Information und configuration hints for SIP provider OpenIP (France).


General information

The following information are valid for a SwyxWare 11 or later and cannot necessarily applied to earlier versions.
OpenIP  is offering a SIP trunk with user authentication. Along with the assigned number range and server information, you also need UserID, UserName and UserPassword. Please be aware that the naming may differ, or you might have only received UserName and -password. In this case, UserID and UserName are identical.

There is a dedicated SwyxWare profile for the OpenIP SIP trunks available. OpenIP therefore must be informed if a SwyxWare is connected to their SIP trunk. Otherwise there is a risk of problems in the SIP communication and number format.


SwyxWare: The SIP Trunk from OpenIP can be used from SwyxWare on. When using an earlier version of SwyxWare incompatibilities cannot be excluded and use is at your own risk.

SwyxON: The SIP Trunk from OpenIP is suitable for central connection in the data center.


When creating the SIP trunk group, select the profile 'OpenIP (FR)'. If the profile is not included in the corresponding list, you can download the required CustomProviderProfiles.config for SwyxWare at the end of this article. For more information about using this file, see Configuration and Adaptation of SIP Providers via Provider Profiles (kb3436).

After creating the trunk group, in the property settings of the trunk group, on tab 'Profile', it is necessary to to add special number replacement rules. The following rules need to be added for inbound, calling party:
+*  -> +*
*   -> +[cc]*


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: +33 970 112230 ... +33 970112239
In this case the SIP URI must be entered in the format +3397011223*@* .

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 on, the provider profile for OpenIP is already available in the list of provider profiles and the CustomProviderProfiles.config is no longer necessary.

FAX transmission

OpenIP does not support the T.38 protocol, which is strongly recommended for FAX transmission in an IP environment. The alternative method for FAX transmission via G.711 is supported from SwyxWare2015R3 on. In oder to prevent the intended T.38 stream switch, it is necessary to remove the T.38 codec from the list of supported codecs.
Note: Quality and reliability of a FAX transmission via G.711 strongly depends on the end-to-end network connection. Since the control and redundancy information from the T.38 protocol are missing, especially the transmission of larger documents may fail.
