It also indicates abnormal gateway behaviour.
Rear Panel (all models) Phone ports are telephone ports (FXS) to be connected to telephone sets or PBX CO ports. Line ports (FXO) are to be connected to PSTN lines (telephone lines from a PSTN network). NOTE: Do not connect FXS ports to each other. Also, do not connect any FXS port directly to a PSTN line or internal PBX.
Installation and Applications Connecting your SmartVoice Gateway(s) 1. Connect the WAN port of your SmartVoice Gateway to your Broadband Modem using an ethernet cable. . Connect the power adapter to your SmartVoice Gateway and plug it into a powerpoint. Please use the power adapter that comes with VoIP gateway. Using an adapter other than the one supplied with the VoIP gateway, may cause problems and will affect the warranty of the product.
Network Connections Possible network connections are divided into 3 basic modes as described below: • Gateway can be assigned with a Public IP Address • Gateway can be installed under the existing NAT • Gateway can be assigned with a Public IP address and serve as an IP sharing router. Gateway Assigned with a Public IP Address The VoIP gateway will have a Public IP address for its Internet connection regardless of whether it is a static IP address, DHCP (using a Cable Modem), or PPPoE (Dialup / ADSL).
Gateway behind a NAT/Firewall Network The VoIP gateway uses a private IP address and the Internet sharing function of other systems to connect to the Internet. The following diagram shows a typical network connection in which broadband devices such as an ADSL router work in router (NAT) mode so that the gateway is behind a NAT/Firewall.
The table shown below lists possible solutions for different network scenarios. LAN IP address of Internet sharing WAN IP of SmartVoice gateway NAT Traversal There are three ways to configure a SmartVoice gateway to traversing NAT in Internet sharing devices. For details, please refer to page 6.
Gateway Assigned with a Public IP Address and Serving as an Internet Sharing Device The SmartVoice gateway will have a Public IP address, regardless of whether it is the public IP from a static setting, DHCP (using a Cable Modem), or PPPoE (to connect to your ADSL account), and can use the built-in Internet sharing functions to allow other PCs attached to SmartVoice gateway LAN ports to share the Internet connection.
Telephone Connection Example of SmartVoice Gateway using FXS interfaces SmartVoice Gateway connecting directly to phone sets After connecting telephone sets to Phone1-Phone4, users can make direct calls (Phone1-Phone4 are FXS interfaces). Each set acts as an independent extension line. Integrating the SmartVoice Gateway with PBX Phone1-Phone4 are FXS interfaces, and some of them can be connected to telephone sets for direct calls.
Example of SmartVoice Gateway using FXO interfaces SmartVoice Gateway connecting directly to the Telephone Line of a PSTN Line1-Line4 are FXO interfaces and can all be connected to a PSTN to serve as a bridge between the PSTN and VoIP network. Integrating the SmartVoice Gateway with PBX Line1-Line4 are FXO interfaces and can be connected with PBX extension lines (this is exclusively for an analog interface, and is not applicable for a digital interface).
Example of SmartVoice Gateway using a combination of FXS and FXO ports Phone1-Phone are FXS interfaces and can be directly connected to telephone sets for direct calls. Line1-Line are FXO interfaces and can be connected to PSTN lines to serve as a bridge between the PSTN and other VoIP telephones.
Configuring the Gateway via WEB Browser The gateway also allows users to change gateway settings using a web browser. After opening a browser window, enter the gateway’s IP address as the website address in order to enter the Web configuration screen as shown in the following diagram.
Network Settings The network settings are used to set the gateway’s communication ports, IP configurations, DNS and DHCP server etc. • Current WAN IP Address: The IP address of the WAN port. • Listen Port UDP: It is not necessary to change the protocol of the communication port used by the gateway, unless it conflicts with ports used by another device in your network.
Setting Dynamic IP (DHCP) Click “DHCP” to obtain a Dynamic IP address, and then click the “Accept” button at the bottom of the screen. To save the settings click System Operation to select “Save Settings”, “Restart”, and then click the ”Accept”...
BigPond Click “BigPond Cable”. Enter User Name and Password and 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 the ISP. The ISP whilst negotiating with PPPoE or DHCP usually assigns the DNS information.
LAN interface mode • Router: The system serves as a router. • Bridge: The system serves as a bridge between WAN port and LAN port. (LAN default gateway will still be accessible for configuration). Network Settings (LAN) • Network Settings (LAN): The gateway’s LAN IP address and subnet mask value. Please note that the gateway is built under NAT: The gateway’s LAN IP address cannot be in the same section as the Internet sharing devices, or else it is unable to make or receive calls.
QoS Settings WAN QoS • QoS (Quality of Service): Sets true bandwidth of your Internet connection 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 VoIP gateway without this function can adjust the bandwidth automatically.
