VoIP gateway IP400 version 5.01
In the next step we will configure an interface for incoming calls, if this hasn't
already been done. The interface must permit the acceptance of calls from any IP
address, without previous registration:
• In the configuration applet, select the path
Config > VoIP Interfaces
> GWn
, where n corresponds to the VoIP interface to be configured, e. g.
GW3
.
• In the area
VoIP Interface name and general config
in the field
Description
enter a brief description, e. g.
World
.
• In the
Mode
area, enter the correct mode
Gateway (w.o. registration)
.
• In the area
Remote gateway address
in the field
IP address
, enter the IP
address
0.0.0.0
.
With the entries
Gateway (w.o. registration)
and IP-Adresse
0.0.0.0
incom-
ing calls from persons unknown will be accepted. See also section 6.3 “Static man-
agement of VoIP devices” from page 84.
With that, the configuration of the interface for incoming calls is finished.
To establish a call via an ENUM enquiry, at least one route must lead to the newly
created ENUM interface. For information on the routes, see section 7.1 “General
considerations on the configuration of call routing” from page 87. To create a
route in the ENUM interface, proceed as follows:
• In the configuration applet, choose the path
Config > Routing table
.
• Click on the
Add route
button to add a further entry to the routing table.
Note the order of the routes here. The new route is always inserted after the
current entry.
• In the
Description
enter a name for the route, e. g.
to ENUM
.
• Select the entry underneath the new route
to ENUM
(the one with the “
->
”).
• Tick the checkboxes of the gateways and ISDN-interfaces in the
Enable
calls from interfaces
area to validate them as sources for this route. You
will only be offered the interfaces, which have been configured. In our pre-
vious example, that was
GW2
.
• From the
Default call destination
list, select the destination to which the
calls are to be connected - i.e. the new ENUM interface. In our previous
example, that was
GW1
.
Now, the route to the ENUM interface has been created. As ENUM requests have
to be transmitted with complete E.164 numbers, it is necessary to prepare the
number to be dialled accordingly, to be able to create the corresponding ENUM
domain.
