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.

The configuration wizard appears Create trunk group.

5 Set general settings for the trunk group.

Label	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 to control gateways that are themselves reached by SwyxServer via a SIP connection. This allows, for example, telephones in small branch offices and subsidiaries to be operated with a local gateway in each case 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. This means, for example, that the user of a SIP telephone can automatically determine the SIP address of the desired call partner simply by entering the telephone number and have the telephone number converted to the SIP address. The called party can then be reached over the IP network in spite of using a 'normal' phone number. This requires that the desired call partner is registered with ENUM.
Location	Select one of the locations, see Creating and editing Locations. The location defines area codes and time zone for the trunk group
Provider profile	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. See also https://help.swyx.com/cpe/13.00/Administration/Swyx/en-US/index.html#context/help/sip_trunkgroup_$ Currently, only one profile exists for the trunk types ENUM.

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. If you have not received any information about the port from the service provider, leave the input field empty. The port is determined via DNS query.

Label	Explanation
SIP registration	Select the check 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.

8 Click on Next.

9 Set the forwarding.

Label	Explanation
Use trunks of this trunk group...	Specify for which calls this Trunk Group should be used. You can use wildcards (*) when entering phone numbers or URIs, see Placeholder 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
