5. Key entry cannot be deleted but the phone may prompt error once it is detected

FIRMWARE VERSION 1.0.14.1 GXW400X USER MANUAL Page 18 of 60

PLACING A PHONE CALL

PHONE OR EXTENSION NUMBERS

1. Dial the number directly and wait for 4 seconds (To change the default value, modify the following

setting - “No Key Entry Timeout”)

2. Dial the number directly and press # (Use # as dial key” must be configured in web configuration).

Examples:

1. Dial a number (e.g. (626) 666-7890), first enter the prefix number (usually 1+ or international

code) followed by the phone number. Press # or wait for 4 seconds. Check with your VoIP

service provider for further details on prefix numbers.

DIRECT IP CALLS

Direct IP calling allows two parties, that is, a FXS Port with an analog phone and another VoIP Device, to

talk to each other in an ad hoc fashion without a SIP proxy.

Elements necessary to completing a Direct IP Call:

1. Both GXW400X and other VoIP Device, have public IP addresses, or

2. Both GXW400X and other VoIP Device are on the same LAN using private IP addresses, or

3. Both GXW400X and other VoIP Device can be connected through a router using public or private

IP addresses (with necessary port forwarding or DMZ).

GXW400X supports two ways to make Direct IP Calling:

Using IVR

1. Pick up the analog phone then access the voice menu prompt by dial “***”

2. Dial “47” to access the direct IP call menu

3. Enter the IP address using format ex. 192*168*0*160 after the dial tone.

Using Star Code

1. Pick up the analog phone then dial “*47”

2. Enter the target IP address using same format as above.

Note: NO dial tone will be played between step 1 and 2.

FIRMWARE VERSION 1.0.14.1 GXW400X USER MANUAL Page 19 of 60

Destination ports can be specified by using “*” (encoding for “:”) followed by the port number.

Examples:

a) If the target IP address is 192.168.0.160, the dialing convention is

*47 or Voice Prompt with option 47, then 192*168*0*160.

Followed by pressing the “#” key if it is configured as a send key or wait 4 seconds. In this case,

the default destination port 5060 is used if no port is specified.

b) If the target IP address/port is 192.168.1.20:5062, then the dialing convention would be:

*47 or Voice Prompt with option 47, then 192*168*0*160*5062 followed by pressing the “#” key

if it is configured as a send key or wait for 4 seconds.

NOTE: When completing direct IP call, the “Use Random Port” should set to “NO”. You can not make

direct IP calls between FXS ports since they are using same IP.

CALL HOLD

Place a call on hold by pressing the “flash” button on the analog phone (if the phone has that button).

Press the “flash” button again to release the previously held Caller and resume conversation. If no “flash”

button is available, use “hook flash” (toggle on-off hook quickly). You may drop a call using hook flash.

CALL WAITING

Call waiting tone (2 short beeps) indicates an incoming call, if the call waiting feature is enabled. Toggle

between incoming call and current call by pressing the “flash” button. First call is placed on hold. Press

the “flash” button to toggle between two active calls.

CALL TRANSFER

BLIND TRANSFER

Assume that call Caller A and B are in conversation. A wants to Blind Transfer B to C:

3. Caller A presses FLASH on the analog phone to hear the dial tone.

4. Caller A dials *87 then dials caller C’s number, and then # (or wait for 4 seconds).

5. Caller A will hear the dial tone. Then, A can hang up.

FIRMWARE VERSION 1.0.14.1 GXW400X USER MANUAL Page 20 of 60

NOTE: “Enable Call Feature” must be set to “Yes” in web configuration page.

ATTENDED TRANSFER

Assume that Caller A and B are in conversation. Caller A wants to Attend Transfer B to C:

1. Caller A presses FLASH on the analog phone for dial tone.

2. Caller A then dials Caller C’s number followed by # (or wait for 4 seconds).

3. If Caller C answers the call, Caller A and Caller C are in conversation. Then A can hang up to

complete transfer.

4. If Caller C does not answer the call, Caller A can press “flash” to resume call with Caller B.

NOTE: When Attended Transfer fails and A hangs up, the GXW400X will ring back user A to remind A

that B is still on the call. A can pick up the phone to resume conversation with B.

3-WAY CONFERENCING

The GXW400X supports Bellcore style 3-way Conference.

Instructions for 3-way conference:

Assuming that call party A and B are in conversation. A (GXW400X) wants to bring C in a conference:

1. A presses FLASH (on the analog phone, or Hook Flash for old model phones) to get a dial

tone.

2. A dials C’s number then # (or wait for 4 seconds).

3. If C answers the call, then A presses FLASH to bring B, C in the conference.

4. If C does not answer the call, A can press FLASH back to talk to B.

5. If A presses FLASH during conference, C will be dropped out.

6. If A hangs up, the conference will be terminated for all three parties when configuration

“Transfer on Conference Hangup” is set to “No”. If the configuration is set to “Yes”, A will

transfer B to C so that B and C can continue the conversation.

