About Norstar VoIP Gateway

p18 Figure 2 Typical VoIP Gateway Installation

This diagram indicates that the internet is the IP network connecting the gateways

(via routers). The public internet should not be used for this connection. Rather,

the network should be a secure corporate intranet, ideally engineered for voice

quality of service, which could include VPN connections through the public

internet.

Configuring the VoIP Gateway

Configuring the Protocol Definition

p30 Step 4 refers to Table 4 which describes various protocol definition parameters.

The description of the following parameters should be changed as shown below:

p30 Parameter Description

Connection Mode Select Normal if you want the VoIP Gateway to use the Normal

connection mode.

Select Tunneling to have H.245 messages added to H.225

messages during call setup.

Select Fast Start if you want the VoIP Gateway to use the Fast

Start connection mode.

Select Fast Start+Tunneling to combine the two options.

The default value is Fast Start.

The Fast Start connection mode allows a media path to be

established using H.225 without having to start the full H.245

protocol session. In some situations, you need to use fast start

in order to control call progress tones.

Tunneling allows full H.245 session establishment at the same

time that H.225 call setup occurs which can be more efficient

and facilitate interworking with some third party products.

string is added to the gateway registration when you select

H.323-ID, E.164 & H.323-ID, or NPI/TON & H.323-ID.

p40 Step 7 refers to the Save Configuration button. If a reset has been performed, all

changes will be saved to non-volatile memory. The only time that you must click

the Save Configuration button is when changes are made without performing a

reset. Similarly, the Note that follows step 7 should be ignored. When a reset is

performed, all new values are stored in non-volatile memory and are not restored

after a power cycle.

Norstar VoIP Gateway Configuration Guide Addendum – Version 2.1 4

Configuring the Number Manipulation tables

Configuring number manipulation for Digit Delivery

p51 Parameter Description

Prefix to add Enter the number you want to add to the front of the stripped

destination number.

For example, if you enter 9 and the stripped destination phone

number is 1234, the new destination phone number is 91234.

The prefix can include digits and the following:

• D = wait for dial tone.

You may use D as the first prefix digit so that the VoIP

Gateway will wait for a Norstar dial tone before dialing out

the digits. Dial tone detection can only be used as the first

digit.

• P = pause

Pause inserts a 1.5 second wait period before proceeding

with the remaining digits. It can be used instead of D as the

first digit and may improve call setup time in that case. It

may also be used to wait for any secondary dial tone, such

as might be required for dialing out through the Norstar to

the PSTN. Longer periods may be achieved by using more

than one P character. For example, PP will insert a pause

of 3.0 seconds.

Note: Either D or P should be used at the beginning of the digit

string in order to ensure that the Norstar has enough time to be

ready to receive the digits. Without D or P, the first few digits

may not be reliably dialed.

Configuring the Norstar System

Configuring your Norstar KSU / Required Norstar Hardware

p111 In addition to the hardware requirements indicated in this section, the Norstar

KSU must also have DTMF tone receivers installed in order to use “target line

capability”. Target Lines is the mode used to automatically dial through to the

target set or other line at the destination KSU. In this mode, the Norstar

automatically answers the ringing trunk and presents dial tone to the gateway.

The gateway either detects this dial tone (when using the “D’ parameter in the

Digit Delivery Table) or waits for 1.5 seconds (when using the “P” parameter in

the Digit Delivery Table) and then dials the destination digits into the trunk.

Norstar detects these digits and connects the call through to the required

destination. In order to do this, the Norstar must have DTMF tone receivers

available.

DTMF tone receivers are provided when using any of the following:

1. Services card

2. Combo card

3. E&M trunk card
