If you take a look at the Exchange setup log, it is trying to add firewall rules, and fails, and kills the install. If your windows firewall service is not running, you must start it.  Re run the installation with windows firewall running, and all is fine Smile

Powershell Script to create new user, enable for Exchange, UM and Lync Server

I created this powershell for our internal onboarding process, figured I would share it with the masses.

I think there are a couple good takeways from this script, it remotes into Exchange 2010 and Lync Server 2010 Powershell sessions, so nothing except Powershell 2.0 is required on the client side, which is standard with Windows 7. It also shows how you can simultaneously use Exchange and Lync powershell commands in the same script to get things done.

A couple of disclaimers:

I am in no way advanced at powershell scripting, so nothing fancy here.

This was developed specifically for my internal needs, you will probably have to add/remove variables and requirements.

Script is above, any freedback is appreciated, if you improve on this at all, I would love to see it as well.

Exchange UM Auto Attendant Key Mappings Not Transferring Calls After SP1

After upgrading my Exchange 2010 environment to SP1 we ran into an issue where our Auto Attendant would not transfer calls to our OCS Response Groups and users. If you dialed by name or number, it would transfer, but if a key mapping was set to transfer to an extension, it would fail.

Example:

Primary AA

Key Mapping of 1 set to extension 1000

Extension 1000 is an OCS Response Group Workflow

Key Mapping 4 is set to a separate auto attendant that is speech enabled and intended for use with saying a persons name or extension to reach them.

When a caller pressed the 1 key, the attendant would say “The call could not be transferred”

When pressing 4, and then entering the same extension, 1000, the call would dial properly.

I setup a new AA to run some tests and tried everything imaginable to get this working. No matter what I did, the key mappings would not transfer to an extension, or a full DID of a user off of the auto attendant. All other dial by name or extension functionality worked.

Running traces on the OCS front end and mediation showed no sign of a refer happening, which would appear when the call transfer was attempted.

I finally broke down and opened a PSS case, they had me set a dialing restrictions rule on the Dial Plan and Auto Attendant to allow all numbers.

image

 

Now, normally ,this was only used to dial outbound, so if a user setup dialing rules on their mailbox, or the auto attendant or dial plan had to call a number outside of the organization. I had previously no rules that allowed for any internal number patters, only 10 digit external number patterns.

This is just a normal allow all rule:

image

By setting a rule to allow all dialing and applying it to the dial plan and auto attendant, the issue was resolved.

I will update as soon as I find out if this is a bug, or if it is how it is going to be going forward.

Little Improvements on Exchange 2010 SP1 UM Voicemail

So, I heard about a few improvements with Exchange 2010 SP1 being released. (Full List Here)

One cool thing I just saw, was presence inside the transcription on my voicemail. This may have been there in 2010 RTM and I just didn’t notice it, but this seems new to me.

vm1

As you can see, it detected my name, and put presence next to it, It also added presence to the phone number I left in the voicemail, allowing me to call directly out of the transcription text. This is just another one of the examples as to why the Microsoft Unified Communications package is truly amazing.

The  translation still isn’t perfect, but its getting better and better Smile

Reference: Setting Event Log Levels for Exchange UM

Exchange 2007 and Exchange 2010 allow you to configure different event logging levels for all Exchange services.

I commonly have to enable more detailed Exchange UM logging on UM servers to troubleshoot call flow issues, so here is a quick reference of how to do this.

First off, here is the technet reference to doing this for all services:

http://technet.microsoft.com/en-us/library/bb201670(EXCHG.80).aspx

In Exchange 2007, you must do this through Powershell, Exchange 2010 however is available right in the Exchange MMC.

For Exchange 2007:

Start by opening your Exchange Management Shell

The following powershell commands are required for the Exchange UM services

set-eventloglevel -identity “MSExchange Unified MessagingUMWorkerProcess” -level Expert
set-eventloglevel -identity “MSExchange Unified MessagingUMCore” -level Expert
set-eventloglevel -identity “MSExchange Unified MessagingUMManagement” -level Expert
set-eventloglevel -identity “MSExchange Unified MessagingUMService” -level Expert
set-eventloglevel -identity “MSExchange Unified MessagingUMClientAccess” -level Expert
set-eventloglevel -identity “MSExchange Unified MessagingUMCallData” -level Expert

In Exchange 2010 the same powershell commands will work, however, if you are more comfortable with the UI, you can do it directly in the Exchange MMC.
First open the Exchange Management Console
Expand your On-Premise Organization and select Server Configuration

Select your UM server from the list of available servers, and you will notice on the right hand side, under Actions for that server you will have Manage Diagnostic Logging Properties


Select Manage Diagnostic Logging Properties and you will be prompted with a full list of services on your Exchange server to manage. Expand MSExchange Unified Messaging, for each service you wish to raise the level, select that service, and then select the option for whatever level you wish to enable. Expert is typically a good level to have if dealing with UM.
Once you have configured all of your service levels, choose configure. This will basically execute the Powershell commands listed above and confirm Completion.

