Information und configuration hints for SIP provider RoutIT (Netherlands).


General information

RoutIT 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.

RoutIT is operating with a number of different servers. Therefore it is not possible to preconfigure the Proxy Server in the "SIP" tab of the Trunkgroup properties. In this field, please enter the IP address or server name that RoutIT has named you. RoutIT will usually send you information about the registration domain, too. These information must be entered into the field "Realm" in the "SIP" tab of the Trunkgroup properties.


In certain situations, it may occur that RoutIT will play announcements and will simultanously perform a codec change to G.722. This codec change is not supported by SwyxWare, therefore these announcements cannot be played to the user. To prevent this situation, you have to exclude G.722 in the Codecs/Channel tab of the Trunk Properties dialog.

For T38 negotiation, it is necessary to set the option "Remove T.38 from initial negotiation (SIP INVITE)" in the Codecs/Channel tab of the Trunk Properties dialog

In certain situations, it may occur that RoutIT changes some characteristica of the RTP stream. With a SwyxWare2011R2, this may lead to a oneway voicechannel if internal encryption is active. When running a SwyxWare2011R2, internal encryption must be deactivated in the Encryption tab of the SwyxServer properties.

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 SwyxWare2013 R4 on, the provider profile for RoutIT is already available in the list of provider profiles and the CustomProviderProfiles.config is no longer necessary.
