ERIES OVERVIEW

Currently, the GXV300x IP Video Phone series consists of the following three models: GXP3000, GXV3005 and GXV3006.

The GXV300x series is a next generation IP video phone based on SIP standard and H.264 video codec, the codec of choice for high-quality video. It also supports H.263/H.263+ legacy video codec just for compatibility. The GXV300x supports real-time (up to 30fps) high-quality video at very modest bandwidth level (as low as 32kbps, up to 1Mbps). The phone allows nearly all viewing angles via a large 5.6” TFTP adjustable LCD screen and a VGA camera, creating high-quality videoconferences from your desk.

The GXV300x combines great design and technology with excellent audio and picture quality, ease of use and broad interoperability with 3rd party SIP products. It is ideal for any multi-media communication environment, the virtual office and all IP video communications for business or residential users.

ULTIPLE

The GXV300x can support up to 3 independent SIP accounts. Each account is capable of independent SIP server, user and NAT settings. Each of the 3 line buttons (LINE1-LINE3) is “virtually” mapped to an individual SIP account. In off-hook state, select an idle line and the name of the account (as configured in the web interface) is displayed on the LCD and a dial tone is heard. Or, press the selected line continuously until the related SIP profile showed up on the LCD.

For example: Configure the three SIP accounts as “FreeWorldDialup”, “BroadSoft” and “Asterisk PBX” respectively and ensure each is active and registered. When LINE1 is pressed, you will hear a dial tone and see “FreeWorldDialup” on the LCD display; when LINE2 is pressed, you will hear a dial tone and see “BroadSoft” on the LCD display; when LINE3 is pressed, you will hear a dial tone and see “Asterisk PBX” on the LCD display. Or press LINE1 twice you will hear dial tone and see “BroadSoft” also.

To make a call, select the line you wish to use. The LED will light up solid red. If you continue to press one LINE, it will circulate among the registered accounts.

For example: when LINE1 is pressed, the LCD displays “FreeWorldDialup”; If LINE1 is pressed twice, the LCD displays “BroadSoft” and the subsequent call will be made through SIP account 2 - BroadSoft.

Incoming calls to a specific account will attempt to use its corresponding LINE if it is not in use. When the “virtually” mapped line is in use, the GXV300x will flash the next available LINE (from left to right) in

red. A line is ACTIVE when it is in use and the corresponding LED is solid red.

lected.

• The phone waits 4 seconds (by default; no key entry timeout) before sending and initiating the call. Press the “SEND” button (or # key if configured) to override the 4 second delay.

Making Calls using IP Addresses

Direct IP calling allows two phones to talk to each other in an ad hoc fashion without a SIP proxy. VoIP calls can be made between two phones if:

• Both phones have public IP addresses, or

• Both phones are on a same LAN/VPN using private or public IP addresses, or

Grandstream Networks, Inc. GXV300x User Manual Page 13 of 54 Firmware 1.2.3.7 Updated: 12/2010

Page 16

• Both phones can be connected through a router using public or private IP addresses (with neces- sary port forwarding or DMZ)

To make a direct IP call, please follow these steps:

1. Press MENU button to bring up MAIN MENU.

2. Select “Direct IP Call” using the arrow-keys.

3. Press OK to select.

4. Input the 12-digits target IP address. (Please see example below).

5. Press OK key to initiate call.

For example: If the target IP address is 192.168.1.60 and the port is 5062 (e.g. 192.168.1.60:5062), input the following: 192*168*1*60#5062 - “ * ” key represent “.” and “#” key represent “:”. Press OK to dial out.

Quick IP Call Mode

Dial an IP address under the same LAN/VPN by keying in the last octet in the IP address. This partially simulates a PBX function using the CMSA/CD without a SIP server. Static IP usage recommended.

In the “Advanced Settings” page, set the "Use Quick IP-call mode” to “YES”. When #xxx# is dialed, where x is 0-9 and xxx <=255, a direct IP call to aaa.bbb.ccc.XXX is completed. “aaa.bbb.ccc” is from the local IP address regardless of subnet mask.

#xx or #x are also valid. The leading 0 is not required (but OK).

