Time Synchronization between Windows Domain controller and domain clients

net time \\1.2.3.4 /set /yes

If you are in a Citrix XenDesktop 4 environment, you need the time sync otherwise the hosted VM can't register to the DDC

Mobile Supervisor on iPhone

My environment:  Mobile Supervisor for iPhone 2.0.2.0, UCCX 8.0

Just one quick note, if you want to use the Mobile Supervisor client on iPhone, you need to specify the IP address and port number in iPhone Settings > Supervisor.  The port number is 12028.

Using CAD integrated browser for SocialMiner

My environment: UCCX 8.0.2 on Windows 7, SocialMiner 8.5

Just wanna share some experience with you that how to get it works. The problem I had is, when I used the Windows 7 IE 8 to browse the SocialMiner page, it works fine. However when I used the CAD integrated browser to browse SocialMiner page, it shows the error "This version of Internet Explorer is not supported. Internet Explorer 8 or later is required"

When I visit the page: http://www.quirksmode.org/js/detect.html, it detected that the integrated browser running is IE 7 instead of IE 8. This is because for compatibility purposes, the WebBrowser control is running IE 7 standard mode instead of IE 8:

http://blogs.msdn.com/b/ie/archive/2009/03/10/more-ie8-extensibility-improvements.aspx

The changes I have made is, based on the above link, under FEATURE_BROWSER_EMULATION, add a new dword named "agent.exe", with the value decimal 8888 to force IE 8 standard mode. For Windows 7 64-bit, the path is different:

HKEY_LOCAL_MACHINE\Software\Wow6432Node\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION

After making the changes, restart the computer then you will see SocialMiner page shown in the CAD integrated browser!

Please be aware this is for lab settings only, changing the above values may have support issue!

CME + CUE integration

My environment:  CME and CUE 7.0


CUE can be configured to integrate with CME and UCM, in this post I will give you an example on how to create integration between CME and CUE.  Make sure you have the correct license, as integrating with CME and UCM requires different licenses.


Sample Configuration for CME+CUE integration

On CME side

interface in1/0

     ip unnumbered gi0/0.502

     service-module ip address 1.2.3.253 255.255.255.0

     service-module ip default-gateway 1.2.3.254

ip route 1.2.3.253 255.255.255.255 in1/0

dial-peer voice 4050 voip

     destination-pattern 4050

     session protocol sipv2

     session target ipv4:1.2.3.253

     dtmf-relay sip-notify

     codec g711ulaw

     no vad

telephony-service

     voicemail 4050

ephone-dn 11

     call-forward busy 4050

     call-forward noan 4050 time 10

ephone 14

     number 8000....

     mwi on

ephone 15

     number 8001....

     mwi off

On CUE side

ccn application voicemail

     max session 4

ccn trigger sip phonenumber 4050

     application voicemail

     enabled

     maxsession 4

Done!  You can try to either call in the voicemail pilot or press the envelop button see if you can hear the prompt.  Next step is to create the user in CUE then you can leave a message.

Some other commands that you will find it useful during the integration.

Factory Reset CUE

On CUE

offline

restore factory default

Other commands

CME:     service-module in1/0 session

CUE:     show software license

CUE:     software install clean url ftp://1.2.3.4/xxx.pkg

cBarge and Privacy on CME

My environment:  CME 7.0

Note
- When privacy on hold is enabled globally, when the phone enabled privacy (the privacy button is on), you can't see the phone is on hold on the shared line.  If you disable the privacy on hold, then even the privacy button is on, you can see the phone is on hold.

Shared Line and Overlay DNs on CME

When you have started to work on CME, you will find that there are several types of shared DNs that is possible which allow great flexibility to fit your customer needs.  In this post I will lay out 3 scenarios with configuration and expected result, so that you can get better understanding on how it works.

