Configuration examples for setting up an Cisco ASA to allow Split Tunneling (Local LAN Access) to VPN Clients. http://www.cisco.com/en/US/products/ps6120/products_configuration_example09186a0080702999.shtml

Sets up routes to networks accessible over the tunnel while allow the default route to remain the local default.

Just doing a little reading on the possibilities of running Cisco Call Manager (Unified Communications), Unity, and CRS (UCCX) in a virtual environment.

Cisco actually supports running Unity as a virtual machine guest in ESX. The Desgin Guide is here http://www.cisco.com/en/US/docs/voice_ip_comm/unity/virtualization_design/guide/cuvirtualdg010.html

Cisco does not support Vmotion, HA, or iSCSI attached storage for a virtualized Unity box. They also do not support a physical to virtual conversion of a Unity server. Hopefully Cisco will support Vmotion and HA at some point.

I also found some interesting information on running an older Call Manager version (4.x) as a VM – http://www.blindhog.net/cisco-install-call-manager-4x-with-vmware/

Here is some info I found on UCCX – http://tannerezell.com/cisco/?p=85

We recently increased our Internet bandwidth from a single 1.54Mbps T1 to what Verizon calls 3Mbps Bonded Service.  This takes two 1.54Mbps T1s and puts them in a ppp multilink group to double your bandwidth.

Here is the quick and dirty configuration for bonding two Serial (T1) PPP links on a Cisco 1841 router.

interface Mulitlink1
ip address xxx.xxx.xxx.xxx xxx.xxx.xxx.xxx
ppp multilink
ppp multilink group 1

interface Serial 0/0
no ip address
encapsulation ppp
ppp multilink
ppp multilink group 1

interface Serial 0/1
no ip address
encapsulation ppp
ppp multilink
ppp multilink group 1

The two serial interfaces then look like one – the Multilink1 interface.  The PPP ip address for this end will be the ip address of the Multilink1 interface. You can still check the status of each serial interface using “show interface serial 0/x” .  This will also show you what Multilink group the serial interface is a member of

Link is a member of Multilink bundle Multilink1

You can also check the status of the Multilink interface by using “show interface Multilink1″.  The command “show ppp multilink interface multilink1″ will display what interfaces belong to the multilink group (useful if you are on a larger router with multiple multilink ppp groups).

I have set up these multilink interfaces in the past, but I can say I am not sure what happens if just one of the T1s fail.  I would guess that the PPP would not like this and bring the whole interface down.

Does losing one T1 bring the whole Multilink interface down or will it the protocol stay up? Is there a better way to do this that will keep the interface up if one of the T1s fail?

Going to have to test this when I get a chance.

Received a request from our CEO the other day, he wanted to be able to just click on a contact in his Outlook Contacts and have it dial their number on his Cisco IP Phone.

Cisco has a plugin called Click to Call that let’s you do just that.

Follow these instructions from Cisco to set it up.

Pretty painless.  Make sure the device you are dialing from is associated with your Call Manager End User. Also remember that Application Dial Rules are applied in order – this table gives you a good example of the dial rules.

It is more than just a click in Outlook, you have to select Additional Actions from the right click menu, but it does allow you to select which number for the contact you want to call (Business, Work, Cell).

I think the coolest thing about this little app is being able to dial directly from FireFox or IE.  Just highlight the number on a webpage, right click, Call.

Got an email earlier today about how to adjust (shorten) the call wrap up time on one of our queues in Cisco CRS.  I thought this could be done using Desktop Administrator but I guess I was wrong, or at least I could not find  where to do it there.

As far as I can tell it has to be done through the CRS Appadmin site.  Log into the CRS  Web Administration select  SubSystems -> RmCm from the top menu.  Select Contact Services Queue and then select the queue you want to modify and there it is.  Set the Wrap Up Time to the number of seconds the agent is given to do any “wrap up” once the call disconnects.