For example:

• 192.168.0.2 calling 192.168.0.3 -- dial #3 follow by SEND or #

• 192.168.0.2 calling 192.168.0.23 -- dial #23 follow by SEND or #

• 192.168.0.2 calling 192.168.0.123 -- dial #123 follow by SEND or #

• 192.168.0.2: dial #3 and #03 and #003 results in the same call -- call 192.168.0.3

NOTE: If you have a SIP Server configured (not recommended for IP calling), a Direct IP-IP still works. If you are using STUN, the Direct IP-IP call will also use STUN. Configure the “Use Random Port” to “NO” when completing Direct IP calls.

The GXV3006 is based on the same high performance feature set as the GXV3000. The additional Phone/FXS port allow making/answering call by using analog phone.

Making calls

Making call using analog phone through different lines can be done in two different ways.

- Pressing LINEx button on GXV3006 main case. Then, dial destination number on analog phone. Or

- Dial *x* on analog phone to get second dial tone. Then, dial the destination number. Note: “x” represents the line which will be used to make calls. For example: Dialing *3* on analog phone will get the second dial tone. Then, dial the destination number.

Receiving calls

When receiving calls, not only GXV3006 main phone would ring but also the analog phone. Picking up the handset of analog phone will also answer the call. After the call is answered, audio can be heard on both GXV3006 and the analog phone by picking up handset. Video can be seen on GXV3006 no matter the call is answered by GXV3006 or the analog phone.

stead of

Date

• DHCP mode: all the field values for the Static IP mode are not used (even though they are still saved in the Flash memory.) The GXV300x acquires its IP address from the first DHCP server it discovers on its LAN. The DHCP option is reserved for NAT router mode (currently NOT implemented).

• To use the PPPoE feature, set the PPPoE account settings. The GXV300x estab- lishes a PPPoE session if any of the PPPoE fields is set.

• Preferred DNS Server: If configured and enabled, all the DNS query will be sent to this server instead of other DNS servers from network.

• Static IP mode: configure all of the following fields: IP address, Subnet Mask, De- fault Router IP address, DNS Server 1 (primary), DNS Server 2 (secondary).

This parameter controls the date/time display according to the specified time zone. The “Allow DHCP Option 2 to override Time Zone setting” option allows DHCP server to override default NTP time server if user has own NTP server. Default is No.

This parameter controls time displayed in daylight savings time. If set to “Yes”, then the displayed time will be 1 hour ahead of normal time.

The “Optional Rule” is configured to automatically adjust the Daylight Savings Time (DST) based on the rule set in this field. Rule Syntax:

• start-time; end-time; saving

• Both start-time and end-time have the same syntax: month,day,weekday,hour,minutes

o month: 1,2,3,..,12 (for Jan, Feb, .., Dec) o day: [+|-]1,2,3,..,31 o weekday: 1, 2, 3, .., 7 (for Mon, Tue, .., Sun), or 0 which means the daylight

saving rule is not based on week days but based on the day of the month.

o hour: hour (0-23), minute: minute (0-59)

If “weekday” is 0, it means the date to start or end daylight saving is at exactly the given date. In that case, the “day” value must not be negative. If “weekday” is not zero and “day” is positive, then the daylight saving starts on the first “day” the iteration of the weekday (e.g.: 1st Sunday, 3rd Tuesday etc). If “weekday” is not zero and “day” is negative, then the daylight saving starts on the last “day” the iteration of the weekday (e.g.: last Sunday, 3rd last Tuesday etc).

The saving is in the unit of minutes. The saving time may also be preceded by a negative (-) sign if subtraction is desired instead of addition.

The default value is set for US, the “Automatic Daylight Saving Time Rule” shall be set to

“3,2,7,2,0;11,1,7,2,0;60”

Examples US/Canada where daylight saving time is applicable:

03,02,7,02,00;11,1,7,02,00;60 This means the daylight saving time starts from the second Sunday of March at 2AM and ends the first Sunday of November at 2AM. The saving is 60 minutes.