NAT/DDNS (NAT Traversal) If a gateway is set up behind an Internet sharing device, you can select either the NAT or STUN protocol. • NAT Public IP: The IP address used by the gateway should be a private address. Furthermore, users must set the Virtual Server Mapping in the Internet sharing device (For example, a virtual server is usually defined as a Service Port, and all requests to this port will be redirected to this specified server’s private IP address).
DDNS These settings are only necessary when the gateway is set up behind an Internet sharing device that uses a dynamic IP address and does not support DDNS. You need to apply for an account with a DDNS service from www.dyndns.org before you type in the following information.
Telephony Settings Prefix Number Rules • Trunk Dial Out Verify/ Trunk Dial Out Replace: The system will transfer the number for all transit out calls through the FXO port. For example: If you transit out with 01907123456, the system will replace it with 190601 907123456. If you transit out with 008621123456 the system will replace it with 190200 8621123456.
• FXO Hunting Default Dial-Out: This will take effect as FXO Hunting VoIP call in option is set to Default Dial-Out. FXO Line VoIP call in options: • The usage of this option is as same as FXO Hunting VoIP call in option. The Default Dial-Out refers to individual lines rather than a hunting group.
• Group Hunting: Select group hunting when there is an incoming call and the gateway will automatically assign an unassigned call according to the Hunting Priority. If Line does not want to be set as an assigned line to receive any inbound calls, the function can be disabled. Users can also use the Up or Down key to adjust hunting priority (No setting is required for the FXO interface).
SIP Settings • 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 communication parties. This option tells the gateway to send and receive all SIP packets to the destined outbound proxy server rather than the remote gateway.
E.164 • International Call Prefix Digit: Enter the International call prefix. • Country Code: Select the desired country code. • Long Distance Call Prefix Digit: The long-distance prefix digit for making a long-distance call. • Area Code: Please enter the area code. • E.164 Numbering: To invite Proxy to follow the E.164 rule. It depends on the Proxy. NOTE: All settings in this section are specific to your VoIP network.
• Proxy Server Realm: This is used for gateway SIP account authentication in a SIP server. In most cases, the gateway can automatically detect your SIP server realm. So you can leave this option as blank. However, if your SIP server requires you to use a specific realm you can manually type it in here.
• Invite with ID / Account: VoIP gateway can be invited to a VoIP trunk gateway w/o registering with a Proxy. Please contact your VoIP provider. As there are various Proxy Server providers, NetComm has designed the gateway to be compatible with as many SIP VoIP networks as possible, and according to RFC standards. If any registration problem occurs, please consult your VoIP provider.
Private Network Users can establish a private network by using the Phone Book Manager Service. The Phone Book Manager Service is different from using the Proxy. The gateway is able to register with the Phone Book Manager Service and the SIP Proxy at the same time. Server Settings • Enable Phone Book Manager Server: It allows other Gateway users to register the IP address and Gateway Number in this Phone book manager server.
NOTE: When the gateway is configured as Phone Book Manager server, it can also be configured as a client at the same time by enabling Register to Phone Book Manager option. This means the gateway also shares its Private Gateway Number to other clients which register on it.
Calling Features • Do Not Disturb: It will only be able to call out when it is enabled. All incoming calls will be restricted. • 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”...
Advanced Options NOTE: There are two levels to enter Web. Administrator is able to change all settings. Web UI only changes some settings. • Administrator’s name and Password: Enter administrator name and password, which has the highest level of control of the gateway. • Web UI Login ID and Web UI/IVR Password: Enter login ID and password when you log into the Web interface/IVR of the gateway as a normal user.
• Payload Type: payload type of RFC833. • 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. By enabling this function, the gateway will generate a different set of tones to inform the user that VoIP is in service.
Line Settings • Listening Volume: Adjusts the hearing volume. • Speaking Volume: Adjusts the speaking volume. • Tone Volume: This setting will be applied to all tones generated by the VoIP gateway including Dial Tone, Busy Tone, and so on. • Flash Time: FXS: Used to adjust the detection period of flash signal from the phone set connected to the FXS port.
Codec Settings • Preferred Codec Type: Since different voice codecs have different compression ratios, so the sound quality and occupied bandwidths will also be different. It is recommended that you use the default provided (G.79) because it is popular and will provide better sound quality. • Jitter Buffer: Adjusts the jitter to receive a packet.
Fax Settings • T.38: The T.38 protocol is used for better and faster facsimile transmission. So it is recommended to enable this function to gain better fax quality. When this function is enabled, please select UDP or TCP. If selecting TCP and some gateways cannot use the Fax function, please select UDP instead. NOTE: When a FAX tone is detected in a call, the gateway will automatically switch from voice mode to fax mode.
Drop Inactive Call • Silence Detection Threshold: The volume below the threshold is used as a standard to determine whether or not to hang up the phone. • Drop Silent Call Timeout: If the detected volume is below the threshold and the time exceeds the silence detection interval, the system will hang up the phone automatically to avoid keeping the line engaged.