Quick Tip: Exchange UM Powershell to list users in a specific dial plan

This is a basic one liner I needed to use today, but I didn’t find it documented that well anywhere.

Situation: Multiple exchange UM dial plans in a company, need to identify users associated with a certain dial plan for whatever reason. In this case it was to migrate them off that dial plan.

Going through the UI to do this would be way too time consuming, of course powershell comes to the rescue.

Using the Get-UMMailbox cmdlet with a basic filter we can identify a group of users with many different attributes in common, in this case we are concerned with UMDialPlan.

Command looks like this:

Get-UMMailbox | where {$_UMDialPlan –eq ‘DialPlanName’}

This will return a list of users in the dial plan you specify. You could of course add more filters in to narrow down the scope.

Alternative to RCC With Cisco and OCS 2007 R2

Often I run into customers that want Remote Call Control with their current phone system as an integration architecture with OCS 2007 R2. Personally I see the benefit to remote call control in LCS, and OCS 2007 R1, but not with the R2 release, and especially with Wave 14 so close. Many times I have had to explain the different scenarios, and why I think a different architecture is a better way to approach this. Today I had to develop this information for a Cisco Call Manager implementation, and wanted to have a reference point, as well as share my thoughts on the subject.

To give a brief background, the customer wanted RCC with Cisco, they currently have an OCS infrastructure in place, and wanted to add the RCC functionality to that environment. In order to do this, they would need to upgrade to Call Manager 7, which is the very first reason to not go any further with the RCC architecture in my opinion. If you are investing in the Microsoft Unified Communications technology stack, there is no reason to dump more money into another UC product along side it.

As a summary, here is a description of what RCC is… Credit goes to this blog post http://blogs.technet.com/jkunert/archive/2008/07/30/voice-scenarios-with-ocs-2007.aspx

This is a description from the R1 release of OCS 2007 but still holds true today.

Remote Call Control (RCC)

Overview

Also this voice scenario was already available in OCS 2007 predecessor Live Communications Server 2005 SP1. The users OC client does not act as a soft phone, does not need an audio or audio/video device connected to the PC and the user is not able to make or receive phone calls by using her/his PC. This is not a VoIP scenario!

User experience

In this scenario, an OCS 2007 user has a PBX or IP PBX phone with an extension (e.g. 1212) standing on her/his desk. In addition to that, Office Communicator (OC) 2007 is installed on the user’s PC.

In the office

On an incoming call the user’s PBX phone rings as well as that she/he receives an incoming call notification (pop-up window) on the bottom right of her/his PC screen, showing the Calling Party Number (Caller ID, phone number of the person who called) and also the caller’s name (if OC could resolve the phone number to a name by matching the phone number against Active Directory or Outlook contacts). The user is able to accept the call by picking up the receiver of the PBX/IP PBX phone or by clicking on the pop-up window for the incoming call on her/his PC. In both cases, media (voice stream) will stay on the PBX/IP PBX and there will be no VoIP connection to OC! The user does not need an audio device for telephony connected to her/his PC.

At home/on the internet

If the user receives an incoming call to her/his office number while being connected to the company’s IT environment over the internet (e.g. at home), the users PBX/IP PBX phone will ring in the office (what she/he most likely will not be able to hear J) as well as that she/he can see the pop-up window generated by OC on her/his PC. Accepting the call by clicking on the pop-up window will result in this scenario that the phone in the office will activate the speaker phone, but the user is not able to use her/his PC to talk to the caller. No VoIP connection through the internet is established! (However, the user can redirect an incoming call to her/his mobile phone and can pick up the call this way while working remotely.)

