Once you have created a SIP gateway trunk group, you can proceed to create individual trunks to this SIP gateway.
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 SIP registration:
Enter the parameters the SIP gateway needs to log onto SwyxServer via this trunk.
SIP User ID:
The user ID is combined with the realm to create the SIP address (URI).
SIP Authentication method:
Indicate whether or not the gateway needs to authenticate itself.
SIP user name and password:
The user name and password are required for authentication.
This logon data must be entered in the same format as when was configured.
7 Numbers:
Please enter the Public Numbers to be routed by this Trunk..
To map several individual numbers or number ranges, enter only one number or one range here, and add the others subsequently in the trunk properties (
The "Numbers" Tab).
8 Codecs:
With the help of the Codec you select how the voice is compressed for transmission. The following options are available:
Specify which Codecs should be permitted for this trunk.
Voice, low bandwidth (G.729)
High compression. A voice connection requires approximately 24 kbits/s.
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 64 kbits/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 20 kbits/s.
9 Number of channels:
Enter how many calls may be routed via this trunk at the same time.
The maximum number of channels available is determined by the codec used and the bandwidth of the connection between the headquarters and branch office.
10 Computer name:
Apply the default computer name.
11 Click "Finish".
The new Trunk is created, and is available for further configuration.