Suppression

per TX

This controls the silence suppression/VAD feature of the audio codec G.723 and G.729. If set to “Yes”, when silence is detected, a small quantity of VAD packets (instead of audio packets) will be sent during the period of no talking.

This field contains the number of voice frames to be transmitted in a single Ethernet packet (be advised the limit is based on the maximum size of Ethernet packet which is 1500 byte or 12kbps).

When setting this value, be aware the requested packet time (ptime, used in SDP message) is a result of configuring this parameter. This parameter is associated with the first codec in the above codec Preference List or the actual used payload type negotiated between the 2 conversation parties at run time. e.g., if the first codec is configured as G.723 and the “Voice Frames per TX” is set to 2, then the “ptime” value in the SDP message of an INVITE request will be 60ms because each G.723 voice frame contains 30ms of audio. Similarly, if this field is set to 2 and the first codec is G.729 or G.711 or G.726, then the “ptime” value in the SDP message of an INVITE request will be 20ms.

If the configured voice frames per TX exceeds the maximum allowed value, the IP phone will use and save the maximum allowed value for the corresponding first codec choice. The maximum value for PCM is 10 (x10ms) frames; for G.726, it is 20 (x10ms) frames; for G.723, it is 32 (x30ms) frames; for G.729/G.728, 64 (x10ms) and 64 (x2.5ms) frames respectively.

Please be careful when editing these parameters. Adjusting these parameters will also change the jitter buffer. The GXV300x has a patent jitter buffer handling algorithm.

Grandstream recommends using the default settings and not adjusting these parameters. Incorrect settings will affect the voice quality.

Default value is 15 frames/second. The video frame rate is adjustable based on network conditions. Increasing the frame rate will increase the amount of data significantly therefore con-

Default is No. If set to “Yes”, the configuration changes via keypad are disabled. Caution:

Phone could get LOCKED if user configured this option but forgot administration password or WebUI access broken.

User can choose another display language on LCD and the phone’s web UI. Language file postfix allows the language file to have different postfixes so the phone can request a particular file. It will append an underscore "_" plus the string in the language file postfix.

The default language file name is "gxv.lpf". If the field “Language File postfix “has "NL" string in it, then the phone will request "gxv_NL.lpf" instead of "gxv.lpf."

Supported language: Catalan, Czech, Dutch, Estonian, Finnish, French, German, Italian, Po Portuguese, Slovak, Slovenian, Spanish, Swedish and Turkish.

How to set up Secondary Language:

1. Download the language package from http://www.grandstream.com/firmware.html

This field indicates whether the account is active. The default value for the primary account

The name associated with each account - displayed on LCD. SIP Server’s IP address or Domain name provided by VoIP service provider. IP address or Domain name of Outbound Proxy or Session Border Controller.

Used by GXV300x for firewall or NAT penetration in different network environment. If it detects symmetric NAT, STUN will not work. ONLY OBP or session border controller can provide solution for symmetric NAT.

User account information provided by VoIP service provider (ITSP). It is either an actual phone number or something formatted like one.

SIP service subscriber’s Authenticate ID used for authentication. It can be identical to or different from SIP User ID.

SIP service subscriber’s account password for GXV300x to register to (SIP) server. SIP service subscriber’s name that is used for Caller ID display. Default is No.

If set to “Yes”, phone will use “Preferred DNS SRV” (Basic Setting Page) to look up server. If the GXV300x has an assigned PSTN telephone number, this field should be set to “Yes”.

Otherwise, set it to “No”. If “Yes” is set, a “user=phone” parameter will be attached to the “From” header in SIP request to indicate the E.164 number

This parameter controls whether the GXV300x needs to send REGISTER messages to the proxy/server. The default setting is “Yes”.

choosing “Yes”) and a STUN server is also specified, then the GXV300x will behave according to the STUN client specification. Using this mode, the embedded STUN client detects what type of NAT/Firewall router used and displayed the result in Status Page.

If the detected NAT is a Full Cone, Restricted Cone, or a Port-Restricted Cone, the GXV300x will attempt to use its mapped public IP address and port in all of its SIP and SDP messages.

