CHAPTER 1
Integration Overview
This release of the EasyCall Gateway has been tested for interoperability with Avaya
S8300/S87xx-Series through an E1 and T1 ISDN-PRI QSIG trunk
The configuration can be done in tandem with EasyCall Gateway installation and
configuration, which includes defining the properties of the telephony system trunk and
defining any changes the EasyCall Gateway makes to telephone numbers before
sending them to the telephony system for dialing. For information about EasyCall
Gateway configuration, refer to the EasyCall Gateway Administrator’s Guide.
Those responsible for configuring the telephone system must take the specific
characteristics of a site into consideration to detemine the settings that are appropriate
for the site. Configuration of the Avaya telephone system for integration with the
EasyCall Gateway is similar to integration with a voicemail system.
The following topics describe how to configure trunks for the supported Avaya
systems.
“Equipment Requirements” on page 1
“Call Detail Records” on page 2
“Integrating with Avaya S8300/S87xx-Series through a QSIG Trunk” on page 3
Equipment Requirements
Only the EasyCall Gateway appliance is required to integrate with the Avaya telephony
system. The following diagram shows the integrated components.

For information on capacity planning, refer to the EasyCall Gateway Administrator’s
Guide.

Call Detail Records
A Call Detail Record (CDR) is a file that contains information about calls placed
through the EasyCall Gateway. Information provided in the CDRs can be used for
billing calls to cost centers and for auditing potential abuse. Each call placed through
EasyCall generates two outbound records.

CHAPTER 2
Integrating with Avaya S8300/S87xx-
Series through a QSIG Trunk
This chapter describes a sample configuration of Avaya S8300/S87xx-Series for
integration with the EasyCall Gateway through an E1 and T1 ISDN-PRI QSIG trunk.
The configuration can be done in tandem with EasyCall Gateway installation and
configuration.
The example configurations are performed through the Avaya Communication
Manager administration software screens, also known as “SAT” (System Access
Terminal) screens. In some instances, the information from the original screen has
been edited for brevity and clarity in presentation.
Those responsible for configuring the telephone system must take the specific
characteristics of a site into consideration to detemine the settings that are appropriate
for the site. Configuration of the Avaya telephone system for integration with the
EasyCall Gateway is similar to integration with a voicemail system.
The following topics describe a sample configuration of Avaya S8300/S87xx-Series:

“Verifying the Integration” on page 13

Prerequisites
DS1 Circuit Pack Configuration
The DS1 circuit pack in the Avaya G650 media gateway must be physically configured
for an appropriate mode (T1 or E1). The DS1 board has 24 channels in T1 mode or 32
channels in E1 mode. The default is set to the T1 mode. To modify the DS1 board to
use it in E1 mode, the dipswitch on the DS1 circuit pack must be switched to the 32
channels side.
Note that the DS1 circuit pack in the Avaya G700 media gateway does not required the
above physical change.
System Parameters
It is assumed that the appropriate Avaya license files and authentication files have
been installed, and that login and password credentials are available to those
responsible for configuring the telephone system. To verify that the installed Avaya
Communication Manager license grants permission to use the features illustrated in
this chapter, use the command “display system-parameters customer-options” as
described in the following procedure. If those features are not enabled, obtain licenses
for the required features from an authorized Avaya account representative.
To verify required features are installed
1. Enter display system-parameters customer-options and go to page 3. Verify
that DS1 MSP is set to y to create an E1/T1 interface.
2. Go to page 4. Verify that ISDN-PRI is set to y.

Chapter 2 Integrating with Avaya S8300/S87xx-Series through a QSIG Trunk 5
3. On page 5, verify that Private Networking is set to y.
4. On page 8, verify that Basic Call Setup, Basic Supplementary Services, and
Supplementary Services with Rerouting are set to y.

Configuring the QSIG Trunk
The following procedures describe the DS1 board configuration for the physical
interface to the EasyCall Gateway:
“Configuring the E1 ISDN-PRI QSIG Trunk” on page 6
“Configuring the T1 ISDN-PRI QSIG Trunk” on page 9
Configuring the E1 ISDN-PRI QSIG Trunk
This topic is specific to E1 trunks. For information on T1 trunks, see “Configuring the
T1 ISDN-PRI QSIG Trunk” on page 9.
To configure the E1 trunk
1. Enter list configuration all and then note the Board Number for the DS1
circuit pack to be configured.
2. Enter add ds1 x, where x is the Board Number of the DS1 circuit pack obtained
from the previous step. Specify the following:
Name = A descriptive name
Bit Rate = 2.048
Line Coding = hdb3
Signaling Mode = isdn-pri
Connect = pbx
Interface = peer-master
CRC = y
Note Since the Interface field for Avaya Communication Manager is set to peermaster,
the EasyCall Gateway Interface field must be set to CPE (peer-slave).

Chapter 2 Integrating with Avaya S8300/S87xx-Series through a QSIG Trunk 7
3. Enter add signaling-group s, where s is an unused signaling group number.
Specify the following:
Group Type = isdn-pri
Primary D-Channel = 001V216
TSC Supplementary Service Protocol = b
Note The Primary D-Channel is 16 on the DS1 circuit pack for an E1.
4. Enter add trunk-group t, where t is an unused trunk group number. On page 1,
specify the following:
Group Type = isdn
Group Name = a descriptive name
TAC = enter a value that is valid under the provisioned dial plan
Carrier Medium = PRI/BRI
Service Type = tie
5. On page 2, set Supplementary Service Protocol to b to indicate that QSIG
supplementary services will be provided on this trunk.

configured in Step 3. Set Trunk Group for Channel Selection to t, where t is
the value of the trunk group configured in Step 4.

Verifying the Integration
To verify path replacement
1. From the Avaya SAT, enter status trunk s, where s is the number of the trunk
group configured in “Configuring the QSIG Trunk” on page 6.
2. Verify that two trunk group members are utilized during the call. Those two trunk
members should be released after a few seconds.
To verify click-to-call
1. Use the Communication Agent to place a call from an application running on the
desktop. After you pick up the call (on the phone profiled to receive click-to-call
calls), the phone being dialed should ring.
2. Enter status trunk s, where s is the number of the trunk group configured in
“Configuring the QSIG Trunk” on page 6.
3. Verify that two trunk group members are utilized. As the phone you dialed goes
off-hook, the two trunk members should be released after a few seconds.
