CUCME-CUE Lab 5 – Advanced CUCME Call Features

Now that there is basic call connectivity between each location as well as to the PSTN, Fuzzy Dunlop is interested in implementing some advanced calling features.

Note, when I started researching and developing this lab, CUCME 7.1 had not yet been released. However, since that time, I have noticed CUCME 7.1 files are now posted on CCO, and the Cisco Unified Communications Manager Express System Administrator Guide reflects many of these new updates. Therefore, some tasks that did not work with SIP phones under CUCME 7.0 but are now supported under CUCME 7.1 shall be added in a later lab.

Lab 5.1 –Advanced CUCME Call Features Configuration Tasks
1. On each phone, modify the Phone Head Bar Display to reflect the phone’s E.164 phone number.

2. On each phone, modify the existing labels next to each line appearance to reflect the four-digit extension as well as the primary owner’s name.

3. Ensure that the name associated with each calling party’s extension when a call is ringing on another IP phone is properly displayed.

4. Ensure that the local directory include listings for the all users, including those at the remote location.

5. In Baltimore, configure a hunt-group that contains Arliss Michaels and Cal Ripken as members. However, Arliss should always be first person to receive a call. Assign extension 1050 to this hunt group.

6. In New York, configure a configure a hunt-group with extension number 2050. Ari Gold and Tom Seaver should be assigned to this hunt-group, and phones should ring in a round-robin fashion, based on the last phone that rang. However, Ari’s extension should appear first.

7. In Baltimore, create a call-park with extension 1800. Anyone who parks a call should be reminded every 30 seconds, up to 10 reminders. Joe Flacco should be prevented from parking calls using the transfer key.

8. Cal Ripken would like to be to have an intercom to Arliss, and vice versa. However, no one else in Ballplayers, LLC should be able to dial this set on intercoms. The intercom should be configured so that each party can talk to each other without any manual intervention. Each side should also have a visual display indicating the name of the individual on the other side of the intercom.

9. Cal Ripken and Nick Markakis should belong to a paging group called Orioles.

10. Joe Flacco and Ray Lewis should below to a paging group called Ravens.

11. Both groups should be combined into a paging group called All Baltimore Sports. Arliss should be included in this group.

12. Ensure the paging configuration can exceed 10 IP Phones in the future, if necessary.


Lab 5.2 –Advanced CUCME Call Features Verification
Many of the tasks described in this lab were based off of either Chapter 15 of the Cisco Press release, Cisco IP Communications Express: CallManager Express with Cisco Unity Express or from the Cisco Unified Communications Manager Express System Administrator Guide. I’ll do my best below to provide references where appropriate.


1. On the Baltimore (SCCP) CUCME, modifying the Phone Head Bar Display, the line appearance labels, and Caller-ID Name are performed under ephone-dn configuration. For example, Cal Ripken is configured as follows:

ephone-dn 1 dual-line
number 1001
label Cal Ripken 1001 #sets the line appearance #
description 410-555-1001 #sets the Phone Head Bar Display#
name Cal Ripken #sets Caller-ID Name#

2. For SIP Phones (NY CUCME), the configuration is slightly different. The Caller-ID Name and the line appearance labels are modified under the dn configuration, while the Phone Head Bar Display is modified under the phone itself. For example, Tom Seaver’s modifications are as follows:

voice register dn 1
number 2001
name Tom Seaver #sets Caller-ID Name#
label Tom Seaver 2001 #sets the line appearance #
!
!
voice register pool 1
id mac 0021.D8BA.2373
type 7942
number 1 dn 1
description 212-555-2001 #sets the Phone Head Bar Display#

3. To ensure that the Baltimore users have NY users in their local phone directories, and vice versa, you need to manually add those entries for the remote site. In Baltimore, to add the NY users, the configuration is as follows:

telephony-service
directory entry 1 2001 name Tom Seaver
directory entry 2 2002 name David Wright
directory entry 3 2003 name Eli Manning
directory entry 4 2004 name Brandon Jacobs
directory entry 5 2005 name Ari Gold

4. The Configuring Call-Coverage Features chapter covers the SCCP hunt group configuration options. The hunt group described for Baltimore is a sequential hunt group. The key is to make sure you address the multiple calls on a single line by adding the appropriate huntstop commands under the appropriate dns.