How it works in a nutshell

A CSTA Gateway (GW) needs to be installed between OCS 2007 and the PBX/IP PBX. Some PBX/IP PBX systems come with a CSTA interface natively so there is no need for an additional GW. Between OCS and the PBX/IP PBX call control commands will be sent, packed into a SIP INFO message that uses a long-lasting SIP dialog between OCS and the CSTA GW. The CSTA GW converts these call control messages into a format that the PBX/IP PBX understands. A CSTA GW is not a media GW so voice cannot be converted by a CSTA GW from a TDM (Time Division Multiplexing) or PSTN protocol to VoIP! OC can only control the functions of the PBX/IP PBX phone.

 

With a Cisco integration, we would actually be able to do direct sip as long as the following software requirements are met on the Cisco side:

  • Cisco Unified Communications Manager Release 7.0(2)
  • Cisco Unified Presence Release 7.0(3) with E.164 patch for RCC

One of the key features of the Microsoft OCS Platform is the ability to have not only integrated IM and Voice calling, but also conferencing, all within the same application, and all available through a single click. Any communication can be escalated to a conference by inviting PSTN or VOIP participants at any time. When you introduce the remote call control scenario this is no longer available. A Key thing to point out is that a user in this scenario cannot make or receive calls using communicator, they still must use the Cisco phone in all scenarios, which virtually eliminates the remote worker benefits of OCS.  Below is the list of other limitations taken from the Cisco Documentation on this configuration:

Features Not Supported

· Microsoft OC logon from two locations

· Call Forwarding

· Location Based

· Phone Settings

· Conferencing through remote call control

Limitations

· Conferencing: OCS 2007 R2 does not support call conferencing through remote call control. Conferencing is available in IP Phone

only or OC only call scenarios.

· Call forward setting on IP phone: Call forward setting made on the Cisco IP phone (desktop), using its soft key button or the Cisco

UCM phone configuration page, is not reflected by the Microsoft OC GUI. As of Microsoft OCS 2007 release, this feature is not

supported. The Microsoft OC can override any call forward setting manually configured on the IP Phone and vice versa.

· Call Forward Setting from OC: Call forward setting from the OC through remote call control (RCC) fails on the IP Phone when the IP

Phone is initially configured with an E.164 DN. If the IP Phone is reconfigured to a non-E.164 DN then back to the E.164 DN, the

call forward setting from OC through RCC will work. This is a known issue on Cisco UCM 7.0(2) and has been documented in

CDETS CSCsy62620 to be fixed in a future release.

· Do Not Disturb (DND): DND is an unsupported feature with respect to CUP integration. Thus, any OC client with DND feature

enabled, will still have any received calls routed to its controlled IP Phone.

· Multiple Point of Presence (MPOP): As of the CUP release 6.0(1), the MPOP feature where a Microsoft OC user is logged in from

more than one location is not supported by CUP. Support for this feature affects other interoperability features between the Cisco

CUP and the Microsoft OCS. The affected features include basic placement and teardown of calls and locations-based call forwarding.

These features are inherent to MPOP and without support for this feature, the user experiences loss of device and call control when

logged in multiple locations.

· Transport Layer Security (TLS) connection between CUP and OCS: this feature was not tested in this release.

As you can see, you quickly start to lose a lot of the functionality of OCS. I will stress that the above is strictly related to Cisco, and may not be completely accurate for other RCC Scenarios.

The other option, and most optimal solution in my opinion can be most closely referred to as a standard Enterprise Voice Scenario. Really, it is the cheap way of doing remote call control.

Last year I had multiple voice deployments which had to provide interop between OCS and the existing PBX, mostly Avaya and Cisco systems. A key requirement of all of these deployments was the ability to pilot OCS functionality but also have access to their old phone for use. The architecture we used to provide this can be seen below. We had to make a connection between the OCS environment and the PBX, whether it was a Sip trunk to cisco, or a PRI connection via media gateway to the other systems. From there we have two options for routing incoming/outbound calls for OCS enabled users.

The first scenario is where the PBX controls the call routing. All PRIs, or SIP trunks come directly into the PBX, from there you have routing rules to route certain numbers over a trunk to OCS. This can be accomplished by setting routing rules at the PBX level, or simply forwarding your PBX Desk phone to your OCS extension, which will route it over to the OCS Trunk. It is important to note that in both scenarios you are configured for different extension on the PBX and OCS. Where your “real” extension goes depends on how you wish to route/forward calls. Regardless, any DID numbers, or existing extensions are still usable, it’s just a matter of getting the call there. In this scenario for example, you may have “fake extension” in OCS, and when your existing extension is rung, your cisco phone forwards the call to your OCS extension, in the PBX this new block of OCS extensions is configured explicitly to route over that new trunk, this is the simplest way to make this connection happen with the least amount of changes on the existing PBX environment.

