SIP Provider UPC Business (AT)

UPC Business 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. Besides, you need an IP address which was assigned by UPC and which gets connected to the SIP trunk.

Configuration

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.

Example:
Numberblock: +43 662 1234560 ... +43 662 1234569
In this case, the SIP URI must be entered in the format 0662123456*@*.

On outgoing calls UPC changes some characteristica of the RTP stream call setup and call answering. This may lead to a oneway voicechannel if internal encryption is active. Therefore, in the tab "Encryption" of the SwyxServer properties, you have to deactivate internal encryption.

Exclude G.722 in the Codecs/Channel tab of the Trunk Properties dialog.

Support for feature CLIP No SCreening must explicitely be requested from UPC.

Support for T.38 and FAX transmission must explicitely be requested from UPC.

There is a dedicated Swyx profile for the Transcoding Gateway from UPC in order to transmit T.38 and DTMF. This must be activated on the UPC side when configuring the trunk.

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 How To: Configuration and Adaptation of SIP Providers via Provider Profiles.
