  • Page 16: Switching On The Gateway

    2.2.2 Switching on the gateway Caution Connect the gateway to the nearest wall socket using the supplied external power supply (IP 400, 100-240 V). Only use the external power supply. Other power supplies could damage the gateway. The mains socket must be close to the device and easily accessible. The only way of interrupting the power supply to the device is by removing the mains lead of the device, or of the external power supply, from the mains socket.

This makes the gateway operate like an Ethernet Hub for your computer.
  • Page 22 With Windows, this is done by adjusting the settings for the TCP/IP- protocol accordingly in the Network area in System control. In this case, the com- puter must be restarted. The installation can be concluded, using your Web Browser. In this manual, we describe the procedure using the Web Browser, which is usually the most convenient one, for common application scenarios.
  • Page 23 If you want to configure further gateways in the same way, you have to delete the assignment of the IP address to the hardware address first before connecting the next device to your PC. This is necessary, as the new device has to respond to the same IP address, despite having a different hardware address.

  • Page 24: General Information On Configuration

    Here, you specify the parameters for your Internet or intranet access, if you also intend to use the gateway as an ISDN or a VPN router. The innovaphone VoIP gateway IP 400 can also be used as ISDN router and as VPN router (PPPoE).

Reset is used for an immediate restart, whereas Reset when idle only restarts if there are no active calls. This prevents existing calls from being disconnected by a restart.

  • Page 28: Configuration Of The Ip Interfaces

    Configuration of the IP interfaces Configuration of the Ethernet interface The Ethernet IP interface is usually configured when the gateway is commissioned and does normally not need to be changed again. If this does need changing, you can adjust the settings in the IP Interfaces > Ethernet Interface configura- tion applet.
  • Page 29 • The Full duplex checkbox is usually not activated. This option is only necessary with the IP 400. The IP 3000, IP 3000DD, IP 800, IP 202 and the IP 21 negotiate the full duplex mode auto- matically with the switch or hub.

  • Page 30: Dhcp Configuration Options

    4.1.1 DHCP configuration options Besides the IP address actually assigned, your gateway's DHCP client processes the DHCP options specified in Table 5, provided that they were supplied when the DHCP lease was granted. Options supplied via DHCP always overwrite any parameters defined in the gate- way configuration.

  • Page 31: Full Duplex Ethernet

    Set your Ethernet switch to always run in full duplex mode, for the port to which the IP 400 is connected. This is necessary, as the operating mode of the IP 400 is not negotiated. Faults will occur if the IP 400 settings do not correspond to those of the Ethernet switch.

  • Page 32: Configuration Of The Wan Interfaces

    Any ISDN or PPPoE router with PPP capability can serve as a PPP remote entity. Fig. 5 on page 28 illustrates accessing a remote IP network using an IP 400 as an ISDN router. Fig. 6 on page 29 illustrates accessing the Internet via a DSL con- nection.

  • Page 34: General Considerations On The Configuration Of The Ppp Connections

    One specific application of the ISDN WAN interface is to dial-in to the gateway for maintenance purposes. This enables remote maintenance of the gateway, without necessarily having access to the local IP network, as illustrated by Fig. 8 on page 30. IP access only to the gateway !

  • Page 36: Settings For Outgoing Isdn Ppp Dial-Up Connections

    Configuration of the IP routes You can add separate IP routes for each PPP interface using the Add IP route button. The routes are configured in the same way as those for the Ethernet inter- face (see section 4.1 “Configuration of the Ethernet interface” from page 24). All IP routes must be defined explicitly.

  • Page 38 If this field remains empty, all data calls will be accepted at the selected ISDN interfaces. In this case however, it is not possible to assign these calls to the various PPP interfaces. Such configurations should thus be avoided. • Check the Allow incoming calls box.

  • Page 39: Settings For Incoming And Outgoing Isdn Ppp Dial-Up Connections

    Expansion to Multilink You can accept a multilink connection via two bundled channels instead of a con- nection via a single B channel. • Check the Multilink box. • Leave the Dial remote number and Local subscriber number fields empty in the Numbers for 2nd Multilink channel area. Your gateway will accept calls for both channels on the same number, configured in the Sub- scriber number field.

  • Page 42: The Remote Maintenance Facility In The Standard Configuration

    4.2.7 The remote maintenance facility in the standard configuration In the standard configuration, the PPP ISDN interface is configured to dial-up up for remote maintenance. This allows the gateway to be configured remotely from any PC with an ISDN card and a PPP remote data transmission programme (e.g. Windows DUN).

  • Page 43: Allowing Dial-Up Access To The Entire Network

    This configuration means that by plugging in an ISDN BRI point-to-multipoint exchange connection (e.g. a BRI connection to the exchange or a BRI line from a PBX) to the PPP interface, the gateway can be configured from any PC with a PPP dial up application.

  • Page 44: The Enum Protocol

    4.2.9 The ENUM protocol ENUM stands for a protocol, which has to do with mapping so-called E.164 num- bers to Uniform Resource Identifiers (URI). It defines rules to uniquely map a tel- ephone number to a domain. This domain can then be used, for example, to iden- tify addresses for IP telephony.

  • Page 45: To Set Up The Enum Protocol On An Innovaphone Gateway

    To be able to use the ENUM protocol, 3 VoIP interfaces have to be set up. To transmit the ENUM calls via the innovaphone PBX, to receive incoming ENUM calls and to forward these incoming calls to the innovaphone PBX.

