Legal and Regulatory Information ...14 Note: this reference is intended to provide a quick overview of NetComm’s SmartVoice VoIP Gateways, using the V431 (3 FXS + 1 FXO) as an example in typical applications. The target reader is someone who has already gained knowledge and basic skills in VoIP and PBX systems.

    SeCTION 1: BeFORe CONFIGURING The V431 1.1 Default Network Settings: LAN Port: 192.168.8.254/24; LAN DHCP Server: enabled; WAN Port: 192.168.1.2/24; 1.2 Save Settings: Some changes in settings won’t take effect until the V431 system is restarted. Please click “Accept” on web configuration page to commit your changes and then click “Save” Settings” into V431 flash. To restart the system select “Restart” and click “Accept”. These “Save Settings” and “Restart” options are under System Setting > System Operation sub-menu. Fig 1-1 shows the save setting and restart screen.

  • Page 5: Internet Access Bandwidth Recommendation

    1.3 Internet Access Bandwidth Recommendation: To guarantee the V431 has enough bandwidth for carrying VoIP traffic, we suggest providing a dedicated 256 Kbps (upstream) ADSL link to the V431. The reason for this is that real bandwidth used by VoIP traffic is much more than the codec bit rate itself because the RTP, IP and ATM header adds additional overhead on raw VoIP payloads. 1.4 Querying network settings using the V431 IVR system The V431 provides a convenient IVR function which allows users to query and set some of V431 basic configurations using an analog telephone handset. It is very useful when the users check and set the IP address of the V431. Following are simple instructions of using the IVR. For complete reference, please see its the user guide. To access IVR setting mode: lift a telephone handset connected to a FXS port and input “**password#”; the default “password” is “admin”, so when the V431 is in default settings the users input “***4144534954#” to enter the IVR. Note: three asterisk “*” is required for type in default password “admin” as the third one indicates the input is alphabets rather than numbers.

    CONNeCTING V431 TO INTeRNeT 2.1 Internet Access Fig 2-1 shows a simplified network connection of the V431. Methods of traversing NAT/Firewall are also discussed below. Eth. Switch Port 4 V431 Figure -1: V431 broadband access & Ethernet connection Figure 2-1: V431 broadband access & Ethernet connection WAN port (public IP) When the V431 has a public IP for Internet connection regardless of whether it is a static public IP, dynamic public IP via DHCP or PPPoE, the V431 will be exposed to the Internet and should have no problem to traverse a NAT/Firewall. WAN port (private IP): when the V431 WAN port is assigned with a private IP, NAT/firewall traversal settings need to be configured to ensure the V431 can support bi-directional conversations.

  • Page 8 In the V431 NAT traversal section, the user needs to specify the fixed public IP of the broadband router and check ‘NAT public IP’ option. 2. STUN: using the STUN protocol can help a VoIP device to detect the presence and type of NAT which ensures bi- directional conversation and avoids configuring broadband Internet router. However, the STUN cannot traverse all types of NAT. The following image shows you an example of STUN configuration. 3. UPnP: this function only works when the broadband router supports UPnP and has it enabled. Note: many routers claim support for UPnP but do not work very well. So, be cautious to use this method in order to allow the V431 to traverse NAT. V431 VoIP Gateway Quick Start Guide Fig -4 Fig -5: STUN setting YML859 Rev1 www.netcomm.com.au...

    The following images illustrate typical V431 SIP client settings. The analog ports of the V431 can be registered under one SIP account (representative account) or individual SIP accounts for each FXS line. Fig 3-1: SIP configuration using different accounts for each FXS port Fig 3-: SIP configuration using a single account for all FXS ports YML859 Rev1 www.netcomm.com.au V431 VoIP Gateway Quick Start Guide V431 VoIP Gateway Quick Start Guide...

    Note: if you use representative account to register all FXS ports, you need make sure the SIP server that the V431 registers on supports multiple concurrent active calls using the SIP representative account. Check this with your VoIP service provider.

    SeCTION 4: VOIP APPLICATIONS 4.1 Basic Usage: Stand Alone VoIP gateway The Fig 4-1 shows a diagram in which the V431 is used as a stand alone VoIP gateway. Port 3 V431 Figure 4-1: V431 works as an stand alone VoIP box General FXS operation behavior: The operation of the FXS ports of the V431 is straight forward: lift up a handset and dial the destination number to make VoIP calls. General FXO operation behavior: The FXO port of the V431 allows the user to route calls between the PSTN and VoIP networks. Following are scenarios of different types of call routing. When an incoming VoIP call reaches the VoIP phone number of the FXO port, the FXO port will pick up the landline that it is connected to. A dial tone generated by the landline will be provided to the calling party through the VoIP voice channels. At this point, the user is able to dial the destination number (a landline or mobile number), and the V431 will use the landline to establish the call.
  • Page 12 Call Model 2: Calling party (from PSTN network) calls PSTN number of the FXO port connected to landline (called party) The FXO loops the landline (off hook action) and a voice prompt from the V431 prompts calling party to enter number The calling party inputs a VoIP phone number or extension phone number The FXO port will use its VoIP phone number to establish the call through the VoIP network. enable hotline and hotline Dial Wait on the FXO port When the “Hotline” and “Hotline Dial Wait” functions are used in the FXO port, the V431 will divert an incoming call (from PSTN network) to an extension line after a set wait time. For example, assuming the assigned hotline for the FXO port is extension 601 and the wait time is 6 seconds. If no VoIP number or extension number is dialed within 6 seconds, the call will be automatically diverted to this assigned hotline (ext. 601). This feature might be very useful when the V431 is used with a PBX because the diverted call will ring on the FXS port which could be the receptionist. The PBX will answer this call and transfer the call to a person that the calling party would like to speak to. Fig 4-2 shows an example of hotline configuration.

  • Page 13: Advanced Usage: Connecting With Pbx System

    PBX can keep the old convention for people dialing out (e.g. dialing “0” to get an available CO line (exchange line)) from normal landline hunting group to allow people to call outside using PSTN network. However, the PBX can be programmed to put CO4 ~ CO6 into another CO line hunting group which consists of FXS1 ~ FXS3 VoIP links, and use another prefix to get VoIP lines by dialing “9”. Therefore, practical usage could be like this: For local calls: dial “0” > CO hunting group 1 > any available landline For STD & international calls: dial “9” > CO hunting group 2 > any available VoIP line (FXS line) The V431 might be registered with a SIP server using one SIP account. This has two advantages: The calling party only needs to remember a single VoIP number to call the V431. When an incoming VoIP call reaches the V431, it will choose any available FXS line to establish the call. In contrast, if each FXS line uses a different account to register and a specific line is engaged, at the point the other party calls the line, then the calling party has to call this line another time or call other FXS lines of the V431. The FXO can be used to hop on the PSTN network if a call is initiated from the VoIP network, or hop on the VoIP network if call is initiated from the PSTN network (for FXO port processing behavior, please see Section 4: General FXO operation behaviors).
