BASIC OPERATIONS UNDERSTANDING GXW VOICE PROMPTS GXW–400x has a stored voice prompt menu for quick browsing and simple configuration. Enter *** on the standard analog phone connected to any FXS port to use the voice prompt menu.
Five Success Tips when using the Voice Prompt 1. “*” shifts down to the next menu option 2. “#” returns to the main menu 3. “9” functions as the ENTER key in many cases to confirm an option 4. All entered digit sequences have known lengths - 2 digits for menu option and 12 digits for IP address. For IP address, add 0 before the digits if the digits are less than 3 (i.e. - 192.168.0.26 should be key in like 192168000026. No decimal is needed). 5.
EXAMPLES OF DIRECT IP CALLS: 1. If the target IP address is 192.168.0.10, the dialing convention is: Voice Prompt with option 47, then 192 168 000 010 followed by the “#” key or wait 4 seconds. 2. If the target IP address/port is 192.168.1.20:5062, then the dialing convention is: Voice Prompt with option 47, then 192168001020*45062 followed by the “#” key or wait 4 seconds. CALL HOLD Place a call on hold by pressing the “flash” button on the analog phone (if the phone has that button).
3-WAY CONFERENCING Star Code Style 3-way Conference Caller A wants to bring third Caller C into conference: 1. Caller A presses FLASH to receive a dial tone. (Hook Flash for older model phones) 2. Caller A dials Caller C’s number then # (or wait for 4 seconds). 3. If Caller C answers call, then Caller A presses “flash” to bring Parties B & C into conference. 4. If Caller C does not answer the call, Caller A can press “flash” to resume call with Caller B.
CALL FEATURES The GXW–400x supports traditional and advanced telephony features. These features are easy to use with any phone.

Web Port By default, HTTP uses port 80. This field is for customizable web port. IP Address There are two modes to operate the GXW–400x: DHCP mode: all the field values for the Static IP mode are not used (even though they are still saved in the Flash memory.
TABLE 8: STATUS PAGE DEFINITIONS MAC Address The device ID in HEX format. This is needed for ISP troubleshooting. WAN IP Address Shows LAN IP address of GXW–400x Product Model Contains the product model info. Software Version Program: This is the main software release. Boot and Loader are not changed often. System Up Time Shows system up time since the last reboot. PPPoE Link Up Shows whether the PPPoE connection is running if connected to DSL modem.

Password field is purposely left blank for security reasons after clicking update and saved. The maximum password length is 25 characters. Layer 3 QoS This field defines the layer 3 QoS parameter which can be the value used for IP Precedence or Diff-Serv or MPLS. Default value is 48. Layer 2 QoS Value used for layer 2 VLAN tag.
Syslog Server The IP address or URL of System log server. This feature is especially useful for the ITSP (Internet Telephone Service Provider) Syslog Level Select the GXW–400x to report the log level. Default is NONE. The level is one of DEBUG, INFO, WARNING or ERROR. Syslog messages are sent based on the following events: 1. product model/version on boot up (INFO level) 2. NAT related info (INFO level) 3. sent or received SIP message (DEBUG level) 4. SIP message summary (INFO level) 5.
TABLE 11: PROFILE PAGE DEFINITIONS Profile Active When set to Yes the SIP Profile is activated. SIP Server SIP Server’s IP address or Domain name provided by VoIP service provider. Outbound Proxy IP address or Domain name of Outbound Proxy, or Media Gateway, or Session Border Controller. Used by GXW–400x for firewall or NAT penetration in different network environments. If symmetric NAT is detected, STUN will not work and ONLY outbound proxy can correct the problem.
DTMF Payload Type Sets the payload type for DTMF using RFC2833. DTMF in-audio Send DTMF as inband (in-audio). DTMF via RTP Send DTMF via RTP (According to RFC 2833). DTMF via SIP INFO Send DTMF via SIP INFO message. Send Flash Event Default is NO. If set to yes, flash will be sent as DTMF event. Enable Call Features Default is No.
Use # as Dial Key Allows users to configure the “#” key as the “Send” (or “Dial”) key. If set to “Yes”, “#” will send the number. In this case, this key is essentially equivalent to the “(Re)Dial” key. If set to “No”, this “#” key can be included as part of number. Subscribe for MWI Default is No. When set to “Yes” a SUBSCRIBE for Message Waiting Indication will be sent periodically.
Polarity Reversal Default is No. If set to “Yes”, polarity will be reversed upon call establishment and termination. Hook Flash timing Gain Handset volume adjustment. RX is for receiving volume, TX is for transmission volume. Default values are 0dB for both parameters. Loudest volume: +6dB Lowest volume: -6dB. Call Progress/ Ring Tones Configure ring or tone frequencies according to preference. By default tones are set to North American frequencies.
FIRMWARE UPGRADE Our latest official release can be downloaded from: http://www.grandstream.com/y-firmware.htm. To upgrade your unit firmware, follow these steps: 1.

Go to File -> Configure -> Security to change the TFTP server's default setting from "Receive Only" to "Transmit Only" for the firmware upgrade. 4. Start the TFTP server, in the phone’s web configuration page. 5. Configure the Firmware Server Path with the IP address of the PC. 6.
GLOSSARY OF TERMS ADSL Asymmetric Digital Subscriber Line: Modems attached to twisted pair copper wiring that transmit from 1.5 Mbps to 9 Mbps downstream (to the subscriber) and from 16 kbps to 800 kbps upstream, depending on line distance. AGC Automatic Gain Control is an electronic system found in many types of devices. Its purpose is to control the gain of a system in order to maintain some measure of performance over a changing range of real world conditions.
FQDN Fully Qualified Domain Name. A FQDN consists of a host and domain name, including top-level domain. For example, www.grandstream.com is a fully qualified domain name. www is the host, Grandstream is the second-level domain, and and.com is the top level domain. FXS Foreign eXchange Office. An FXS device can be an analog phone, answering machine, fax, or anything that handles a call from the telephone company like AT&T. They should also operate the same way when connected to an FXS interface.
MTU A Maximum Transmission Unit (MTU) is the largest size packet or frame, specified in octets (eightbit bytes), that can be sent in a packet- or frame-based network such as the Internet. The maximum for Ethernet is 1500 byte. NAT Network Address Translation NTP Network Time Protocol, a protocol to exchange and synchronize time over networks The port used is UDP 123 Grandstream products using NTP to get time from Internet OBP/SBC Outbound Proxy or another name Session Border Controller.
UDP User Datagram Protocol (UDP) is one of the core protocols of the Internet protocol suite. Using UDP, programs on networked computers can send short messages known as datagrams to one another. UDP does not provide the reliability and ordering guarantees that TCP does; datagrams may arrive out of order or go missing without notice. However, as a result, UDP is faster and more efficient for many lightweight or time-sensitive purposes.