HUNTING GROUP

This feature allows the user to setup a single SIP account on the gateway and have the ability to use all

FXS ports to make/receive calls. Using this feature, all ports active in same Hunting Group will have the

same phone number and incoming calls will be distributed in a Linear or Circular manner among the ports

FIRMWARE VERSION 1.0.14.1 GXW400X USER MANUAL Page 21 of 60

active in that Hunting Group. The number of hunting groups is limited by the number of ports each GXW

model has - i.e. each port can be its own Hunting Group. The most practical and efficient way to use

Hunting Groups is to assign 2 or 3 ports to separate Hunting Groups.

One additional and popular way to use the Hunting Group feature is called “multiplexed analog lines”. In

this configuration, a legacy PBX system with 8 FXO trunks can be connected to 8 GXW 4008 ports

configured as Hunting Group. The GXW can be registered to a SIP server provider using only one phone

number. If the SIP service provider allows multiple calls to the same number, the GXW will allow 8

concurrent calls to the same SIP number. All office members can be reached remotely using the same

phone number in a round-robin fashion.

Example Configuration of a typical Hunting Group:

1. Configure the SIP account from your VoIP Service Provider on FXS port 1 under FXS Ports

webpage.

2. Select Active under the Hunting Group drop box for FXS port 1.

3. For the remaining ports (say 2, 3 and 4) select 1 for Hunting Group. Ports 2, 3 and 4 are now

active members of the hunting group associated with port 1.

This configuration will route all calls directed to FXS port 1 to ports 2, 3 and/or 4 in round robin fashion

respectively if port 1 is busy or times out. You can configure the ring timeout on the Profile page.

Example configuration of a multiple Hunting Group:

FXS Port #1: SIP UserID and Authenticate ID entered, Hunting group set to "Active"

FXS Port #2: SIP UserID and Authenticate ID left blank, Hunting Group set to "1"

FXS Port #3: SIP UserID and Authenticate ID left blank, Hunting Group set to "1"

FXS Port #4: SIP UserID and Authenticate ID entered, Hunting group set to "Active"

FXS Port #5: SIP UserID and Authenticate ID left blank, Hunting Group set to "4"

FXS Port #6: SIP UserID and Authenticate ID left blank, Hunting Group set to "4"

FXS Port #7: SIP UserID and Authenticate ID entered, Hunting group set to "Active"

FXS Port #8: SIP UserID and Authenticate ID left blank, Hunting Group set to "7"

Hunting Group 1 contains ports 1, 2, 3. Hunting Group 4 contains ports 4, 5, 6.

Hunting Group 7 contains ports 7, 8.

Please be aware, the choice of 1 for ports 2 and 3, the choice of 4 for ports 5 and 6, the choice 7 for port

FIRMWARE VERSION 1.0.14.1 GXW400X USER MANUAL Page 22 of 60

8 is required to indicate that the SIP account tied to port marked as “Active” will be used for all members

of the same Hunting group. Needless to say, those members of the same Hunting group may not be

sequential ports. In following example ports 3, 5 and 7 tied to SIP Account configured in Port #1 marked

as “Active”, and ports 4,6,8 tied to SIP Account configured in Port #2 marked as “Active” as well.

Example of not sequential configuration of a multiple Hunting Group:

FXS Port #1: SIP UserID and Authenticate ID entered, Hunting group set to "Active"

FXS Port #2: SIP UserID and Authenticate ID entered, Hunting Group set to "Active"

FXS Port #3: SIP UserID and Authenticate ID left blank, Hunting Group set to "1"

FXS Port #4: SIP UserID and Authenticate ID left blank, Hunting group set to "2"

FXS Port #5: SIP UserID and Authenticate ID left blank, Hunting Group set to "1"

FXS Port #6: SIP UserID and Authenticate ID left blank, Hunting Group set to "2"

FXS Port #7: SIP UserID and Authenticate ID left blank, Hunting group set to "1"

FXS Port #8: SIP UserID and Authenticate ID left blank, Hunting Group set to "2"

Note: A single call directed to the SIP account will NOT result in all ports ringing at the same time. They

will ring in the hunting group only. This feature is applicable to incoming calls only.

There are two types of hunting groups, Linear and Circular. Linear style will sort the call to the lowest-

numbered available line, this is also called “serial hunting”. Circular style will distribute the calls "round-

robin". If a call is assigned to line 1, the next call goes to 2 and the next to 3. The succession throughout

each of the lines continues even if one of the previous lines becomes available. When the end of the hunt

group is reached, the hunting starts over at the first line. Lines are skipped if they are still busy on a

previous call. These two hunting styles can be configured from the Profile_x page.

INTER-PORT CALLING

In some cases a user may want to make phone calls between the phones connected to multiple ports of

the same gateway when it is used as a stand alone unit, without the use of a SIP server. This feature will

also be applicable when the gateway is used with Hunting Groups and is registered to SIP server only

with one master number. In such cases users still will be able to make inter-port calls by using the IVR

feature.