If the NAT Traversal field is set to “No, but send keep-alive” with no specified STUN server, the GXV300x will periodically (every 20 seconds or so) send a blank UDP packet (with no payload data) to the SIP server to keep the “hole” on the NAT router open.

If the detected NAT is symmetric NAT, then STUN can NOT be used and an Outbound Proxy or Session Border Controller must be used and this field must be configured to “NO”.

Default is No

Default is No. When set to “Yes” a SUBSCRIBE for Message Waiting Indication will be sent periodically. GXV300x supports both synchronized and non-synchronized MWI.

SIP Extension to notify SIP server that the unit is behind the NAT/Firewall.

Default is No. If set to Yes, the header is sent in compact format. This is helpful in stateless proxy with multiple codec used as big UDP packet is not router friendly during transit.

When configured, user can access VM messages by pressing “MSG” button. This ID is usually the VM portal access number, e.g.: 8500 in Asterisk or 8502 for FWD.

This parameter specifies the mechanism to transmit DTMF digit. There are 3 supported modes: in audio which means DTMF is combined in audio signal (not very reliable with low-bit-rate codec), via RTP (RFC2833), or via SIP INFO.

Default is No. Use only if proxy or server supports 484 response.

boot up, it will send TFTP or HTTP request to download configuration file,

GXV300x

The configuration file can be downloaded via TFTP or HTTP/HTTPS from the central server. A service provider or an enterprise with large deployment of

GXV300x

can easily manage the configuration and ser-

vice provisioning of individual devices remotely from a central server. Grandstream has a provisioning system called GAPS (Grandstream Automated Provisioning System) that

is used to support automated configuration of Grandstream devices. GAPS uses enhanced (NAT friendly) TFTP or HTTP (thus no NAT issues) and other communication protocols to communicate with each individual Grandstream device for firmware upgrade, remote reboot, etc.

Grandstream provides GAPS service to VoIP service providers. Use GAPS for either simple redirection or with certain special provisioning settings. At boot-up, Grandstream devices by default point to Grandstream provisioning server GAPS, based on the unique MAC address of each device, GAPS provision the devices with redirection settings so that they will be redirected to customer’s TFTP or HTTP/HTTPS server for further provisioning. Grandstream also provide GAPSLITE software package which contains our NAT friendly TFTP server and a configuration tool to facilitate the task of generating device configuration files.

The GAPSLITE configuration tool is now free to end users. The tool and configuration template are available for download from http://www.grandstream.com/support/configurationtool.html .

OFTWARE UPGRADE & CUSTOMIZATION

Software (or firmware) can be upgraded using either TFTP or HTTP. The corresponding configuration settings are in the ADVANCED SETTINGS configuration page.

IRMWARE UPGRADE THROUGH

To upgrade via TFTP or HTTP, select TFTP or HTTP upgrade method. “Firmware Server Path” needs to be set to a valid IP or URL of a HTTP or TFTP server. Server name can be in either FQDN or IP address format. Here are examples of some valid URLs.

• firmware.mycompany.com:6688/Grandstream/1.2.3.7

• 72.172.83.110

There are two ways to set up the Upgrade Server to upgrade firmware: Key Pad Menu and Web Configuration Interface.

TFTP/HTTP

Key Pad Menu

To configure the Upgrade Server via Key Pad Menu options, select “Config” from the Main Menu, then select “Upgrade”. Under this sub Menu, user can edit Upgrade Server in either an IP address format or FQDN format. Choose “Save and use TFTP” or “Save and use HTTP” to select upgrade method. Select “Reboot” from the Main Menu to reboot the phone.

Web Configuration Interface

To configure the Upgrade Server via the Web configuration interface, open the web browser. Enter the

GXV300x

ADVANCED SETTINGS page, enter the Upgrade Server’s IP address or FQDN in the “Firmware Server Path” field. Select TFTP or HTTP upgrade method. Update the change by clicking the “Update” button. “Reboot” or power cycle the phone to update the new firmware.

During this stage, the LCD will display the firmware file downloading process and flashing process. Please do NOT interrupt this process and make sure NO power outage at this stage.

If a firmware upgrade fails for any reason, the phone will stop the upgrading process and re-boot using the existing firmware.

