Preparing the Cisco CallManager and
Octel Systems

Because the DPA 7630 depends on information from the Cisco CallManager and
the Octelsystems, you must verify thatthey areset upproperly beforeconfiguring
the DPA 7630, and you must obtain some information from these systems to set
up the DPA 7630.

This guide does not contain details about configuringthe Cisco CallManager and
Octel systems. Refer to the documentation provided with these systems for
installation and configuration instructions.

These sections provide details about the configuration requirements on the
Cisco CallManager and Octel systems:

• Configuring Cisco CallManager, page 3-2

• Configuring the Octel Systems, page 3-13

Overview of Required Tasks

Cisco CallManager recognizes the DPA 7630 as another IP telephony device. So,
to add the device to the database, you need some information from the DPA 7630.
Additionally, to set up the DPA 7630, you need information from both the
Cisco CallManager and Octel systems. Refer to Table 3-1 for an overview of the
tasks and information you need from them to configure the DPA 7630.

Configuring Cisco CallManager

The DPA requires minor changes to Cisco CallManager because when you add
the DPA7630 tothe IP network, Cisco CallManager recognizesthe portsas Cisco
IP Phones. Therefore, you need to add these ports to the Cisco CallManager
database.

The DPA 7630 connects to Cisco CallManager to provide the following
capabilities:

• Access from the Cisco IP Phones to the voice messaging system on the Octel

systems.
The DPA 7630 provides connection to the Octel voice messaging system by

emulating IP phones. These emulated phones appear in the
Cisco CallManager database.

Chapter 3 Preparing the Cisco CallManager and Octel Systems

• Proper signaling to the message waiting indicators (MWI) on the Cisco IP

Phones.
Some ports on the DPA7630 handle MWI commands from the Octel system.

An additional “virtual” IP phone sends these messages to the
Cisco CallManager system. Cisco CallManager then sets the MWI on the
Cisco IP Phones.

When reviewing the following tasks, if you need additional instructions, refer to
the Cisco CallManager Administration Guide or the online help in the
Cisco CallManager application:

• Adding the DPA 7630 to Cisco CallManager, page 3-3

• Configuring the DPA Ports and Phones, page 3-5

• Enabling the Message Waiting Light, page 3-10

• Setting Up the Voice Mail Hunt Group, page 3-11

Adding the DPA 7630 to Cisco CallManager

Configuring Cisco CallManager

When the DPA 7630 and Cisco CallManager connect, the ports on the DPA 7630
appear as IP phones in the Cisco CallManager database. An additional “virtual”
port also appears as an IP phone to Cisco CallManager, but it does not have any
correspondence to a physical port. It is created by the DPA 7630 to handle MWI
commands to Cisco CallManager.

Using Auto-Registration

You can choose to havethe DPA 7630 automatically added to Cisco CallManager
using auto-registration. If you want to use auto-registration, you must verify that
it is enabled in Cisco CallManager. Refer to the Cisco CallManager
Administration Guide or online help in the Cisco CallManager application for
details.

Through auto-registration, when the DPA 7630 connects to Cisco CallManager,
the ports connected between the DPA 7630 and the Octel system are registered as
Cisco IP Phones in the database. These ports are actually emulated IP phones that
are used to access the voice mail system and to send MWI commands from Octel.

Configuring Cisco CallManager

Cisco CallManager only recognizes these IP phones after the Octel voice mail
system is up and running.So, verifythat theOctel system and the Cisco DPA7630
are up before completing these tasks in Cisco CallManager.

Auto-registration automatically assigns phones a directory number. The directory
number assigned is the next one available in sequential order within the device
pool assigned to this phone type in Cisco CallManager. However, if you need to,
you can modify this directory number for each emulated phone (see the
“Configuring the DPA Ports and Phones” section on page 3-5).

During auto registration, thehost name assigned to the DPA7630 is entered in the
Description field in the record for the emulated phone in Cisco CallManager. If
you do not enter a host name, the following sequence applies for the device
description: SEP + the last 10 digits of the MAC address.

Additionally,Cisco CallManager requires unique MACaddresses for all devices,
but all 24 ports on the DPA 7630 share the same MAC address. Therefore, an
automatic conversion process converts the MAC addresses into this format:

1. The first two digits for the MAC address are dropped.

2. The number is shifted two places to the left.

3. The two-digit port number is added to the right.

For example, if the MAC address is

000039A44218

the MAC address registered for port 12 in CallManager is

0039A4421812

The 25th virtual port is automatically assigned the MAC address of
0039A4421825.

Chapter 3 Preparing the Cisco CallManager and Octel Systems

Adding the DPA 7630 Manually

If you want to assign specificdirectory numbers to the emulated IP phones on the
DPA 7630 without using auto-registration, you must manually add each phone to
the Cisco CallManager database. Keep in mind several important facts:

• Each port must have a unique MAC address. Use the auto-registration

formula.

• Use the host name or other name for the Description for each port. Use the

same name for ports configured on the same DPA 7630 system.

• Add each port on the DPA 7630 as a Cisco IP Phone 30 VIP.

Chapter 3 Preparing the Cisco CallManager and Octel Systems

Configuring the DPA Ports and Phones

From the perspective of the DPA 7630, several types of ports exist:

• Call ports—Handle call processing (incoming and outgoing calls).

• Octel MWI ports—Receive MWI commands from the Octel system.

• Virtual port—Send MWI commands to Cisco CallManager.

• PBX MWI ports—Send MWI on the Lucent PBX system and is only present

in the hybrid integration mode.

To Cisco CallManager, these ports on the DPA appear as IP phones, but the PBX
MWI ports do not appear in Cisco CallManager.The Cisco CallManager database
also containsrecords of all the end-user phones. You mustconfigure each of these
phones properly in Cisco CallManager to ensure that calls areprocessed properly.
You access the phones using the Devices > Phone menu in Cisco CallManager.

These sections provide details about the required settings in Cisco CallManager
for the different ports:

• Configuring Call Ports, page 3-5

• Configuring Octel MWI Ports, page 3-7

• Configuring the Virtual Port, page 3-8

• Configuring an End-User Phone, page 3-9

Configuring Cisco CallManager

Configuring Call Ports

Use call ports to connect lines from the Octel system that handle incoming
messages, such as voice mail access, and outgoing calls such as fax calls,
outgoing calls to pagers, and so on. However, a particular line from the Octel
system must support either incoming or outgoing calls; it cannot support both.

Outgoing Calls

Do not include the call ports supporting outgoing calls in the voice mail hunt
groups. Otherwise, configure these lines in Cisco CallManager as you normally
would, assigning directory numbers to them.
