Cisco Call Manager Express with Exchange 2007 Unified Messaging Part 2

Posted on September 27th, 2008 in CME, Call Manager, Cisco, Cisco CallManager, Microsoft, Microsoft Exchange, VoIP by Mohammed

As promised, here’s Part II. The worked example is from a live environment so there may be some inconsistencies between the configs in the earlier article and this one. I’m working on reconciling both!
From the Exchange Management console, go to “Organization Configuration” select the Unified Messaging object.

The following tabs are available:

  • UM Dial Plans
  • UM IP Gateways
  • UM Mailbox Policies
  • UM Auto Attendants

In this worked example, we’re after a simple voicemail solution and so we’ll skip the configuration of UM Auto Attendants.

Summary of Steps

  1. Create UM Dial Plan
  2. Check associated default UM Mailbox Policy & adjust as necessary.
  3. Add new UM IP Gateway
    1. Associate previously created Dial Plan (creates default hunt-group)
  4. Assign Dial Plan to Server
  5. Configure Exchange mailboxes for UM

Night-Service … it’s the non-office hours stupid!

night-service weekday 08:00 17:00

Q. What does it do?

A. Switches on night-service, e.g. divert to voicemail during office hours :)

What it should say:

night-service weekday 17:01 07:29

This is what happens when you’re doing stuff at 3 am in the morning during a marathon config. session. Same night, my colleague managed to allocate 65 gigs of RAM to a VM in ESX Server saying “I thought we had more than 6 Gigs available”!

Note to myself: Add the following to troubleshooting flowchart:

Has engineer had enough sleep?!

Cisco VoIP Video Series: Configuring Cisco Unity Express

Posted on September 18th, 2008 in CME, Cisco, Cisco CallManager, Cisco Unity, Cisco Unity Express by Mohammed

I’ve been playing around with Camtasia for a while and have started using it for visual “documentation” purposes. Making sense of Screenshots is quite long-winded, especially when you haven’t annotated them at the time you took them.

I’m going to start my Cisco CallManager series with CUE configuration, mainly because I’ve just bought the module.

Cisco Unity Express (or whatever they call it now) is a module that slots into the carrier slot of a router eg 2600/2800 series. I’ve got in in my 2811. It’s basically a small computer running Linux with a 2.5″ hard disk. I paid around $1000 for mine off Ebay and I was quite disappointed by the size of the thing, it’s tiny :), especially after having to pay import duty!. In this 2-part video, I go through most of what’s required for CUE configuration for the CCIE Voice Lab scenarios I’ve come across. The videos are unedited, so expect unnecessary pauses while I’m thinking etc :) Enjoy!

In this part, most configuration is done in the IOS and CUE O/S

In part 2, I’ve continued configuring the GUI

Looking forward to comments.

Hidden Network Adapters & P2V Converstion

Posted on August 3rd, 2008 in Cisco, Microsoft by Mohammed

I came across this issue when converting an Acronis .tib file to a vmware image using Vmware Convertor. I had issues assigning an ip address as it was apparently already assigned to an hidden adapter?! Well, I found out later that the hidden NICs were left over from the physical machine. Here’s how to un-hide them.

IPCC Express IP Address Changes

You’ll probably gather that changing the IP address in Windows doesn’t automatically propagate to the dependent CRS services!

On “Knowledge Sharing”

Posted on July 20th, 2008 in Uncategorized by Mohammed

Dilbert Knowledge

From “Network Warrior” ISBN 0-596-10151-1

“Sharing knowledge is good; withholding it is bad. People seem to think that they should never share what they know because they’ll lose their jobs. This couldn’t be farther from the truth, unless you’re working for a despot. Teams work
better together, and respect is formed when information is shared. Troubleshooting is more efficient when more than one person knows how something works. Think about who you admire in the computer industry. Chances are you admire those people because they’ve taught you something.”

Oh, about the book - buy it, it’s good! I’ll be doing a review of it soon once I’ve gone through it properly.

A Great CallManager Configuration Resource

So typical of bloggers, they suddenly disappear off the radar! But here’s a great resource to kick-start some more activity.

Based on a case study, these configuration examples are a great way to fill any gaps in knowledge. Click on any graphic and you’re taken to the configuration steps for that device.
