Dial the number directly and press # (Use # as dial key must be configured in web configuration). Examples: 1. Dial an extension directly on the same proxy, (e.g. 1008), and then press the # or wait for 4 seconds. 2. Dial an outside 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.

Grandstream Networks, Inc. HT286 User Manual Firmware 1.1.0.31 Page 10 of 28 Last Updated: 1/2009
DIRECT IP CALLS Direct IP calling allows two parties with VoIP devices (e.g. a HT286and another VoIP Device), to talk to each other in an ad hoc fashion without a SIP proxy. Direct IP calls are possible if: a) Both VoIP devices use a public IP address; or b) Both VoIP devices are on the same LAN using private IP addresses, or c) Both VoIP devices can be connected through a router using public or private IP addresses (with necessary port forwarding or DMZ). To make a Direct IP Call, use either the handset or the speakerphone. Access the IVR using ***, the button on the HT286or 47. After dial tone, enter a 12-digit target IP address to place a call. Destination ports can be specified by using *4 (encoding for :) followed by the port number. Examples: a) If the target IP address is 192.168.0.160, enter the 12 digit IP address (e.g. 1921680160) after the voice prompt followed by the # key or wait for 4 seconds. 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, enter the 12 digit IP address + *45062 (e.g. 1921680160*45062) after the voice prompt followed by the # key or wait for 4 seconds.

CALL HOLD

Press the flash button (or hook flash on older models) to place a caller on hold. Press the flash button again to release call hold.

CALL WAITING

If call waiting feature is enabled, call waiting tone (3 short beeps) indicates an incoming call. 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

The HT286 supports both blind and attended transfer: 1. Blind Transfer: Press flash button (or hook flash on older models), dial *87, then dial the number to transfer call and press the # key (or wait 4 seconds) to complete transfer of active call. Expected outcomes: a) A quick confirmation tone (call waiting tone) followed by a dial tone. This indicates the transfer is successful. Hang up or place another call. b) A quick busy tone followed by a restored call (on supported platforms only). The busy tone indicates the transfer failed. c) Continuous busy tone. The phone call has timed out. Note: continuous busy tone does not indicate the transfer has been successful, nor does it indicate the transfer has failed. It often means there was a failure to receive second NOTIFY check firmware for most recent release. NOTE: Enable Call Feature must be set to Yes in web configuration page.

END USER CONFIGURATION 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: User Level: End User Level Administrator Level

TABLE 8: HT286 BASIC CONFIGURATION SETTINGS DEFINITIONS End User Password Web Port IP Address Password to access the Web Configuration Menu. This field is case sensitive with a maximum length of 25 characters. By default, HTTP uses port 80. This field is for customizable web port. There are two modes to operate the HT286: 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 HT286 acquires its IP address from the first DHCP server it discovers from the LAN it is connected. Using the PPPoE feature: set the PPPoE account settings. The HT286 will establish a PPPoE session if any of the PPPoE fields is set. Static IP mode: configure the IP address, Subnet Mask, Default Router IP address, DNS Server 1 (primary), DNS Server 2 (secondary) fields. These fields are set to zero by default. This option specifies the name of the client. This field is optional but may be required by some Internet Service Providers. Default is blank. This option specifies the domain name that client should use when resolving hostnames via the Domain Name System. Default is blank. Used by clients and servers to exchange vendor-specific information. Default is blank. PPPoE username. Necessary if ISP requires you to use a PPPoE (Point to Point Protocol over Ethernet) connection. PPPoE account password. This field is optional. If your ISP uses a service name for the PPPoE connection, enter the service name here. Default is blank. Controls how the date/time displays according to the specified time zone.

Daylight Savings Time

Controls whether displayed time is daylight savings time or not. If set to Yes and the Optional Rule is empty, then the displayed time will be 1 hour ahead of normal time. The Automatic Daylight Saving Time Rule has the following syntax: o start-time;end-time;saving. Both start-time and end-time have the same syntax: month,day,weekday,hour,minute 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 indicating daylight savings rule is based on the day of the month. o hour: hour (0-23), o minute: minute (0-59) If weekday is 0, it means the date to start or end daylight savings is the given date. The day value must not be negative. If weekday is not zero and day is positive, then daylight saving starts on the first day of the week (1st Sunday, 3rd Tuesday etc). If weekday is not zero and day is negative, then daylight savings starts on the last day of the week (last Sunday, 3rd last Tuesday etc). Daylight savings is in minutes. If preceded by a (-), then subtract the number of minutes. The default value for Automatic Daylight Saving Time Rule is US time: 04,01,7,02,00;10,-1,7,02,00;60. Example: US/Canada, where daylight savings is applicable: 04,01,7,02,00;10,-1,7,02,00;60 Daylight savings starts from the first Sunday of April at 2AM and ends the last Sunday of October at 2AM.).