NOTE: If the phone cannot boot up, user can force the phone to load the internal stored booting code by pressing the “#” and “*” key simultaneously and power on the phone. Then flash the phone again using the correct firmware files.

Firmware upgrades may take 5 minutes in a controlled LAN environment or up to 45 minutes over the public Internet. Grandstream recommends download firmware file and complete firmware upgrade process in a controlled LAN environment whenever possible.

IP address. Enter the administrator password to access the web configuration interface. In the

No Local HTTP/TFTP Server

For users who do not have a local TFTP/HTTP server, Grandstream provides a HTTP server on the public Internet for users to download the latest firmware upgrade automatically. Please check the Support/Download section of our website to obtain this HTTP server IP address:

http://www.grandstream.com/firmware.html

Grandstream Networks, Inc. GXV300x User Manual Page 40 of 54 Firmware 1.2.3.7 Updated: 12/2010

Page 43

Alternatively, download and install a free TFTP or HTTP server and perform firmware upgrades. Free Windows version TFTP server is available: http://support.solarwinds.net/updates/New-customerFree.cfm. Or http://tftpd32.jounin.net/.

Instructions for firmware upgrade via a Local TFTP Server:

1. Unzip the file and put all of them under the root directory of the TFTP server.

2. The PC running the TFTP server software and the

GXV300x

should be in the same

LAN segment.

3. Make sure the firmware files are in the correct root folder of TFTP server. If using Solarwinds free TFTP server, make sure changing the TFTP server's default setting from "Receive Only" to "Transmit Only" for the firmware upgrade. Then start the server by running the TFTP server software.

4. In the phone’s web configuration page, configure the Firmware Server Path to the IP address of the PC running the TFTP software.

5. Update the change and reboot the phone.

NOTE: Make sure to set “Allow DHCP Option 66 to override server” to NO, otherwise, If DHCP option

66 turned ON in LAN, the TFTP server can be redirected. You can also download the free HTTP server from

HTU

http://httpd.apache.org/UT or use Microsoft IIS web

server embedded in some version of Windows OS.

NOTE: When “cfg000b82xxxxxx”, where “000b82xxxxxx” is the MAC address of the

GXV300x

phone boots up, it will send TFTP or HTTP request to download configuration file

GXV300x

phone. This file is for ini- tial provisioning purpose only. For normal TFTP or HTTP firmware upgrades, the following error messages in a TFTP or HTTP server log can be ignored: “TFTP Error from [IP ADRESS] requesting cfg000b82023dd4 : File does not exist. Configuration File Download”.

ONFIGURATION FILE DOWNLOAD

The

GXV300x

can be configured via Web Interface as well as via Configuration File through TFTP or HTTP. “Config Server Path” is the TFTP or HTTP server path for the configuration file. It needs to be set to a valid URL, either in FQDN or IP address format.

The configuration parameter is associated with each particular field in the web configuration page. A parameter consists of a capital letter P and 2 or 3 (could be extended to 4 in the future) digit numeric numbers. i.e., P2 is associated with “Admin Password” in the ADVANCED SETTINGS page. For a detailed parameter list, please refer to the corresponding configuration template of the firmware.

Once the

GXV300x

boots up (or re-booted), it will request a binary configuration file named “cfgxxxxxxxxxxxx”, where “xxxxxxxxxxxx” is the MAC address of the device, i.e., “cfg000b820102ab”. The configuration file name should be in lower cases.

NOTE: For earlier hardware versions (prior to V1.1), a manual power cycle is required if the LCD is pale or changes to the color white after firmware upgrade or configuration file downloading. For hardware versions after V1.1, the

GXV300x

automatically reboots itself after such process.

If the firmware crashes for an unknown reason during upgrade and the phone cannot boot up, please press “#” and “*” keys simultaneously then power up the phone. This will force the phone to load the stored boot file so that user can flash the phone again with good firmware files.

NOTE: Make sure to set “Allow DHCP Option 66 to override server” to NO, otherwise, If DHCP option

66 turned ON in LAN, the TFTP server can be redirected.

