General information

The actual interoperability tests were executed by inexio, not by the Swyx TAP.

Important: The profile for SIP provider inexio is available from SwyxWare2015R40.2 on.


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).
During creation of the SIP trunk group, profile 'inexio KGaA C5 on-net v2'' must be selected.

  • FAX transmission

Inexio does not support T.38 for FAX transmission, but transparently passes the appropriate data between the two parties. To ensure that FAX transmission is also working with parties which do not support T.38, it is necessary to deselect T.38 as support dodec in the codec settings of the trunk properties.