The other scenario lets OCS control the call routing. In this scenario all PSTN calls destined for OCS Enabled users go directly to OCS. This can be more difficult to implement at first, but once it is in place, it provides a very smooth transition. This can be accomplished from a direct SIP trunking connection to an OCS mediation server, or a PRI/POTS connection from a provider, into a media gateway, which then sends the calls on to the OCS mediation server. It is possible to move all incoming PRI connections to a media gateway, which would then control all calls. From there that media gateway can send to the PBX or OCS. In the Cisco world, this could actually be a 2800 or 3800 series ISR. To some people this is a bit scary to hear at first, but really, your current PRI lines come into some sort of gateway device as it is, this would provide the same functionality. The gateways used are by companies like Dialogic and NET with great experience doing this for years for traditional PBX systems, so it is more than reliable. From here, there is also a trunk setup to the PBX to route extension dialing, as well as for simultaneously ringing the legacy PBX phone.  In both scenarios the voicemail can be sent to exchange unified messaging or back to the PBX voicemail system. When OCS has no answer, it can make this choice. The PBX will be smart enough when the call comes back and is tagged with no answer, to send it directly to voicemail instead of creating an endless ringing loop.

In scenario two, if the media gateway takes all PSTN calls in, it will have some basic routes on it. Routes that control sending OCS enabled users to the mediation server, and then a default route which will send everything to cisco. Basically, if you had 5 users enabled for OCS. You would have a rule on the gateway that had 1000-1005 with a destination of the mediation server. The second route would be * (any) with a destination of the PBX. This takes the load of modifying PBX configuration.

In this specific scenario, the media gateway could be a dialogic/NET device, or simply the PRI interface on the Cisco ISR.

It is important to note that with both of these scenarios you have full functionality of both systems at any given time. You can use your cisco phone to make and receive calls, or your OC client to make and receive calls. You can also take advantage of all conferencing, and other advanced functionality that OCS has to offer like remote access.

CiscoEVScenario

There may be some things that need clearing up in this, and I am open to some feedback, but this is really what I have been going off as a reference point for myself with these deployments. Another important factor is the retirement of Dual Forking and RCC in Wave 14 of OCS set to be released this year, existing OCS 2007 R2 implementations will be supported, however new deployments will not. This has made some companies forget about RCC implementations all together.

Configuring Custom Exchange UM Auto Attendant Prompts (Part 1)

In my previous post I outlined how to record Custom UM Auto Attendant Prompts in the correct format for Exchange 2007 UM. This post will outline how to import these and apply them to UM Auto Attendants, Part two will cover some From the Field Experiences the WinXnet team has developed to outline how we suggest utilizing the auto attendants in customer and internal deployments.

First step once you have these recorded and have the files on your Exchange UM server is to import them into the Dial Plan directory so they can be assigned to the auto attendants. The .WAV files themselves can be stored on any drive local to the UM server, however there is a power shell command that must be entered to publish the file to the UM Prompt Publishing Point. The UM Prompt publishing point is a shared folder that is created on the first UM server installed in the exchange organization; any additional UM servers in the environment check periodically and update their Prompt Cache based on the files in this folder.

See below for the power shell command and syntax that goes along with this:

Copy-UMCustomPrompt –Path -UMDialPlan

The string entered to generate the logs below in my environment was: Copy-UMCustomPrompt –Path E:winxgreetingnew.wav –UMDialPlan WXUM

This command will simply return a fresh power shell line and the cache update process will be started. To confirm the files have been updated in the UM Cache you want to look for these Informational Messages in the Event Viewer.

This first message confirms that the custom prompt files were updated:

This second message confirms that the cache update process has been completed by the server, this happens every 5 minutes on the UM Server by default:

Now that the files are in the cache for UM, we can assign to an auto attendant. To do this select your Auto Attendant properties and choose the Greetings tab, see below:

After a few minutes of replication for changes this greeting should now take effect when you call the Auto Attendant. You will notice the spacer settings of this auto attendant which I am going to follow up on from the WinXnet UC team experiences around using the UM Auto Attendants.
