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 HT–502 and other VoIP Device, have public IP addresses, or 2. Both HT–502 and other VoIP Device are on the same LAN using private IP addresses, or 3.
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 confirm tone. Then, A can hang up. NOTE: “Enable Call Feature” must be set to “Yes” in web configuration page. Caller A can place a call on hold and wait for one of three situations: 1.
Call Features The HT–502 supports all the traditional and advanced telephony features. TABLE 6: HT–502 CALL FEATURE DEFINITIONS Key *30 *31 *47 *50 *51 *67 *82 Call Features Block Caller ID (for all subsequent calls) Send Caller ID (for all subsequent calls) Direct IP Calling. Dial “*47” + “IP address”. No dial tone is played in the middle. Detail see Direct IP Calling section on page 12.
SENDING AND RECEIVING FAX HT–502 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.
CONFIGURING THE HT–502 USING THE WEB BROWSER HT–502 has an embedded Web server that will respond to HTTP GET/POST requests. It also has embedded HTML pages that allow users to configure the HT–502 through a web browser such as Microsoft’s IE and AOL’s Netscape.

TABLE 8: HT–502 DEVICE STATUS PAGE DEFINITIONS MAC Address The device ID in HEX format. This is needed for ISP troubleshooting. Note there are separate MAC addresses for the WAN side and the LAN side. WAN IP Address Shows WAN IP address of HT–502. Product Model Contains the product model info. Software Version Program: This is the main software release. Boot and Loader are seldom changed. System Up Time Shows system up time since the last reboot.
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. Default setting is blank. STUN Server IP address or Domain name of the STUN server. Keep-alive interval This parameter specifies how often the HT–502 sends a blank UDP packet to the SIP server in order to keep the “hole” on the NAT open. Default is 20 seconds. Minimum value is 20 seconds.
Firmware Key Used for firmware encryption. Should be 32 digit in hexadecimal representation. End user should keep it blank. Authenticate Conf File If set to Yes, config file is authenticated before acceptance. This protects the configuration from an unauthorized change. Firmware Key Used for firmware encryption. Should be 32 digit in hexadecimal representation. End user should keep it blank. Lock Keypad Update If set to “Yes”, the configuration update via keypad is disabled.
work and ONLY outbound proxy can correct the problem. SIP transport NAT Traversal (STUN) User can select UDP or TCP or TLS. This parameter defines whether or not the HT–502 NAT traversal mechanism is activated. If activated (by choosing “Yes”) and a STUN server is also specified, then the HT–502 performs according to the STUN client specification. Using this mode, the embedded STUN client will detect if and what type of firewall/NAT is being used.
Refer to Use Target Contact Default is NO. If set to YES, then for Attended Transfer, the “Refer-To” header uses the transferred target’s Contact header information. DTMF Payload Type DTMF in-audio DTMF via RFC2833 DTMF via SIP INFO Sets the payload type for DTMF using RFC2833. Send DTMF as inband (in-audio). Send DTMF via RTP (According to RFC 2833).

CONFIGURATION THROUGH A CENTRAL SERVER Grandstream HT-502 can be automatically configured from a central provisioning system. When HT-502 boot up, it will send TFTP or HTTP request to download configuration file, “cfg000b82xxxxxx”, where “000b82xxxxxx” is the LAN side MAC address of the HT-502 Download the configuration files via TFTP or HTTP from the central server.
SOFTWARE UPGRADE Software upgrade can be done via either TFTP or HTTP. The corresponding configuration settings are in the ADVANCED SETTINGS configuration page. FIRMWARE UPGRADE THROUGH TFTP/HTTP To upgrade via TFTP or HTTP, the “Firmware Upgrade and Provisioning upgrade via” field needs to be set to TFTP or HTTP, respectively. “Firmware Server Path” needs to be set to a valid URL of a TFTP or HTTP server, server name can be in either FQDN or IP address format. Here are examples of some valid URL. e.g.
CONFIGURATION FILE DOWNLOAD Grandstream SIP Device 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 configuration file. It needs to be set to a valid URL, either in FQDN or IP address format. The “Config Server Path” can be same or different from the “Firmware Server Path”. A configuration parameter is associated with each particular field in the web configuration page.

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 (eight-bit 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.
