The MK-VoiceConnect SIP trunk of MK-Netzdienste was first tested and released with a SwyxWare 11.
The MK-VoiceConnect trunk of MK-Netzdienste is a SIP trunk with user authentication, i.e. you get information about user ID, user name and password from MK-Netzdienste. The names may differ, or you will only receive a name or ID with password. In this case the user ID is identical to the user name when configuring the SIP trunk in SwyxWare.
The MK-VoiceConnect trunk of MK-Netzdienste can be used without restrictions from SwyxWare 11. When using an earlier version of SwyxWare incompatibilities cannot be excluded and use is at your own risk.
The MK-VoiceConnect trunk of MK-Netzdienste is released for central connection in the data center.
During creation of the SIP Trunkgroup, profile 'MK Netzdienste (DE)' must be selected. In the configuration dialogs of the SIP trunk group and the actual SIP trunk, the default settings can be accepted.
22.04.2021: To connect the SIP Trunk of MK-Netzdienste a STUN server is required. From SwyxWare 12.30 on this is already configured in the provider profile. For older SwyxWare versions the STUN server has to be added manually via the properties of the SIP trunk group in the tab "SIP". In the field STUN the STUN server of MK-Netzdienste has to be entered: stun.mk.de.
In the codec dialog for FAX transmission via T.38 the two options "Remove T.38 codec from initial invite" and "Prohibit T.38 reinvite by sender" must be activated.
- Incoming/outgoing national calls
- Incoming/outgoing international calls
- Correct Calling Line Identificaion (CLI) on national and international calls

Verifying interoperability between different SIP providers and the Swyx solution is part of the Enreach Technology Alliance Programme (TAP) tasks. Due to different implementations of the SIP RFCs, it is necessary to determine and provide an individual configuration for each SIP provider.
Within the TAP, Enreach tests a large number of national and international SIP providers in order to make statements about the interoperability with the Swyx solution and the functional scope of the respective SIP trunk. These results and, if needed, configuration advice are published in Help Center articles.
Enreach is in close contact with selected SIP providers to ensure a quick troubleshooting in case of incompatibilities. In addition, tests are repeated at regular intervals to ensure consistent quality.
Despite regular retests it cannot be excluded that incompatibilities with the Swyx solution may occur due to changes in the SIP connection on the provider side or that the provided profile is no longer valid. After creating the trunk group or SIP trunk, the profile settings should be compared with the provider's information and adjusted accordingly in case of deviations.
However, should incompatibilities or problems occur with a tested SIP trunk, no claims for recourse against Enreach GmbH can be derived from this. In such cases, you can contact Enreach Support via your specialist dealer.
