17.3 Creating a SwyxLink Trunk
In order to make an additional SwyxServer available within SwyxWare, you can configure a SwyxLink trunk in the SwyxWare Administration. Each SwyxLink trunk represents a connection to a SwyxServer with the parameters configured for this purpose.
The SwyxLinkManager service, which is responsible for linking SwyxLink lines, is automatically installed with the standard version of the SwyxServer software.
How to configure a new SwyxLink trunk
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 SwyxLink trunk:
Each inter-location connection is managed by exactly one SwyxLinkManager. If you would like to manage the SwyxLink on this side of the connection, select "Locally managed SwyxLink trunk". This SwyxLink must then be configured on the other side as "Remotely managed".
Click on "Next >".
7 Select remote SwyxServer (when locally managed only):
Enter the name of the SwyxServer for which this SwyxLink trunk is to be configured here.
With "Check server...", SwyxServer establishes a test connection to the remote SwyxServer.
Make sure that there is a transparent TCP/IP connection between the server on which the LinkManager service (local SwyxLink) is running, and all clients on the remote side and the SwyxServer.
Click on "Next >".
SwyxServer attempts to contact the remote server entered. If this attempt fails, you will receive a message. You can ignore the error message at this point and proceed with the creation of the trunk.
Click on "Next>".
8 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).
Click on "Next >".
9 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. A voice connection requires approximately 64kbits/s.
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
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>".
10 Voice channels:
Enter how many calls may be routed via this trunk at the same time.
Using a SIP trunk, the provider will define how many connections at the same time will be possible. The maximum number of channels will be defined by the bandwidth to the provider and the Codec settings (i. e. the bandwidth per call).
Click on "Next>".
11 Intersite Settings:
You configure a connection to one or more further SwyxServers here. This configuration means that status information ("Logged off", "Away", "Do Not Disturb", "Speaking" etc.) can now be exchanged between users of different SwyxServers. As of version 2011 R2, the collaboration, video and instant messaging feature (only SwyxIt! Messenger, not Swyx Messenger) can be enabled for employees. Furthermore, users are shown in the Global Phonebook of the connected servers.
Various connection types are differentiated in the Intersite settings:
Without any presence interaction:
Click on "Next>" and proceed with step
(14).
The remote SwyxServer is in the same organization:
Choose this option if the remote SwyxServer is in the same organization as the SwyxServer you are presently administering. See
l In the same organization.
Click on "Next" and proceed with step
(12).
The remote SwyxServer is in another organization:
Choose this option if the remote SwyxServer is in another organization than the SwyxServer you are presently administering. See also
l From another organization.
Click on "Next" and proceed with step
(12).
12 Settings for cross-server status signaling/ communication:
Specify which numbers should be synchronized over this trunk, and what information should be transmitted.
Number synchronization
Internal numbers
If you activate this option, only the users' internal numbers will be shown in the Global Phonebook on all sites.
| An absolute prerequisite for the synchronization of internal numbers is a valid and unique number plan, as otherwise, in the event of duplicates, individual numbers may be discarded. See also 10 Numbers and Number Mappings. |
Public numbers
If you activate this option, only the users' public numbers will be shown in the Global Phonebook on all SwyxServer sites.
Internal and public call numbers
When this option is selected, both the internal and the public call numbers of users will be shown in the Global Phonebook on all sites.
Data synchronization:
User Pictures
Say here whether the user pictures stored by the user should likewise be synchronized between the different servers. To save bandwidth, you can deactivate this option.
The trunk should be used for the transmission of:
Calls.
Video
Collaboration
SwyxIt! ClassicMeeting
Status information or
Instant Messaging
If you deactivate calls, the video, collaboration and SwyxIt! Classic meeting features are deactivated automatically. If you deactivate the status information button, you are not able to choose Instant Messaging See also
Use of the trunk.
Click on "Next >".
13 If you have selected the Intersite connection "From another organization", then you select here the groups that should be visible on the remote SwyxServer.
Otherwise, proceed with step
(14).
Click on "Next>".
| When the Intersite connections are configured within the SwyxLink, status signaling between the different SwyxWare sites is not automatically activated. You then have to configure the relationship of the users/groups, to specify precisely who should be signaled about the status of another user or group. For how to configure the relationships between users and groups, see 11.2.8 The "Properties…" Dialog: The "Relationships" Tab |
14 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.
15 Click "Finish".
The new Trunk is created, and is available for further configuration.