ADVANCED USER CONFIGURATION Log in to the advanced user configuration page the same way as for the basic configuration page. The password is case sensitive and the factory default password for Advanced User is admin. Advanced User configuration includes the end user configuration and the advanced configurations including: a) SIP configuration, b) Codec selection, c) NAT Traversal Setting and d) other miscellaneous configuration. TABLE 10: HT286 ADVANCED CONFIGURATION PAGE DEFINITIONS Admin Password Administrator password. Only administrator can configure the Advanced Settings page. Password field is purposely left blank for security reason after clicking update and saved. The maximum password length is 25 characters. This field contains the URI string or the IP address. e.g. sip.my-voipprovider.com; 192.168.1.200:5066 This field contains the URI string or the IP of the outbound proxy. If there is no outbound proxy, this field SHOULD be left blank. If it is not blank, all outgoing requests will be sent to this outbound proxy. This field contains the user part of the SIP address for this phone. e.g., if the SIP address is: sip:my_user_id@my_provider.com, then the SIP User ID is: my_user_id. Please do NOT include the preceding sip: scheme or the host portion of the SIP address in this field. It is given by VoIP service provider. SIP service subscribers Authenticate ID used for authentication. It can be identical to or different from SIP User ID and given by VoIP service provider. SIP service subscribers account password. It is given by VoIP service provider. SIP service subscribers name which will be used for Caller ID display. Local area code for North American Dial Plan. HandyTone-286 supports up to 7 different vocoder types including G711ulaw (PCMU), G711-alaw (PCMA), G723, G729A, G726-32, and iLBC. Depending on the product model, some of these vocoders may not be provided in standard release. A user can configure vocoders in a preference order that will be offered in SIP INVITE message. This defines the encoding rate for G723 vocoder. By default, 6.3kbps rate is chosen.

G723 Rate:

Page 18 of 28 Last Updated: 1/2009
iLBC frame size iLBC payload type Silence Suppression
This defines the size of the iLBC codec frame. The default setting is 20ms. This defines the iLBC payload type. The default setting is 97. The valid range is between 96 and 127. This controls the silence suppression/VAD feature of G723 and G729. If set to Yes, when a silence is detected, small quantity of VAD packets (instead of audio packets) will be sent during the period of no talking. If set to No, this feature is disabled. This field contains the number of voice frames to be transmitted in a single packet. When setting this value, the user should be aware of the requested packet time (used in SDP message) as a result of configuring this parameter. This parameter is associated with the first vocoder in the above vocoder Preference List or the actual used payload type negotiated between the 2 conversation parties at run time. e.g., if the first vocoder is configured as G723 and the Voice Frames per TX is set to be 2, then the ptime value in the SDP message of an INVITE request will be 60ms because each G723 voice frame contains 30ms of audio. Similarly, if this field is set to be 2 and if the first vocoder chosen is G729 or G711 or G726, 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 phone will use and save the maximum allowed value for the corresponding first vocoder choice. The maximum value for PCM is 10(x10ms) frames; for G726, it is 20 (x10ms) frames; for G723, it is 32 (x30ms) frames; for G729/G728, 64 (x10ms) and 64 (x2.5ms) frames respectively. T.38 (Auto Detect) FoIP by default, or Pass-Through (must use codec PCMU/PCMA) This field defines the layer 3 QoS parameter which can be the value used for IP Precedence or Diff-Serv. Default value is 48 This setting includes two fields. The 802.1Q/VLAN Tag contains the value used for layer 2 VLAN tag. Default setting is blank. And 802.1p priority value contains the value of the priority value. If set to Yes, the device will ignore any SIP message that does not come from the IP address (Source IP in the IP header) that it is registered to. Default is No. This parameter controls whether the IP phone supports the DNS SRV route function. If the HandyTone-286 has an assigned PSTN telephone number, then this field will 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. This parameter controls whether the IP phone needs to send REGISTER messages to the proxy server. The default setting is Yes.

