Information und configuration hints for SIP provider M-net (Germany).


General information

This article refers to a SIP Trunk of the domain

M-net is offering a SIP trunk with user authentication. You have received information about UserID, UserName and UserPassword, whereas the naming may differ, or you might have only received UserName and -password. In this case, UserID and UserName are identical. 

The actual interoperability tests were executed by M-net itself, not by the Swyx Technology Alliance Program.


During creation of the SIP trunk group, profile 'M-net (DE)' must be selected.


In order to assign incoming calls to the correct trunk, it is necessary to configure a SIP URI for the trunk. The assigned number block and the numberformat must be considered.
Numberblock: +49 89 1234560 ... +49 89 1234569
In this case, the SIP URI must be entered in the format +4989123456*@*.
For your convenience the generated CustomProviderProfiles.config is available for download at the end of this article. Extended information about how to use this file can be found at Configuration and Adaptation of SIP Providers via Provider Profiles (kb3436).
Important: From SwyxWare v11.00.0.0 on, the new provider profile for M-net (DE) is available in the list of provider profiles and the CustomProviderProfiles.config is no longer necessary.