My environment:  CME 7.0

Scenario 1 - one ephone DN for multiple ephone

ephone-dn 1 dual-line
     number 4001

ephone 1
     button 1:1

ephone 2
     button 1:1

- When receive a call to 4001, both ephone 1 and 2 will ring. 
- ephone 1 answers call, ephone 2 in remote in use state
- another incoming call will go to ephone 1 second channel
- yet another incoming call - will busy out, the call will not roll over to ephone 2
- ephone 2 can't use that line for outgoing call

Scenario 2 - 2 ephone-dn with same number with preference

ephone-dn 1 dual-line
     number 4001
     preference 1

ephone-dn 2 dual-line
     number 4001
     no huntstop
     huntstop channel

ephone 1
     button 1:1

ephone 2
     button 1:2

- ephone-dn 2 is preferred to ring when somebody calls 4001
- no huntstop on ephone-dn means it continues to search for another ephone-dn with the same number, so the call will roll over to ephone 1 when ephone-dn with at least 1 channel occupied, because of the huntstop channel command

Scenario 3 - 2 ephone-dn overlays to the same button

ephone-dn 1 dual-line
     number 4001
     preference 1

ephone-dn 2 dual-line
     number 4001
     no huntstop
     huntstop channel

ephone 1
     button 1o1,2

ephone 2
     button 1o1,2

- Both phones will ring.  Say for example ephone 1 answers the call, ephone 2 still able to receive new incoming calls to 4001, and make call using the line 4001
- When ephone 1 answers the call, a new call to 4001 coming in and ephone 2 will ring, without showing call waiting on ephone 1
- If you want call waiting, then use "c" instead of "o"

Tricks of integrating XenDesktop DDC with VMWare vCenter

My environment:  VMWare vCenter 4.1 on Windows 2008 server, ESXi 4.1, Citrix XenDesktop DDC 4

Citrix XenDesktop is the VDI products from Citrix, and it is flexible that the desktop client VM can run on Citrix XenServer and VMWare ESXi.  You can choose your preferred hypervisor for your client VMs.  In my testing I am using ESXi as the hypervisor for the client VMs. 

Integration is needed between Citrix DDC and VMWare vCenter because you need to know which VMs on your ESXi server hosting the client VMs.  During my integration work I have got the following error message in the Create Desktop Group wizard in DDC:

‘Invalid Address – The hosting infrastructure could not be reached at the specified address.’

The workaround is to allow both HTTP and HTTPS for SDK access on vCenter, to do this you can:

1. Edit C:\ProgramData\VMware\VMware VirtualCenter\proxy.xml with your wordpad, and change the access mode of /sdk from httpsWithRedirect to httpAndHttps

<e id="5">
      <_type>vim.ProxyService.LocalServiceSpec</_type>
      <accessMode>httpAndHttps</accessMode>
      <port>8085</port>
      <serverNamespace>/sdk</serverNamespace>
    </e>

2. In DDC, when you are creating integration with vCenter, you can use the URL http://1.2.3.4/sdk where 1.2.3.4 is your vCenter IP address.  You can now allow HTTP access to your vCenter SDK.

Have fun!

How to run Cisco Mobile 8.1 over SSLVPN over 3G

My environment: AnyConnect 2.4.4009 on iPhone, Cisco Mobile 8.1 on iPhone, ASA Software 8.2.3

During my test I have learnt a few tricks that want to share with you guys who want to test / play / deploy it.

1. Setup the TCT device on UCM base on the admin guide here.

2. When you setup the Cisco Mobile, no matter 8.0 or 8.1, when you configure the directory settings, you need to enter port 389 although the field is optional and you are running on default LDAP port.  Otherwise the apps will close by itself!!

3. I have encountered weird problem that my Cisco Mobile registered to UCM, but it can’t make or receive any calls.  The call is either fail to setup, without ring back tone or second call fail.  To solve it, check if you have turned on SIP inspection on ASA.  To turn it off:

policy-map global_policy
class inspection_default
no inspect sip

Good Luck!
