1 1. Introduction Product Overview The stand-alone VoIP Gateway carries both voice and facsimile over the IP network. It supports SIP industry standard call control protocol to be compatible with free registration services or VoIP service providers’ systems. It works in two different modes: UA (User Agent) or Server. As a standard user agent, it is compatible to all well-known Soft Switches and SIP proxy servers.
2 Product Features ● SIP (RFC 3261) compliant ● Optional server enables small businesses to build up private VoIP network (SIP model) ● QoS support guarantees voice bandwidth in a busy network ● Supports IP TOS (Type Of Service) ● T.30 (G III) / Real Time T.38 / Secured T.
3 Hardware Description Front Panel Power Indicator: Green light indicates a normal power supply. Run Indicator: Blinking green light indicates normal operation. Alarm Indicator: When the system starts up, the red light will blink. It also indicates the gateway’s abnormal operation. P1 – P16 stands for Port 1 – Port 16: Connect to your analog telephone. WAN stands for the WAN Port Indicator. LAN stands for the LAN Port Indicator.
2. Installation and Applications Network Interface The network interface is divided into 3 basic modes as described below: Gateway can be assigned with a Public IP Address Gateway can be built under the existing NAT Gateway Assigned with a Public IP Address The gateway will have a Public IP address for Internet connection regardless of whether it is a static IP address, DHCP (using a Cable Modem), or PPPoE (Dialup / ADSL).
5 Gateway in a NAT network The gateway uses a virtual IP address and the IP sharing function of other systems to connect to the Internet. LAN IP address of IP sharing Please avoid IP address 192.168.0.1-192.168.8.254 (You may need to change the settings of IP sharing or change SIP series Gateway LAN Port IP address) Gateway IP Settings Set as static IP address, and assign the LAN IP address of the IP sharing to the Default Gateway.
Telephone Interface Description Example for DVG2016S: DVG2016S connecting directly to phone sets After connecting telephone sets to P1-P16, users can make direct calls, (P1-P16 are FXS interfaces). Each set acts as an independent extension line. Integrating the DVG2016S with PBX P1-P16 is FXS interfaces, and some of them can be connected to telephone sets for direct calls. Others can be connected to the PBX so other extension lines can make VoIP calls.
7 3. Setting the Gateway through IVR VoIP transmits voice data (packet) via the Internet to achieve telecommunications. This means that the telecommunication quality is closely related to the whole network environment. If any one of the telecommunicating parties has insufficient bandwidth or frequent packet loss, the telecommunication quality will be poor. Therefore, an excellent telecommunication can only be created when Gateway is connected to the Internet and when network environment is stable.
Instructions FXS Port: Connected to telephones. To enter IVR mode, enter “ * * password #” after hearing the dial tone. When you hear a second dial tone, the system is in IVR mode, enter the function code. (Please refer to the Advanced Settings on page 35 for these codes) Example: The factory default code is blank. Enter “**#”. You are now in IVR setting mode, enter the desired code. E.g.: if the code is 1234, then enter “**1234#”.

1. Setting a Gateway with WEB Browser The gateway allows users to make settings using a web browser. After opening a browser, enter Gateway’s IP address as the website address in order to enter the Web configuration screen as shown in the following diagram. You can also enter ”101” from the handset to inquire about the current WAN Port IP address. The factory default LAN Port IP address is 192.168.8.254. Instructions Open an Internet browser.
15 Listen Port UDP: It is not necessary to change the protocol of the communication port used by the gateway. RTP Starting Port UDP: The initial value of port number for transmitting voice data among Gateway(s). Each line requires 2 ports (RTP/RTCP). It is not necessary to change these.
and Line 2 is using 9002 and 9003, and so forth. IP Configuration (Setting WAN Port) There are four methods of obtaining a WAN port IP address: 1. Static IP 2. DHCP, means a Dynamic IP (Cable Modem) 3. PPPoE (Dialup ADSL) 4. PPTP. Using the DHCP and PPPoE for obtaining an IP address may vary. If not familiar with the network connection, please contact your local ISP. Setting Dynamic IP (DHCP) Click “DHCP” to obtain a Dynamic IP address, then click the “Accept” button at the bottom of the screen.
