Trunks and Trunk Groups
Trunks and trunk groups as connections from a SwyxWare installation to the outside world
We distinguish between various trunk types:
ISDN Trunk (SwyxGate lines)
SIP Trunk
SIP trunks enable the use of VoIP services that are provided by carriers or service providers. The service provider provides you with a phone number or a number range. Alternatively the SwyxWare users can be assigned SIP addresses (SIP-URIs, e.g. "tom.jones@swyx.com") by the provider, which can be used as an "email address for a telephone". By this means, SwyxWare users can globally reach other SIP-URIs, and be reached themselves. If this service provider also offers gateway services, it will also be possible to reach any phone in the public telephone network via an SIP trunk and the underlying gateway of the provider.
For more information on how to set up an SIP trunk, please see
Chapter SIP Links.
SIP Gateway Trunk
SIP gateway trunks are used for activating gateways which are themselves reached by SwyxServer via an SIP connection. Thus e.g. SwyxConnect is addressed within SwyxWare as a SIP gateway trunk. This allows e.g. telephones in small branch offices to be operated with a local gateway in each case and with a local direct connection to the PSTN. In this way, sophisticated requirements of a company network can also be met when there are numerous small sites (e.g. many shops in a chain of stores).
Only gateways for which profiles are included in the delivery are supported at present.
ENUM Trunk
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.
SwyxLink Trunk (Server-server coupling)
It is also possible to use the Collaboration, Video and Instant Messaging features across different servers via the SwyxLink trunk.
