General
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.
Platforms
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.
SwyxON
The MK-VoiceConnect trunk of MK-Netzdienste is not released for central connection in the data center.
Configuration
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.
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.

IMPORTANT 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. |

Restrictions:
MK-Netzdienste supports T.38 codec transparency. The T.38 negotiation therefore takes place between sender and receiver. If the remote station does not support T.38, or T.38 is not permitted for network transitions to other providers, the FAX transmission takes place with G.711.