17 Select “PPTP” and enter the IP Address, Subnet mask, PPTP Server, PPTP ID and Password. Then click the “Accept” button at the bottom. BigPond (for Australia use only) Click “BigPond Cable” Enter User Name and Password. Login Server is optional. Then click the “Accept” button at the bottom. (DNS) Settings Domain Name Server (DNS): While a gateway is accessing another gateway or computer with a hostname, it will look up the IP address from the DNS provided by ISP.
Some Internet Service Providers (ISP) assigns the bandwidth via the MAC (Media Access Control) Address. You can click the " Clone" button to copy the MAC address of the Ethernet Card installed in the computer used to configure the device. It is only necessary to fill in the field if required by your ISP. The “Your MAC Address” will be blank as you log in through WAN port.
19 Network Settings (LAN) LAN interface mode※ Router: The system serves as a router with NAT. Bridge: The system serves as a bridge between WAN port and LAN port without NAT. (LAN default gateway will still be accessible for configuration). LAN IP/Subnet mask Gateway LAN Port IP address and the subnet mask value. Port of Web Access from WAN: Http port for WAN. To make this setting, the LAN Port must be used. WAN Port cannot make this setting. Always use port 80 when connecting to LAN port.
QoS Settings WAN QoS QoS (Quality of Service): Sets an external bandwidth to ensure sound quality during transmission (When this function is enabled, the voice packet has the highest priority to ensure telecommunication quality while less bandwidth is assigned for data transmission). Some models of the gateway without this function can adjust the bandwidth automatically.
21 NAT/DDNS NAT Traversal If a Gateway is set up under an IP sharing setting, you can select either the NAT or STUN protocol. NAT Public IP: The IP address used by the gateway should be a virtual address. Further more, users must set the Virtual Server Mapping in the NAT Server (A virtual server is defined as a Service Port, and all requests to this port will be redirected to this specified the server IP address).
DDNS These settings are only necessary when the gateway is set up under a NAT that uses a dynamic IP address and do not support DDNS.
23 Choose a DDNS Server: The current system allows users to choose either DynDNS、TZO、3322.org、 PeanutHull or a private server. Please apply for a user account before choosing a service provider. Server address: Sets up the IP address or URL (Uniform Resource Locator) of the DDNS Server. Hostname: The URL of the system (or NAT) – apply from a domain name registration providers. Login ID and Password: The ID and password are used to log into the DDNS server.
Enable: Enable a line; if some lines are not used, disable them (Pause Function) to avoid unnecessary waiting when an incoming call is diverting to this line. Hotline Functions FXS port: When the user picks up the phone, the gateway automatically dials your assigned hotline number. When in hotline mode, other lines cannot be used. Hot Line No.: Enter the hot line number for an automatic dialing function. Warm Line: When the warm line function is in use, user can dial a number.
25 Hunting/Ring: It is able to set FXS group hunting using simultaneous ring or sequential ring. Sequential Ring Time: To set the ring time of each port, when sequential ring is chosen. SIP All Call through OutBound Proxy：An outbound proxy server handles SIP call signaling as a standard SIP proxy server would. Furthermore, it receives and transmits phone conversation traffic (media) in between two talking gateways.
SIP Message Resend Timer Base: SIP packet will resend if response didn't arrive in the base time set in this column. It will send again at "base time" * 2, and send again at "base time" *2 *2. The max of resend time is 4 sec. Resend will stop/restart when total resend 20sec has reached. Max. Response Time for Invite: If the destination does not reply in the set time, this call is failed. Invite URL need ‘user=phone’: There is ‘user=phone’ in invite packet.