For example on the GX4004 and GXW4008 the user connected to port 1 can reach the user connected to

port 3 by dialing *** and 73. Digit 7 indicated using inter-port calling feature, digit 3 indicates the port

number which should be reached. At the same manner the user connected to port 4 can reach the user

connected to port 8 by dialing *** and 78.

FIRMWARE VERSION 1.0.14.1 GXW400X USER MANUAL Page 23 of 60

PSTN PASS THROUGH/LIFE LINE

The RJ-11 line jack on the GXW400X side connected to a legacy PSTN line, functions as a pass through

jack when the GXW400X loses power or becomes unregistered. In this case, analog phone connected to

FXS port 1 will be directly connected to RJ-11 jack marked as LINE. The pass through/life line mode

enables the user to use the analog phone for PSTN calls directly without using an access code.

SENDING AND RECEIVING FAX

GXW400X supports fax in two modes: 1) T.38 (Fax over IP) and 2) Fax Pass through. T.38 is the

preferred method because it is more reliable and works well in most network conditions. If the service

provider supports T.38, please use this method by selecting T.38 as fax mode (default). If the service

provider does not support T.38, pass-through mode may be used. If you have problems with sending or

receiving Fax, toggle the Fax Tone Detection Mode setting.

SUPPORT RADIUS PROTOCOL

GXW400X supports RADIUS for authentication, authorization and billing purposes. Primary and

secondary RADIUS server configurations are available to provide redundancy to this feature. In case

Primary Radius server becomes unusable, RADIUS requests will be automatically sent to the secondary

server. When at least one RADUIS server was configured, the device will allow users to make phone calls

only after authorization from RADIUS server has been received. CDR (Call Detail Record) is also sent to

the RADIUS server for billing purposes. RAIDUS server can send requests to terminate calls when run

out of pre-paid credit.

The GXW400X will be able to work in VoIP billing environment using redundant double server

configuration. User will be able to configure primary and secondary RADUIS server IP Addresses or

FQDNs. Once at least one RADUIS server was configured, the device will allow users to make phone

calls only after permission from RADIUS server has been received. In case Primary Radius server

becomes unusable, secondary will take role of primary and will manage credit recourses in the network.

Imbedded RADIUS client also supports request generated by Radius server to terminate calls when run out of

pre-paid credit.

ACCESS THE WEB CONFIGURATION MENU

The GXW400X HTML configuration menu can be accessed via LAN or WAN port:

From the LAN port (For GXW4004/8 only)::

1. Directly connect a computer to the LAN port.

2. In Windows, open a ‘Command Prompt’ window

3. Type in “ipconfig /release”, the IP address etc. becomes 0.

4. Type in “ipconfig /renew”, the computer gets an IP address in 192.168.2.x segment by default

5. Open a web browser, type in the default gateway IP address. http://192.168.2.1. You will see the

From the WAN port (For GXW4004/8 only):

The WAN port HTML configuration option is disabled by default from factory. To access the HTML

configuration menu from the WAN port:

1. Follow table 4 to find the WAN side IP address.

2. Open a web browser, type in the WAN side IP address – for example: http://GXW400X -IP-

Address (the GXW400X IP-Address is the WAN IP address for the GXW400X).

NOTE:

 WAN side HTTP access is disabled by default for security reasons. You can enable HTTP access on

the configuration page by setting “WAN side HTTP access” to be YES.

 Initial access to the configuration pages is always from the LAN port. The instructions are listed above.

 The IVR announces 12 digits IP address, you need to strip out the leading “0” in the IP address. For ex.

IP address: 192.168.001.014, you need to type in http://192.168.1.14 in the web browser.

Once the HTTP request is entered and sent from a web browser, the user will see a log-in screen. There are

two default passwords for the login page:

IMPORTANT SETTINGS

The end-user must configure the following settings according to the local environment.

NOTE: Most settings on the web configuration pages are set to the default values.

NAT SETTINGS

If you plan to keep the gateway within a private network behind a firewall, we recommend using STUN

Server. The following three (3) settings are useful in the STUN Server scenario:

1. STUN Server (under Advanced Settings webpage)

Enter a STUN Server IP (or FQDN) that you may have, or look up a free public STUN Server on the

internet and enter it on this field. If using Public IP, keep this field blank.

2. Use Random Ports (under Advanced Settings webpage)

It really depends on your network settings, so set this parameter to Yes or No, whichever works.

Generally if you have multiple IP devices under the same network, it should be set to Yes. If using a

Public IP address, set this parameter to No.

3. NAT Traversal (under the Profile web pages)

Set this to Yes when gateway is behind firewall on a private network.

DTMF METHODS

DTMF Settings are in Profile pages.

 DTMF in-audio

 DTMF via RTP (RFC2833)

 DTMF via SIP INFO

You can enable set priority of DTMF methods according to your preference, from Priority 1 to 3. This

setting should be based on your server DTMF setting.

PREFERRED VOCODER (CODEC)

The GXW400X supports a broad range of voice codecs. Under Profile web pages, choose your preferred

order of different codecs:

 PCMU/A (or G711µ/a)

 G729 A/B/E

 G723