NAT Traversal

This parameter defines whether the phone NAT traversal mechanism will be activated or not. If activated (by choosing Yes) and a STUN server is also specified, then the phone will behave according to the STUN client specification. Under this mode, the embedded STUN client inside the phone will attempt to detect if and what type of firewall/NAT it is behind by sending appropriate request to the specified STUN server. If this field is set to Yes with no specified STUN server, then the phone will only periodically (every 20 seconds by default) send a blank UDP packet (with no payload data) to the SIP server to keep the mapped port open on the NAT. The HandyTone-286 sends a UDP package to the SIP server periodically in order to keep the port open on the router. This parameter defines the interval time that HT286 send the UDP package. The default setting is 20 second. NAT IP address is used in SIP/SDP message. Default is blank.
Use STUN keep-alive to detect WAN side network problems. If keep-alive request does not yield any response for configured number of times, the device will restart the TCP/IP stack. If the STUN server does not respond when the device boots up, the feature is disabled.

SIP Extension to notify SIP server that the unit is behind the NAT/Firewall. Default is No. When set to Yes a SUBSCRIBE for Message Waiting Indication will be sent periodically This parameter allows the user to configure a User ID or extension number to be automatically dialed upon off hook. Please note that only the user part of a SIP address needs to be entered here. The phone will automatically append the @ and the host portion of the corresponding SIP address. Default is Yes. If set to Yes, call features using star codes are supported locally. Conference mode, default option is No. If set to yes, the feature code for coference *23 would be disabled. Default is No. Default is No. This parameter specifies the mechanism to transmit DTMF digit. There are 3 modes supported: 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. This parameter sets the payload type for DTMF using RFC2833 Default is No. If set to yes, flash will be sent as DTMF event. The amount of time the hookflash is pressed that will cause the device to on hook. Default is 800ms. Selects the impedance of the analog telephone connected to the Phone port.

Volume Amplification Handset volume adjustment. RX is for receiving volume, TX is for transmission volume. Default values are 0dB for both parameters. +6dB generates the highest volume and -6dB generates the lowest volume. Powerline Ring Tone Call Progress Tones This setting allows user to configure the ringing frequencies and cadences. Using these settings, users can configure various call progress tone frequencies and cadences according to their country standard. By default they are set to North American standard. Frequencies should be configured with known values to avoid uncomfortable high pitch sounds. ON is the period of ringing (On time in ms) while OFF is the period of silence. In order to set a continuous ring, OFF should be zero. Otherwise it will ring ON ms and a pause of OFF ms and then repeat the pattern. Up to three cadences are supported. Default is No. If set to Yes, echo canceller is not used.

SAVING THE CONFIGURATION CHANGES
After making a change, click the Update button in the Configuration page. The HT286 will display a screen to confirming changes. Reboot or power cycle the HT286 to enable the changes.
REBOOTING THE HT286 FROM REMOTE
The administrator of the HT286 can remotely reboot the HT286 by clicking the Reboot button at the bottom of the configuration page. When finished, re-login to the HT286 after waiting about 30 seconds.
CONFIGURATION THROUGH A CENTRAL SERVER
Grandstream HandyTone ATA can be automatically configured from a central provisioning system. When HandyTone ATA boot up, it will send TFTP or HTTP request to download configuration file cfg000b82xxxxxx, where 000b82xxxxxx is the MAC address of the HandyTone ATA. The configuration file can be loaded into devices via TFTP or HTTP from the central provisioning server, so the service provider or an enterprise with large deployment of HandyTone ATAs can easily manage the configuration and service provision to individual devices remotely. 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 customers 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/configurationtool.html

MANAGING 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 devices periodically check with either Firmware Server or Config Server, whenever they are defined. This allows the device periodically check if there are any new changes need to be taken on a scheduled time. By defining different intervals in P193 for different devices, Server Provider can spread the Firmware or Configuration File download in minutes to reduce the Firmware or Provisioning Server load at any given time.