27 Enable Support of SIP Proxy Server / Soft Switch: Enable the functions to inter-work with Proxy Server / Soft Switch. When SIP Proxy 1 and 2 are enabled, the system will register to SIP Proxy 2 after all lines are failed to register to SIP Proxy 1. SIP Proxy 2 is a backup system. Proxy Server IP/Domain: Enter the Proxy Server IP address or URL (Uniform Resource Locator). You can set 3 redundant Proxy spread by semicolon. EX: 61.123.231.1;12.34.56.78;proxy.sip.
Initial Unregister: After rebooting, it is unregistered first and then do the general registry process. Enable Message Waiting Indication: The system will play a tone to remind users that there are messages in SIP Server. Proxy-Require: Some SIP Sever need SIP UA to add this header to it's sip message. FXS Representative number registers to Proxy: Assuming that your registered ID and password are individual, the settings should be as above.
29 Calling Features Do Not Disturb: It will only be able to call out when it is enabled. Unconditional Forward: All incoming calls will be forwarded to the “Forwarding Number” automatically. If it forwards to FXO, it only make FXO hook off, not make FXO dial out. Busy Forward: Forward the incoming call to “Forwarding Number” when the port is busy. No Answer Forward: Forward the incoming call to “Forwarding Number” after ring timeout expires without answer.
Calling Feature Instructions: Call Hold: Ongoing call will be put on hold after FLASH button pressed on the phone set. The gateway will play a repeating music to the remote end. Call Transfer: Ongoing call will be put on hold after FLASH button pressed on local phone set (gateway plays a repeating music to the remote end). Meanwhile, local user can dial out to another number after dial tone observed.
31 Advanced Options There are two levels to enter Web. Administrator is able to change all settings. Web UI only changes some settings. NOTE: Enter new Login ID and password for two levels. Web UI auto log out: When logging in a web page, if a user does not act within the effective time range, the user will be disconnected from the web page to allow others to login. Dial Wait Timeout: Use it to set the waiting time for the user’s first key pressing when dialing a number.
Enable Out-of-Band DTMF: To send DTMF keys (0~9, *, #,) follow the RFC2833 rules or via SIP Info. Enable Hook Flash Event: The gateway will deliver the flash signal to remote party via RFC2833 or SIP Info. Payload Type：Payload type of RFC2833. Uses Second CPT for VoIP Call: This function is usually applied when the user selects VoIP as the primary path for outgoing calls and PSTN as the backup.
33 the sound quality and occupied bandwidths are also different. It is recommended to use the default provided (G.723.1) because it occupies less bandwidth and will provide better sound quality. Jitter Buffer: Adjusts the jitter to receive a packet. If the jitter range is too wide, it will delay voice transmission. Silence Suppression: If one side of a connection is not speaking, the system will stop sending voice data (package) to decrease bandwidth usage.
Drop Silent Call Timeout: Set the time to hang up the phone.
35 Digit Map There are 50 sets of leading digit entries to choose voice routing interface – Auto select, PSTN or VoIP. Default Call Route: The default call route can be Auto, VoIP and Deny. Auto (VoIP first): The call route is VoIP first, and the next is Deny. VoIP: The call route is VoIP only. Deny: The call will be deny if the dial-out number is not in the table. Enable: Enable detection of this entry. Leading Digits: The leading digits for the gateway to scan while user is dialing.
Method 1- Single mapping: Fill a short code into the “Speed Dial Code” column, and enter the desired phone number into the “Number To Dial” column. For example, pick up the handset and dial 55＃ and the system will dial 32568791. Method 2- Multi mapping; Fill the prefix code into the ” Speed Dial Code” column and the format to transfer into the “Number To Dial” column. For example, pick up the handset and dial 301＃, and the system will dial 521301.
37 CDR Settings The user can set up a CDR Server to record call details for every phone call. The present CDR provides the call detail recording in a text file and if needed. it can be imported to prepare for an analysis report. Send record to CDR Server: Enables the call detail recording function. CDR Server IP: Enter the IP address of the CDR server. Port: Enter the listen port of the CDR server.
System Information This page shows that the status of VoIP Gateway. There are Port Status, Server Registration Status, WAN Port Information, LAN Port Information and Hardware.