The first step is to configure ephone-hunt parameters. Secondly, you modify the ephone-dn huntstop parameters for the dns that are members of the hunt group. Note that since Arliss’s dn is an octo-line, you must explicitly state which channel the hunting should stop on.

ephone-hunt 1 sequential
pilot 1050 secondary 4105551050
list 1005, 1001
!
ephone-dn 1 dual-line
huntstop channel
!
ephone-dn 5 octo-line
huntstop channel 1

5. The hunt-group described for New York is a peer hunt group. Initially, I found the CUCME 7.0 documentation pertaining to SIP Hunt Groups to be “ambiguous”. The updated CUCME 7.1 chapter on Configuring Call-Coverage Features, and specifically the Configuring Voice Hunt Groups section is an improvement, but I still found the “Cisco Unified Communications Manager Express: SIP Implementation Guide” to be much clearer. Below are the configuration components for the NY CUCME SIP Hunt Group.

voice hunt-group 1 peer
list 2005,2001
timeout 180
pilot 2050
!
voice register dn 1
huntstop
!
voice register dn 5
huntstop

6. A common “CCIE gotchya” is to instruct you to configure something, and the candidate “over interprets” the task. For the call park task, the configuration seems pretty straight-forward, with the curve ball (pardon the pun) of preventing Joe Flacco from transferring a call to the park slot.

In the configuration below, an ephone-dn is created for park slot 1800. Joe Flacco’s phone is prevented from dialing 1800 to transfer to the park slot. However, the task does not explicitly state to remove this feature from the soft key template, so Joe can still park a call this way.

One final note, when I began developing this lab, SIP lines did not support call park. This is now supported under CUCME 7.1!

ephone-dn 6
number 1800
park-slot timeout 30 limit 10
!
ephone 3
transfer-park blocked
description Joe Flacco

7. Intercom configuration for SCCP phones is described in the Configuring Intercom Lines chapter of the Cisco Unified Communications Manager Express System Administrator Guide. The chapter also covers Intercom configuration for SIP, which I could not get to work properly based on the example provided. If anyone else has manager to get SIP Intercom working, I’d love to hear your feedback and suggestion.

Note the requirement that the Intercom numbers between Cal Ripken and Arliss Michaels be private; prepending the dn with a letter adresses this requirement.

ephone-dn 7
number A9990
label Intercom to Arliss
intercom A9991 no-mute label "Arliss"
!
!
ephone-dn 8
number A9991
label Intercom to Cal Ripken
intercom A9990 no-mute label "Cal"
!
ephone 1
description Cal Ripken
button 1:1 2:7
!
ephone 5
description Arliss Michaels
button 1:5 2:8

8. Finally, the paging group feature is seemingly a straight-forward configuration task, with a hidden gotchya. Recall the task stating “the paging configuration can exceed 10 IP Phones in the future.” A careful read of the Configuring Paging chapter of the Cisco Unified Communications Manager Express System Administrator Guide would reveal that if multicast paging is not implemented, the maximum number of unicast transmission is limited to 10 IP Phones. This is another example where if a candidate does not carefully read the task, he could easily loose all the points associated with this sub-section of the actual lab!

ephone-dn 9
number 1500
name Orioles
paging ip 239.0.1.9 port 2000

ephone-dn 10

CUCME-CUE Lab 5 Wrap-up
With the release of CUCME 7.1, I will try to address additional line-side features in the next lab. I’ll also plan to cover transcoding, in order to position for later CUE labs.
