18.2 Creation of an ENUM Trunk Group
We recommend creating an ENUM trunk group before creating an ENUM trunk.
General parameters such as permissions, location and routings are specified in this group. When creating a trunk, you then simply assign the trunk group to the trunk. As a member of the group, the trunk is thus given the corresponding parameters.
How to create an ENUM trunk group
1 Open the SwyxWare Administration and choose the SwyxServer.
2 In the left side of the SwyxWare Administration window, click with the right mouse button on "Trunk Groups" and select the entry "Add Trunk Group…" in the context menu.
The "Add Trunk Group…" wizard will appear.
3 Click on "Next>".
4 Name and description of the trunk group:
Enter the name of the trunk group, and a description.
Click on "Next>".
5 Type of trunk group:
Enter the type of trunk group here, in this case "ENUM".
Only the "ENUM" option appears for selection in the "Profile" field.
Click on "Next>".
6 ENUM settings:
To allow incoming calls from the Internet to SIP-URIs to be received via this trunk, enter the dedicated realm here, which must be mapped to the SIP-URIs 'dialed' from outside, e. g., ‘company.com'.
DTMF method:
This mode defines a method based on user keyboard entries (DTMF signalize).
You can choose from a variety of options:
None. DTMF signalization is deactivated
RFC2833_Event: RFC2833_Event: DTMF signalization, based on the event mechanism described in RFC2833, will be used.
Info Method DTMF Relay DTMF signalling as recommended by Cisco (applicationtype DtmfRelay) will be used
Click on "Next>".
7 Settings for the STUN server
If you wish to use STUN, you can use the free STUN server "stunserver.org" with port "3478".
Click on "Next>".
8 Definition of routing:
Specify for which calls this Trunk Group should be used. When entering call numbers or URIs you can use placeholders (*), e.g. "+*" for all external numbers or "*" for all internal numbers. Multiple numbers/URIs are separated by a semicolon. You have several different options:
for all external calls
only for external calls to the following destination number or SIP-URI
for all external calls and all unassigned internal numbers
For the following internal numbers
Create no routing records for the moment
Click on "Next>".
9 Call Permission
Specify the Calling Rights profile for the Trunk Group. This Calling Rights profile applies to the incoming calls over this Trunk Group.
Click on "Next >".
10 Location profile:
Define the location. This profile also includes the definition of e.g. country code and public line access.
Click on "Next>".
11 Click "Finish".
The new ENUM trunk group is created, and is available for further configuration.
