You can now create ENUM trunks.
The service SwyxLinkManager, which is responsible for linking ISDN lines, is automatically installed with the standard version of the SwyxServer software.
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 "Trunks" and select the entry "Add Trunk…" in the context menu.
3 An "Add new Trunk Wizard" opens up.
Click on "Next>".
4 Trunk name:
Enter a name and a short description for the new trunk here.
Click on "Next>".
5 Selection of a trunk group:
Select the trunk group here to which this trunk should be assigned.
General settings such as routings, rights and location-specific parameters are specified in the trunk group. You can use "New Trunk Group..." to create a new trunk group, and then continue with the creation of a trunk.
Click on "Next>".
6 Numbers:
Please enter the Public Numbers to be routed by this Trunk..
In respect of the generation of SIP-URIs, numbers configured here are also converted into the following format:
sip:<number>@<realm>
The realm is the same one defined in the trunk group.
To map several individual numbers or number ranges to this trunk, enter only one number or one range here, and add the others subsequently in the trunk properties (
The "Numbers" Tab).
7 SIP-URI
Enter the SIP addresses (URIs) to be managed by this trunk here. A SIP has the following format:
SIP:<Name 1>@<Name 2>
where <Name 1> represents the user name and <Name 2> the realm. Although the realm is set by default when the trunk group is selected, it can be overwritten individually here.
To make things easier, you can use '*' as a placeholder, e.g., enter '*@company.com' for all users with the realm 'company.com'.
8 Codecs:
With the help of the Codec you select how the voice is compressed for transmission. The following options are available:
If the Codec priority "Prefer Quality" is selected, the Codecs are provided in the sequence G.722, G.711a, G.711µ, G.729 or Fax over IP. Specify the filter(s) you want:
Voice, highest bandwidth (G.722)
HD quality
Voice, high bandwidth (G.711a, G.711µ)
The voice data is slightly compressed. This keeps the packet delay time in the LAN (Local Area Network) to a minimum. A voice connection requires approximately 64kbits/s.
Voice, low bandwidth (G.729)
High compression. A voice connection requires
approximately 24kbits/s.
Fax over IP
In this case, the special fax protocol T.38 is used, which takes the set-up of the IP network into consideration. A fax connection using T.38 requires approximately 20kbits/s.
If the Codec priority "Prefer low bandwidth" is selected, the Codecs sequence changes to G.729, G.722, G.711a, G.711µ, Fax over IP. The aim here is to use as little bandwidth as possible. Here too, specify the filter(s).
Click on "Next>".
If there are several voice codecs selected, SwyxServer will filter voice data according to the current settings. The communicating sides will have to decide which voice codec to use.
It won't be written in the change log, if a Codec was activated or deactivated. See also
Change log.
9 Voice channels:
Enter how many calls may be routed via this trunk at the same time.
The maximum number of voice channels is calculated on the basis of the bandwidth of the IP connection and terminal used.
10 Computer name:
Enter the name of the computer on which the SwyxLinkManager is managed. Use the name of the computer as it appears in the computer properties.
11 Click "Finish".
The new Trunk is created, and is available for further configuration.
Please note that when using a NAT router, port forwarding must be configured so that the SIP messages, which are received on the public IP address of the NAT router on port 5060 are also forwarded to the SwyxLinkManager on port 65002 in the internal network.