ANAGING FIRMWARE AND CONFIGURATION FILE DOWNLOAD

When “Automatic Upgrade” is set to “Yes”, Service Provider can use P193 (Auto Check Interval, in minutes, default and minimum is 60 minutes) to have the device periodically checked for upgrades at prescheduled time intervals. By defining different intervals in P193 for different devices, a Server Provider can manage and balance the Firmware or Provisioning Server load at any given time.

GXV C

XML P

USTOMIZATION

HONEBOOK

Introduction

The Grandstream GXV enables you to easily share and maintain a phonebook through the web. The XMLphonebook must be stored on a web-server. There are also applications where organizations wish to be able to have a centralized directory server and have all phones in the organization to sync up with the server periodically.

How It Works and Configuration

A new set of configuration options will be introduced as following:

 Enable Downloadable Phonebook (P330): NO/YES-HTTP/YES-TFTP (default NO). Possible

values 0 (NO)/1 (HTTP)/2 (TFTP), other values ignored.

 Phonebook XML Path (P331): This is a string of up to 128 characters that should contain a

path to the XML file. It MUST be in the host/path format. For example: “directory.grandstream.com/engineering”

 Remove manually edited entries on download (P333): YES/NO (default NO), possible values

0 (NO)/1 (YES), other values ignored

The feature will be activated when “Enable Downloadable Phonebook” is set to YES (HTTP or TFTP) AND a valid “Phonebook XML Path” is set.

When the device boots up and completed the provisioning routine, it will attempt to download the gs_phonebook.xml file specified in “Phonebook XML Path” and process it as described in the next chapter. Please note that the phonebook file name is fixed, so you can not alter the phonebook file name based on your preference. During this process the LCD should display some messages to indicate that XML Phonebook download is in progress.

When the XML file is downloaded, GXV300x will parse it and extract the entries from it. If the “Remove manually edited entries on download” option is set to No (by default), the device will keep ALL stored entries manually edited before, and insert the downloaded entries, and then save the phonebook. Otherwise ALL the existing phonebook entries on the phone will be erased and filled with the downloaded entries.

At any time, you can trigger an immediate download from by choosing the “Download Phonebook” in the GUI Phone Book Menu.

CREENSAVER IMAGES

Customize the screensaver images by using the free “Screensaver Generation Tool” downloadable from

http://www.grandstream.com/support/gxv_series_phone/gxv300x/gxv300x_support.html under “Firmware

& Downloads” tab Personalize the screensaver by downloading your favorite pictures. Picture requirements:

• Baseline JPEG

• 320x240 in dimension

• RGB color space

• 8-bit data

The screensaver file (image.bin, cannot rename this file) is limited to 20 images or 320kb, whichever limit is reached first. Screensaver pictures, as well as the customized ring tones, are flashed into the phone the same way to upgrade firmware. Just put the files together with firmware files.

Grandstream recommends that you resize pictures using popular photo processing software. The following screen shots are resize pictures using Adobe Photoshop:

IGURE 6: SIZING THE SCREENSAVER

NOTE: Picture MUST be preprocessed and resized to 320 x 240 and picture must be saved in Baseline

JPEG format. Otherwise it will not be shown in the LCD screen of the phone.

USTOMIZED RING TONES

Download the free Ringtones Generation tool from http://www.grandstream.com/support/downloads.html Please follow the same rules as above

HTU

Screensaver Images

UTH

to generate the ringtone files and load them

into the phone.

Ringtone File Size

File requirements for ring tone conversion:

1. Must be either .wav or .mp3 format [recommend .wav format]

2. Converted file size must be less than 64KB other wise it will override next file slot space.

3. Flash only has space to store 3 ringtone files (64KB x 3 = 192KB total space)

The ring tone generator supports 16-bit linear PCM as input (not PCMU or PCMA). If a ring tone file is larger than 64KB, it will occupy the next available ring tone file slot. For example: If

the 2nd ringtone file size is more than 64KB (but less than 128KB), the 3rd “ring3.bin” will not have enough storage space and it will not be able to load into the phone.

The ringtone files must follow the following naming convention: “ring1.bin”, “ring2.bin”, and “ring3.bin”. Ringtone files can not be renamed.