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, PSTN and Deny. Auto (VoIP first): The call route is VoIP first, and the next is PSTN. VoIP: The call route is VoIP only.
Phone Book The system can set up and store 100 phone numbers in the phone book and provide an IP address query when calling other Gateway(s). If no Phone book manager is set within a Gateway group, then all Gateway systems have to set up phone data for each VoIP gateway to communicate with each other. • Gateway Name: Enter the Gateway’s code or an easy-to-remember name.
Speed Dial This system can set up 100 numbers for speed dialing. Setting methods are as follows: 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 3568791.
Caller Filter This function is used to allow or deny the SIP Invite message from the Proxy list ONLY. • Filter IP Address: Enter the IP address that you would like to allow/deny. • Subnet mask: Enter the subnet mask that is applied to the IP that entered in the Filter IP address field.
Transit Call Control If you wish to restrict a general user (one who is not required to enter the PIN code) to local calls only and prohibit him/her from making long-distance calls started with a prefix “0”, do the following steps: 1.
Dialing principle to enable PIN code *Inbound Call Control PIN Code * Outbound Call Control PIN Code * Phone number Using * to the separate PIN code and the phone number based on actual settings. The PIN can also be omitted.
Long-Distance Control Table This table controls the level of authority of an outgoing (transit out) call that is dialed through FXO and diverted to PSTN, as below: Descriptions: • Digit strings in this table are prefixes that the gateway will check on dialed numbers in transit out calls.
CPT/Cadence Settings CPT/Cadence setting parameters serve as the basis of an FXO interface to determine whether or not a PSTN-call receiving party has hung up the phone. If the following parameters differ from the parameters of the actual assigned lines, it could cause the FXO to continue to engage a line. Busy Tone Cadence Measurement • Busy Tone Cadence Measurement and auto learning: Provides a solution of FXO integrated with PSTN or PBX.
NOTE: To cope with different local PSTN and different PBX models, the system provides auto busy tone cadence learning to prevent the FXO from engaging a line. However, if the line of the receiving party is engaged and his/her PSTN uses a voice prompt to replace the traditional beep sound, then the system would not be able to detect a busy tone.
Direct Connection to PSTN Note: The above diagrams show a 4-port SmartVoice gateway for illustration purposes. An 8 port SmartVoice gateway could also be used depending upon your network requirements. • Connect one of the trunk lines to the Gateway FXO Port. • The line of “Dial Number”...
Once detection of a busy tone is in progress, the system will dial the number to be tested (in this case 36008913). After it rings pick up the phone and enter”#”, then hang up. The system will then detect a busy tone automatically.
Connected to a PBX Extension Line If the gateway is connected to a PBX extension line, then the busy tone of both the PBX and the PSTN must be detected. Connecting to a PBX extension line and detecting the busy tone of the PBX 36008913 Note: The above diagrams show a 4-port SmartVoice gateway for illustration purposes.
Connected to a PBX extension line to detect the busy tone of PSTN 36008913 Note: The above diagrams show a 4-port SmartVoice gateway for illustration purposes. An 8 port SmartVoice gateway could also be used depending upon your network requirements. • Connect one of the PBX extension lines to the gateway’s FXO Port.
Filling in the CPT Table Fill in the table after the detection is completed as below, where the values are the frequency and On- and-Off ratio detected. Please click the “Accept” button. If connecting the Gateway to a PBX extension line, please do not set the detected busy tone of the PBX and the PSTN in the same set, otherwise the value detected the first time will be overwritten.
Current Status and System Information These two pages show that the status of VoIP Gateway. There are Port Status, Server Registration Status, WAN Port Information, LAN Port Information and Hardware. • Port Status: It includes if each port registers to Proxy successfully, the lasted dialed number, how many calls each port had since the system is start, etc.
RTP Packet Summary Displays the information of the last finished call. It contains peer IP, peer port, packets sent, packet received and packet lost. Press the Refresh button to get the latest RTP Packet Summary. Voice quality can be degraded significantly if packet lost exceeds 5%. To avoid high packet loss, you need either to increase your broadband bandwidth or configure your QoS in your broadband router.
STUN Inquiry Using “STUN Inquiry” to detect your IP sharing device’s NAT type and communication between STUN server and client (built-in SmartVoice gateway). NOTE: If detected NAT type is “Symmetric NAT”, then the gateway is not able to traverse the NAT of your Internet sharing devices. This is not a flaw of the gateway’s design, but nature of STUN protocol design.
Port Filtering Port filtering enables you to control all data that can be transmitted in routers; principles of filtering- --When the port used at the source end is within the limited scope, it will be filtered without transmission. • Enable port filtering: whether to enable this function or not. • Port Range: Set the range of port to be filtered, suppose it is 80 and when use protocol is Both or TCP, all computers will be unable to use the services of http (port 80)—...
