8.1 Create trunk groups
A trunk must be assigned to a trunk group. Create a trunk group of the required type (SIP, SIP gateway, etc.) to be able to subsequently create trunks of the corresponding type.
To create a trunk group
1 In the menu, select Connections | Trunks.
2 Select Trunk groups.
3 A list appears with all Trunk Groups.
4 Click on Create Trunk Group .resp Create SwyxLink group .
*The configuration wizard appears Create trunk group.
5 Set general settings for the trunk group.

Explanation
Name
Enter a name for the trunk group.
The name must be unambiguous within SwyxWare.
Description
Enter a description, if applicable.
Trunk group type
Choose a trunk type:
The trunks subsequently created in this trunk group will have the property of the selected type.
 
SIP Trunk
SIP trunks enable the use of VoIP services. The service provider usually assigns a number range or SIP URIs. If the service provider in question also offers gateway services, numbers in the public telephone network can also be reached via a SIP trunk and the provider's gateway behind it.
 
SIP Gateway Trunk
SIP gateway trunks are used for activating gateways which are themselves reached by SwyxServer via an SIP connection. This makes it possible, for example, to operate telephones in small branches and branch offices, each with a local gateway and with a local direct connection to the public telephone network.
Only gateways for which profiles are included in the delivery are supported at present.
 
ENUM Trunk
An ENUM link enables you to make SIP calls with ENUM number resolution via the Internet.
A user of a SIP phone is thus able to investigate the SIP address automatically using only the telephone number of the called party, and to convert the number into the SIP address. The called party can then be reached over the IP network in spite of using a 'normal' phone number. This postulate that the called party is registered at ENUM.
 
Trunk (Server-server coupling)
SwyxServer at different locations are connected to each other via a SwyxLink trunk over an IP route. The SwyxLinkManager takes over the control of the connection. Within the configuration of a SwyxLink trunk, the connection to other sites can be SwyxWare Sites can be defined so that status information (logged off, available, currently speaking) can also be exchanged between users who are logged on to different servers. See also 4.14 Intersite connections
Location
Select one of the locations, see Creating and editing Locations.
The location defines prefixes and time zone for the trunk group
Provider profile
(not for SwyxLink group)
Select a profile.
A trunk group profile specifies how the trunk interprets and handles the call numbers. Depending on the Trunk type, a number of predefined profiles are available. The phone number format is defined for each of these profiles. For SIP Trunks in particular, the profile specifies the provider and the necessary SIP parameters.

Currently, only one profile exists for each of the SwyxLink and ENUM trunk types.
Record all Trunk Calls
If you activate the checkbox "Enable Trunk recording", all calls that are made via this trunk group will be permanently recorded, provided this is activated in the SwyxServer settings, see 14.2 Trunk Recording
6 Click on Next.
7 If necessary, set the SIP registration for the trunk group (SIP type only).
* 
The registrar port must match the selected transport protocol. Leave the filed empty if you did not receive information on the port by your Service provider. The port is determined via DNS query.

Explanation
SIP Registration
Check the box if SIP registration is to be used.
Registrar
Enter the server address of the registrar.
REGISTER messages are sent to this address.
Registrar Port
Set the port on which the configured registrar will accept the registration request.
Re-registration interval (seconds)
Set the frequency of re-registration.
e.g. 120 (seconds)
A small value will allow you to quickly recognize the loss of the SIP connection to the provider. A high value results in lower network burden in standby.