  • Page 49: Rerouting Outgoing Calls

    4.2.11 Rerouting outgoing calls Rerouting is supported. If the call to an ENUM interface should fail to be estab- lished, rerouting means looking for another, subsequent route and trying again. If rerouting is to work correctly, the Final map option must have been acti- vated for the three routes just set - international, national and local prefix.

  • Page 50: Configuration Of The Isdn Interfaces

    Configuration of the ISDN interfaces The IP 400 has two “virtual” interfaces, whose configuration is described in sec- tion 5.3 “Considerations on the configuration of the virtual interfaces” from page 66. The IP 400 has ISDN interfaces. To configure the ISDN interfaces you first need to decide about the following points: •...

    Volume adjustment In some cases, it is desirable to adjust the basic volume level of an interface. The volume of the ISDN interfaces can be set, in the configuration applet, under Con- fig > ISDN, tone and HTTP Interfaces > TEL or PRI under Interface con- figuration in the Volume field, in the range from -31 to +32.

    Single digit dialling on terminals on point-to-multipoint connec- tions Normally, single digit dialling (overlapped sending) is not used to call terminals (i.e. devices in TE mode) on point-to-multipoint connections. Under certain cir- cumstances however, it is possible for gateways to be connected to a PBX system in precisely this mode and then also support incoming single digit dialling (over- lapped receive).

  • Page 55: Usage At A Public Exchange Line (Dial-Up Or Permanent Connection)

    For incoming calls at the ISDN interface, this is usually only done in the direction of the calling party if the interface is in NT mode, not however if it is in TE mode. In a few cases though, in particular when linking up PBXs via tie lines, it can be useful to also generate these tones in TE mode.
  • Page 56 • Use as an IP router for operation on a permanent connection (IP 400 only). In this way, the gateway is connected to a remote PPP entity (at the ISP or in the company network) via a 64 kbit/s or 128 kbit/s permanent ISDN connec- tion.

    This type of connection only occurs in connection with BRI interfaces and is thus usually only relevant for the IP 400. In this case, the PBX is connected to the gateway in the same way as an exchange line, as described in section 5.2.1 “Usage at a public exchange line (dial-up or...

  • Page 63: Use On A Pbx Tie Line

    The limitations mentioned above generally do not apply, if the PBX provides a point-to-point connection on the subscriber line (this is often referred to as a “tie line”). Note however, that the gateway does not support any proprietary subscriber pro- tocols for operating telephones on PBXs.

  • Page 65: Looping The Gateway Into An Existing Public Exchange Line

    Per exchange line, this requires one ISDN interface to the public exchange (TE mode) and one to the PBX (NT mode) in the gateway. The IP 400 can also be looped into an exchange line, but in this mode not all of the four possible calls can actually be made in parallel, since the IP 400 has two NT interfaces (tel1 and tel2), but only has one TE interface (PPP).

  • Page 66: Dealing With The Various Isdn Address Types

    5.2.7 Dealing with the various ISDN address types Call numbers are always treated internally by the gateway as unknown type of number. In ISDN however, there are various types of call numbers (see Table 8) with the effect that call numbers are only ever interpreted in combination with their number types.

    VoIP end points These are devices that implement the end points of telephone calls. For example an IP telephone such as the innovaphone IP 200 or VoIP software such as innovaphone Softwarephone. Such end points are usually assigned to just a single user.
  • Page 72 Gatekeepers are optional however, since, optionally, end points and gateways can also communicate directly with one another. Your innovaphone gateway always includes a gatekeeper that you can use as desired. Gatekeepers and VoIP end points or VoIP gateways usually communicate via the so called RAS protocol.

  • Page 73: Understanding Your Gateway's Gatekeeper

    Fig. 19 on page 69 shows a scenario with an IP telephone, an ISDN gateway and a gatekeeper. The gatekeeper can be another innovaphone gateway or, alter- natively, it can be the gatekeeper incorporated in every innovaphone gateway. For a clearer understanding though, the gatekeeper and ISDN gateway are shown separately.
  • Page 74 keeper's device management. They submit their identity and their current IP address in the process. This step requires the RAS protocol and therefore doesn't apply when operating without the RAS protocol. • The IP telephone initiates a call (3.) and sets up a signalling connection to the gatekeeper.
  • Page 75 Many gatekeepers and also some VoIP devices do not support the Discovery procedure. In this case the gatekeeper's IP address has to be configured in the device to be registered. Likewise, multicasts of routers are not usually transmitted. That is why the IP address of the gatekeeper also has to be reg- istered if it is separated from the registering device by a router.

  • Page 76: Gatekeeper Discovery

    A number of VoIP devices do not support the RAS protocol. Such devices can nev- ertheless still be managed by being configured statically (hence with fixed IP addresses) in the gatekeeper. Steps 1 and 2 then no longer apply in the sequence in Fig.

    Static management of VoIP devices If you are using VoIP devices that don't support dynamic registration using the RAS protocol, they must be configured statically. As a consequence, the accessi- bility of the devices no longer has to be constantly checked, and it is not possible to use changeable IP addresses (i.e.

  • Page 93 Calls from different interfaces are often handled in the same way. In the scenario illustrated by Fig. 22 on page 87 it may, for example, be desired to allow calls from both TEL1 and TEL2. That is why a number of interfaces can be specified as permitted sources for a route.
  • Page 94 Fig. 25 Routes with call number replacement After all, it is occasionally necessary to define routes that depend on the calling number. To do this, so called CGPN Maps are attached to the Maps, very much in the same way as the Maps that are attached to the routes. This not only allows the calling numbers to be modified in order, for example, to suppress the exten- sion for outgoing calls, but also the entire Map to be made dependent on the call- ing number.
