4.2.  Editing Configuration Files

• 4.2.1.  Configuration File Location
• 4.2.2.  Editing the gateway_r4.cfg File

This section discusses how to configure the demo for your system. It contains the following topics:

• Configuration file location
• Editing the gateway_r4.cfg File

4.2.1.  Configuration File Location

Before running the IP Gateway (Global Call) demo, modify the gateway_r4.cfg file to reflect your system environment. Use a text editor and open the file from:

• Windows: C:\Program Files\dialogic\demos\ipt_demos\gateway_r4\release\
• Linux: /usr/dialogic/demos/ipt_demos/gateway_r4

4.2.2.  Editing the gateway_r4.cfg File

Below is an example of the gateway_r4.cfg file. Update the following information:

ipProtocol

The IP Protocol used for opening the IP Line devices, values: H323, SIP, both

Channel

Channels defined by this section of the file - may be individual channel or a range of channels

Source

Source address

Destination

Destination address

RemotePhoneNumber

Destination phone number to call. Transferred during call establishment to target gateway.

LocalPhoneNumber

The number used for PSTN calls

pstnProtocol

PSTN protocol to use

DTMFmode

One of the following: OutOfBand, inband, rfc2833

AudioRxCodecs

Capability for receive audio codecs. The following capabilities are defined:

• CoderType - preferred coder. Recognized coders are:

· g711Alaw

· g711Mulaw

· gsm

· gsmEFR

· g723_5_3k

· g723_6_3k

· g729a

· g729ab

• CoderFramesPerPkt - frames per packet for the selected coder
• CoderVAD - Voice Activity Detection on/off

AudioTxCodecs

Capability for transmit audio codecs. See AudioRxCodecs for a complete description.

DataCodecs

Capability for fax codecs. The demo currently support T38 only.

MediaAlarmLostPackets

Indicates that the percentage of packets lost during a call exceeded its threshold value

• Threshold - defines when a Quality of Service (QoS) parameter is in a fault condition. A fault occurs when the result of a measurement of a QoS parameter crossed the Threshold value. Default = 20.
• DebounceOn - the time during which faults are measured (in msec., must be a multiple of Interval). Default = 10000.
• DebounceOff - the dime during which successes are measured (in mesc., must be a multiple of Interval). Default = 10000.
• Interval - the amount of time between two QoS parameter measurements (in multiples of 100 msec). Default = 1000.
• PercentSuccess - the threshold of successes during the DebounceOn time (expressed as a percentage of successes). Default = 60.
• PercentFail - the threshold of failures during the DebounceOn time (expressed as a percentage of failures). Default = 40.

MediaAlarmJitter

Indicates that the jitter (as defined in RFC 1889) exceeded its threshold value

• Threshold - Default = 60.
• DebounceOn - Default = 20000.
• DebounceOff - Default = 60000.
• Interval - Default = 5000.
• PercentSuccess - Default = 60.
• PercentFail - Default = 40.

Display

Display information passed to destination gateway during call establishment

IPT_UUI

User to User Information string. Information sent before Connected state.

UII

User Input Indication string to send

NonStdParm

Non-standard parameter data to send

NonStdCmd

Non-standard command string to send

ObjId

Object ID

Q931Facility

Facility data to send on the Q.931 channel

DTMF

DTMF mode. Possible options: OutOfBand, inband, rfc2833

enableRegestration

Register with gatekeeper

TTL

Time-to-live parameter (in seconds)

Protocol

Call control protocol. Possible values: h323, SIP, both

max_hops

Maximum number of router hops

regServerAddress

Gatekeeper IP address. Use 0.0.0.0 as the default address for discovering the GK

NonStdRasCmd

Non-standard RAS command string to send

RasObjId

RAS object ID

Alias

Possible alias types: 1 = string, 2 = IP address, 3 = H323 ID, 4 = phone, 5 = URL, 6 = EMail
