------------  ---------  ------------  --------------  ------

sea-vm-ks-16  0          Primary       Pri Active      Normal

sea-vm-ks-17  1          Secondary     Sec Active      Normal

SERVER                 ID STATE    STATUS     QUEUE  CONNECTION CHANGED

-----------------------------------------------------------------------

g_ciscounity_pub      100 Active   Local           0

g_ciscounity_sub1     101 Active   Connected       0 Nov 22 10:55:57

###########

################

Command run on the Sub:

admin:show cuc cluster status

Server Name   Member ID  Server State  Internal State  Reason

------------  ---------  ------------  --------------  ------

sea-vm-ks-16  0          Primary       Pri Active      Normal

sea-vm-ks-17  1          Secondary     Sec Active      Normal

SERVER                 ID STATE    STATUS     QUEUE  CONNECTION CHANGED

-----------------------------------------------------------------------

g_ciscounity_pub      100 Active   Connected       0 Nov 22 10:55:57

g_ciscounity_sub1     101 Active   Local           0

###########

###################

Here's an example of running the command on the Pub where database replication with the Sub is disconnected:


admin:show cuc cluster status

Server Name   Member ID  Server State  Internal State  Reason

------------  ---------  ------------  --------------  ------

sea-vm-ks-16  0          Primary       Pri Active      Normal

sea-vm-ks-17  1          Secondary     Sec Active      Normal

SERVER                 ID STATE    STATUS     QUEUE  CONNECTION CHANGED

-----------------------------------------------------------------------

g_ciscounity_pub      100 Active   Local           0

g_ciscounity_sub1     101 Active   Disconnect      0 Nov 22 17:15:33

Here's an example of running the command on the Pub where database replication has been torn down and is not running:


admin:show cuc cluster status

Server Name   Member ID  Server State  Internal State  Reason

------------  ---------  ------------  --------------  ------

sea-vm-ks-16  0          Primary       Pri Active      Normal

sea-vm-ks-17  1          Secondary     Sec Active      Normal

Database replication is not active

Hi Aashish,

My requirement is to receive  the incoming fax from outside to my Email. Is there any way to achieve this without using third party server like RightFAX and configure FAX option if available in UCxN ?

Please advice.

regds,

Ask the Expert: Designing, Configuring & Monitoring of Cisco Uni

Hi Aman,

    Currently fax integration in Cisco Unity Connection requires a Fax Server. The following 3rd party fax servers are supported

OpenText Fax Server, RightFax Edition, versions 9.x and later. For more information, see the www.opentext.com

Sagemcom Xmedius Fax SP version 6.5.5. For more information, see the www.sagemcom.com.

Cisco Fax Server, version 9.x


Note Cisco will no longer be selling Cisco Fax Server version 9.x after May 2011; however, support for Cisco Fax Server will continue until May 2014. For detailed information on end-of-sale and end-of life dates for the Cisco Fax Server, see the information at http://www.cisco.com/en/US/prod/collateral/voicesw/ps6789/ps5745/ps2237/end_of_life_notice_c51-630608.html.

Hi Aashish,

How are the resources planned on the Cisco Unity for an enterprise having 400 users which would later scale upto 1000 users with basic Voice mail features.

Ask the Expert: Designing, Configuring & Monitoring of Cisco Uni

Hi Dilip,

   I assume you're referring to Cisco Unity Connection here as Cisco Unity went end of sale in Jan 2012. Considering Unity Connection 9.1.1, a 1000 user system would need the following

vCPU = 1 (2.13 GHz reserved)

vDisk = 1 x 160 (file system aligned at 64KB blocks)

vRAM = 4 GB

You also get the following with this template

Approximate message storage, G-711 codec, minutes = 72,944

Voice Ports per server = 24

Users = 1000

For more details, I recommend the following interesting documents

Hi Ashish,

This discussion post is really interesting and helpful.. I have a basi question here.. Since i came into Designing work newly.

As per the Cisco Recommendation 24 ports for Standalone Cluster and 48 Ports for Active/Active Cluster config. May I know how these 24 ports are mapping to 1000 users?

Regards,

Bala

Ask the Expert: Designing, Configuring & Monitoring of Cisco Uni

Hi Bala,

   The typical port to user ratio is 1:40, with that in mind, we will require 24 ports as the license is available in increment of 2 and hence 25 ports is not possible.

Regards,

Aashish

Re: Ask the Expert: Designing, Configuring & Monitoring of Cisco

Hi Aashish,

Yes, It was there in my mind befiore i ask the question, But if we apply that ratio for 10,000 or 20,000 users, Output is coming in different figures from Cisco Recommendation.

Example:

For 10,000 users

As per 1:40 ratio calculation = 0.025 * 10000 = 250 Ports

As per Cisco Recommendation = 150 Ports

For 20,000 users

As per 1:40 ratio calculation = 0.025 * 20000 = 500

As per Cisco Recommendation = 250 Ports

It would be great if you clear my confusion here, Thanks again..

Hi Bala,

   That is a good question and I never paid attention to it. Typically we just deploy as is, however I'm researching further to get clarification on this point i.e. to find out the factors contributing to the port calculation and I'll keep you posted on it.

Hi Aashish, I have a recurring issue with Unity Connection remote port status monitor application.  When I attempt to use this I have already enabled "port status monitor output" and added my IP address to the list of allowed IP hosts in the Conversation section of Advanced settings.

I am using rPSM 2.0.0.16 and  UnityConnection 8.6.1 or 8.6.2.  I've noticed that I will get the "Connection  refused by remote server - make sure the IP address of the client  machine you're running remote port status monitor on is included in the  list on the Connection server that allows for remote connections.  See  help for more details." error message.

If  I am patient enough, and keep trying it will eventually let me in after 5 or 10 minutes.  Is  there a service I can restart to speed this conversation up or do I just  need to wait for the timeout value before the allowed list is  refreshed?

thanks,

Kasey

     Hi Kasey,

   The issue you've mentioned is quite strange. I would try the following

1. Update to the latest version available here -

http://www.ciscounitytools.com/Applications/CxN/PortStatusMonitorCUC7x/PortStatusMonitorCUC7x.html

2. Double check unity connection configuration for RPSM i.e.

    - 'Enable Remote Port Status Monitor Output' Checked

    - IP Addressess Allowed to Connect For Port Status Monitor Output (comma-separated) populated with client IP      Address.

3. If the issue persists, restart Connection Database Proxy & Connection Realtime Monitoring API's

4. If the issue is still persistant, we'll have to grab packet captures to see what is happening on the wire.

Aashish
