Cisco CME and Lync Simultaneous Ringing using Cisco SNR Feature

Cisco has a Single number reach feature that allows calls to ring more than one number. Think of it as a parallel hunt group but with the option to turn it off and on from the user's phone.

With this setup, the end user's Lync client and Cisco phone will ring a the same time.

Lync (Skype for Business) setup

Create PSTN Gateways
 - use the IP address of the CME

Create the Trunks
- Listening on port 5060 and Mediation port 5068.

Enable Enterprise Voice for user's account.

Assign a fake number to the Line URI in the user's account setup
(Example of user with extension 4025 would be Tel:+13065554025)

* You can also create a CME Dial Plan and a CME Voice Policy to allow Lync users to call out on the CME's phone lines from their Lync client.

- If you are using Voice and Data Vlans on your CME, bind it to the CME same Vlan used by the Lync server.

Cisco CME Station ID for DID FXS FXO Port Config

In my previous post "Dealing with Multiple Incoming Phone Lines - Cisco CME", you will know we were looking for a way to monitor incoming calls and report prank calls.

In searching for Caller ID programming on a Cisco CME, I came across the station-id command for FXO, FXS and DID ports.

Since we are not subscribing to our Telco providers incoming call display, this command allows us to assign a name (or number) to calls coming in on the voice-ports.

If we were using the Telco's call display, we would need to use the ephone-dn forwarding setup in the previously mentioned post.



Incoming Call

Now all incoming and outgoing calls are now labeled with the Line 50x and DID 30x. (x referring to the line number)

voice-port 0/0/0
  station-id name Line 501
.
.
.
voice-port 0/1/3
 station-id name Line 508



Outgoing Call

Why use 50x and 30x?  - Park codes are 10x and if you look at the dial pad L is #5 and D is #3.

Since we can't call out on a DID port, the station-id helps us report troubles to our Telco provider.

The station-id number command would assign a E164 number to that port.  However, some people might get confused and think that is the number of the person calling.

We using the FXS port for paging, so we simply call it "Paging".

voice-port 0/2/0
 station-id name Paging

Call History Reporting via the Cisco CME GUI for End Users

Over the years, people or students have accidentally dialed 911 and in some cases the police are dispatched.

Then we (IT department) get the call wanting to know who called 911 or do we log outgoing calls.

Without video surveillance pointed at every phone, it's hard to say who was the one dialing, but the call history on the CME GUI could at least report which extension.

Changed the default logging in the CME configuration to...

dial-control-mib retain-timer 10080
dial-control-mib max-size 500

To reduce my work load and give the locations a quicker response to the "Who called 911?" question,
I began looking for a way to allow the locations to access the CME web GUI but not have the ability to may any changes to the system.

After following the GUI install from this website and hiding everything in the XML template...

telephony-service
  web admin customer name Report password Password
  web customize load flash:callreport.xml

The customer account still had the ability to may changes to the configuration.

After searching the internet for how to edit the ccme.html file and finding that the file is not really a file... the next stop was the .js files in the GUI folder.

Knowing nothing about JavaScript, I opened the admin_user.js file in Notepad++ and started looking for some keywords.

Found the Extensions, phones, users and system parameters and was about to cut out the code lines when I noticed the "Block comment" option when I right clicked on the selection.

So I started commenting out line by line and eventually came up with these changes and now any user (even the admin account) that logs into the CME web interface will only be able to access the Call history. - Let face it, when was the last time you configured the CME via Cisco's GUI.

Copied the new admin_user.js file to the tftp server and then downloaded it to the CME.

Changes to the admin_user.js file starting at about line 72 in the version installed on the cme. (Copied the original to admin_userbk.js - Just in case)

Tip - Comment each line as you go and then reload to make sure it is working. - In Notepad++ it's just a right click and "Block Comment" on each line or select more than one line.

Dealing with Multiple Incoming Phone Lines - Cisco CME

When our first Cisco CME system was installed, we were told that there wasn't a way to report nuisance calls or block outgoing caller id because the incoming phone lines were programmed into trunk groups.

About 4 years and 16 CME systems later, the IT Department is now deploying the CME systems and we are still asked if this is possible.  Mostly to report nuisance calls, the odd time to block outgoing caller id.

Today I have found a solution to this question for standard phone lines.  This will not work on DID calls as they are only incoming.

In our previous CME configuration, the incoming lines were all forwarded to one DN and appeared as one DN on the main admin phone.  This confused some staff as they were used to having 3 or more line buttons on the Nortel, Norstar or Meridian phones.

In smaller locations, with only 2 or 3 phone lines, we could go with the individual DNs showing up on the phone as individual DNs and then forward to one voice mailbox.  However, some years the Admin assistants are moved around from location to another location so we want to keep things as consistent as possible in our 30+ locations.

In the new configuration...

The incoming calls will forward to their own separate DN (5xx) via the connection plar command in the voice port configuration.

The 5xx DN will then forward onto the main DN (5400).

Example: A call comes in on Line 1 (FXO 0/0/0), it will show up as a forwarded call from the 501 DN.

 



Now let's say this was a prank call and they want to report it to our telephone provider.

In the old configuration, it would pick the first available phone line out, which would be Line 4...3...2...1 in the example below.  Very often the outgoing call would not pick the same line that the call came in on, so that increase the chances of not working or a false report being filed.

In the new configuration...
The person sees that the call came in on L01 5551212 (501) aka Line 1
Now to report the call to the provider, they dial 9501*57 and the call goes out on Line 1 (FXO port 0/0/0)  and *57 is dialed. (Based on dial-peer voice 500 pots)

If the call came in on L03 5551214 (503) aka Line 3, they would dial 9503*57 and the call would be handled by dial-peer 502

The new 5xx dial peers also allows for calling out on the specific line to do troubleshooting with service providers.

Here's the new configuration.
